Yingshan, Sichuan: draw ecological pictures together to protect the clear water and blue sky

On the vast land of Northeast Sichuan, Yingshan County, Nanchong City, Sichuan Province, is like a bright pearl inlaid between mountains and rivers. Once, the rapid advancement of industrialization and urbanization brought challenges to the environmental governance of this land. In recent years, Yingshan County, with the determination of breaking the boat, has continued to make up for weaknesses and strengthen the foundation, overcome difficulties, implemented the combination of pollution control and ecological restoration, insisted on paying equal attention to environmental protection education and environmental treatment, and blazed a green development path; A "community of life" of mountains, rivers, forests, fields, lakes, grasses and sands has been built in all directions, regions and processes.

Building a three-dimensional clean water ecology with the original "source" of clean water

In the evening, the author walked along the Beimen River (urban section of Yingshan River) in Yingshan County, and saw that the fish were flying at the bottom, the water was clear and the bank was green, and the breeze was blowing, which made people relaxed and happy.

Uncle Zhang, the witness of the change of Beimen River, told the author that he lived along the Beimen River since he was a child. Many years ago, most of people's production and domestic water came from this river. The river has nurtured generations of mountain campers. It is the "Mother River" in the hearts of mountain campers. However, the pace of urban development and water ecological protection is inconsistent. The friendly face of the "Mother River" is gradually blurred in the hearts of the older generation of mountain campers.

"In recent years, the county Party committee and the county government have carried out ecological restoration of Beimen River, and the river has recovered its former style." Uncle Zhang's words awakened everyone's dusty memory and reflected the remarkable results of water ecological environment treatment in recent years.

According to chenmeng, a staff member of Yingshan Ecological Environment Bureau, in recent years, on the basis of intercepting pollutants and controlling sources along the Beimen River, the water ecological environment protection project of Yingshan River Basin has been implemented, with an investment of more than 20million yuan, and a vigorous battle for river governance has been started: the ecological restoration project has been implemented for the Beimen river passing through the city, ecological slope protection, artificial wetlands, plant isolation zones, etc. have been built along the line, and in-situ microbial remediation has been used to decompose and mineralize the pollutants in the river sediment, so as to achieve the purpose of water quality improvement.

"The construction of ecological floating islands, the planting of hydrophilic and emergent plants, and the creation of ecological landscapes have improved the ecological environment on both sides of the river, promoted the restoration of the ecological function of the river, and improved the quality of the living environment. The Beimen river has regained its former vitality, effectively improving the happiness and satisfaction of the people," said Chen Meng.

Wangyiwei, a staff member of Yingshan Ecological Environment Bureau, introduced that recently, the ecological restoration project of the upper reaches of Yingshan River in Yingshan County has been started. It will harness more than 10 kilometers of river from Qingshui township to Langchi street, mainly to solve the problems of agriculture, non-point source pollution in towns and cities, solve water and soil loss, improve the self purification capacity of the ecological environment and the healthy level of the ecosystem, and achieve the goal of "there are rivers, fish, grass, and harmony between people and water".

The governance of Yingshan river is only a microcosm of the governance of water ecological environment in Yingshan County. It is understood that in recent years, Yingshan has carried out channel desilting, riverbed widening, embankment and slope protection for 37.81 km of rivers in the county, built 60000 square meters of artificial wetlands, and planted 16000 square meters of emergent and submerged plants, effectively reducing the internal pollution of rivers.

On June 21, the author walked into the Chengdong sewage treatment plant of Yingshan County, and saw that various mechanical equipment operated normally, and the treated sewage was rippling in the secondary sedimentation tank. According to staff member xuyongou, after the sewage transported from the county town through the pipe network enters the treatment plant, after the processes of removing impurities, separating mud and water, removing phosphorus and nitrogen, the sewage becomes clear water, which can be directly used for ecological water replenishment.

"The factory can process 50000 tons of sewage every day. Some of the treated water is discharged into Yingshan River, and some is transported to the reclaimed water hub of Yingshan County urban reclaimed water reuse project." Xu Yongou said that some of the water treated by the reclaimed water hub is pumped to the county people's Hospital for cooling medical equipment, and the other part is pumped to Zoumaling River to realize the ecological water replenishment of Nanmen river.

It is understood that the second sewage treatment plant in Yingshan economic and Technological Development Zone has been put into trial operation. A total of 87 urban and rural sewage treatment plants (stations) have been built in the county, realizing full coverage of urban and rural sewage treatment. The daily treatment capacity of urban and rural sewage exceeds 100000 tons, and the urban sewage treatment rate has been increased to 99%.

"Water control is the first step in Yingshan's ecological development." according to rangaoliang, director of Yingshan Ecological Environment Bureau, Yingshan has implemented four major measures, namely, sewage interception and source control, endogenous treatment, ecological restoration and living water quality improvement, which have effectively improved the county's water ecological environment and promoted the recycling and comprehensive utilization of water resources. The water quality of river sections assessed by four countries and cities has reached class III water quality, and the water quality of centralized drinking water sources in the county has reached 100%.

Turning waste into treasure and exploring the new path of "waste free city" construction

When the first ray of sunshine fell on Yingshan County, food waste collection and transportation vehicles shuttled through the streets of Yingshan County. The staff skillfully poured the food waste stored in professional garbage cans into the collection and transportation vehicles, and then transported it back to the food waste disposal center of Yingshan County for centralized treatment.

"We have 8 food waste collection and transportation vehicles, which are divided into 8 different lines to collect and transfer food waste regularly." huangzhiquan, a staff member of the county food waste disposal center, said that about 45 tons of food waste are collected and transported from the county every day. After solid-liquid separation, sorting and crushing, pressing and drying and other processes, the food waste has realized a "gorgeous transformation".

"The extracted oil becomes the raw material of industrial oil; the treated tail water is discharged to the county Chengdong sewage treatment plant through pipelines for further treatment; part of the residue after harmless treatment is used as the raw material for making organic fertilizer, and part is transported to the waste treatment plant for incineration and power generation." huangzhiquan said that the establishment of a food waste disposal center has reduced environmental pollution at the source and created economic benefits.

"More than 600 tons of domestic waste are transported from Yingshan, Pengan and Yilong every day. After 5 to 7 days of retting and fermentation in the waste storage pit, it can be used for incineration and power generation after dehydration. The daily power generation is about 300000 kwh, providing green power for the development of the city." the staff of Yingshan Sanfeng environmental protection energy Co., Ltd. introduced.

The staff also introduced that the leachate produced in the retting and fermentation process of the domestic waste heap, after treatment, becomes clear water, which is not only used for the circulating cooling system of the plant, but also used for watering flowers and plants and maintaining roads; The burned slag is the raw material for making floor tiles.

According to Wang Jin, director of Yingshan environmental sanitation Institute, Yingshan has built and improved a scientific and efficient garbage collection, storage and transportation system: more than 1000 first-class garbage collection and transportation points and more than 50 second-class garbage collection and transportation points have been set up in residential areas, courtyards, enterprises and institutions in the county. The first-class collection and transportation point shall carry out three times of cleaning and transportation in the morning, in the middle and in the evening every day to ensure the daily cleaning of garbage; When the amount of garbage in the transfer box at the secondary collection and transportation point reaches 80%, the automatic alarm system will send the signal back to the data center of Yingshan banglan environmental protection Co., Ltd., and the staff will quickly replace the full transfer box with the empty transfer box, and then transfer it to the three waste transfer stations in the county for compression treatment.

"Now, there are more than 200 garbage trucks running in urban and rural areas in the county, and 13 garbage transfer stations have been set up, realizing the full coverage of urban and rural solid waste collection and treatment." Wang Jin said.

"Yingshan has built a solid waste industrial park in Tuanshan village, Huilong Town, including waste incineration and power generation, medical waste disposal, classified waste disposal, construction waste disposal, slag disposal and other projects, realizing the resourceful disposal and utilization of the county's domestic waste and medical waste; at the same time, the Chengdu Kelong harmless treatment and Transfer Center for dead livestock and poultry in the industrial park is about to be completed and put into operation; the renewable resources recovery and utilization Industrial Park in Yingshan economic development zone is under intensive construction." according to relevant personnel of Yingshan County Government.

Publicizing the "five advances" and cultivating the new trend of the people's awareness of environmental protection

"We should save water and protect water resources; garbage should be put into different categories to prevent harmful garbage from polluting the environment..." recently, in front of the teaching building of Hongguang primary school in Yingshan County, a unique hand copied display of environmental protection knowledge attracted the students to stop and watch. The teachers spoke carefully and the students listened carefully.

According to Wang Dong, the principal of the school, the flag raising ceremony of the school should be interspersed with activities such as environmental protection knowledge recitation and resource conservation explanation, so as to promote environmental protection knowledge to children and let environmental protection ideas sprout in the hearts of young children.

"Not only that, all classes also use class meetings and morning meetings to carry out Q & A on environmental protection theme knowledge and integrate environmental protection concepts into daily teaching; special education activities are carried out in combination with special periods such as' China Water Week 'and' World Environment Day '. Environmental protection education has been integrated into all aspects of daily teaching," Wang said.

Yingshan Hongguang primary school has paid close attention to environmental protection education, which has attracted the attention of West China Normal University. Not long ago, West China Normal University signed the agreement on co construction of environmental education base with the University, and awarded the University as the "environmental education base" of West China Normal University. According to the agreement, West China Normal University will develop environmental education and environmental science popularization materials every year, arrange experts to carry out environmental education and science popularization activities in Hongguang primary school, and receive teachers and students from the school to carry out visit, study and practice activities. This cooperation has injected new vitality into the environmental protection education of Hongguang primary school.

Hongguang primary school's environmental protection education is impressive, and Yingshan County hope middle school has also implemented environmental protection education. In the "3R environmental protection bank" of the school, various school supplies and sports equipment are neatly displayed. According to Yi Bo, the president of the school, in order to enable students to actively participate in environmental protection practice, each class will exchange the collected waste paper and plastic bottles into points in the "bank". When the points reach a certain amount, they can be exchanged into favorite school supplies and sports equipment in the "bank".

"This' environmental bank 'has not only cultivated students' awareness of environmental protection, but also helped them form a good habit of diligence and thrift. After years of practical education, the children's concept of environmental protection has become a kind of action consciousness." Yi Bo said.

In rural areas, the awareness of environmental protection is also deeply rooted in the hearts of the people. On June 17, uncle Luo of Fengtou village, wanglonghu town bundled the dried wheat straw one by one and transported it to Yingshan Xinqiao cattle raising professional cooperative for sale.

"In the early years, we stopped burning straw. In addition to smashing it and using it as fertilizer, we sold the rest, which can not only be used to subsidize the household, but also protect the environment, killing two birds with one stone." Uncle Luo said with a smile.

According to Zhang Li, head of the asset and environment unit of Yingshan agricultural and rural Bureau, there are 35 straw collection and storage centers in Yingshan County, such as Yingshan Xinqiao cattle raising professional cooperative. In addition, there are two large straw collection and storage centers in Dongsheng and lingjiu towns. Those large farmers transport their straw to the collection and storage center for sale every crop harvest season.

It is understood that Yingshan County has established a sound straw collection, storage and transportation system, and set up temporary straw collection and storage points beside the roads with convenient transportation. After the crops are harvested, farmers consciously transport the straw to these temporary collection and storage points. Yingshan County Comprehensive Administrative Law Enforcement Bureau regularly transports and treats the straw at the collection and storage points, effectively avoiding the atmospheric pollution caused by straw incineration.

"Ecological and environmental protection is a long-term and arduous task. The" five entry "campaign of environmental protection publicity" into schools, communities, rural areas, enterprises and families "has made everyone deeply aware of caring for the environment and protecting the environment. We will adhere to the concept of green development, continue to consolidate and expand the achievements of ecological construction, enhance the background of ecological and livable homes, make the sky bluer, mountains greener and water cleaner in Yingshan, and let the people share more ecological benefits," said the relevant person in charge of Yingshan County Government.
