The process of ecological environment changes in Pujiang River

The process of changes in the ecological environment of the Pujiang River is as follows:

Before the water control, by the end of 2012, Pujiang had 22,000 factories and family-style crystal enterprises, employing more than 200,000 people. 13,000 tons of crystal wastewater and 600 tons of crystal waste residue are produced every day and are discharged without effective treatment, resulting in solid waste everywhere and sewage flowing across the ground. The polluting industries represented by the low-end crystal industry not only enriched the people, but also pushed the ecological environment of the Pujiang River to a desperate situation.

Of the 577 large and small rivers in the county, 90% have become milk rivers, garbage rivers, and black and smelly rivers. "Sitting on the garbage heap counting money, lying on the hospital bed spending money" is a true portrayal of Pujiang's abnormal development at that time.

In the early stage, there were 2,624 "Operation Clear Water Zero Points", closing 5,500 illegally discharged direct discharge processing households; 4,672 "Operation Golden Sunshine", closing 9,100 unlicensed and unlicensed processing households; 942 "Fire Control Operations" "Safety Improvement", 1,800 processing households with safety risks were closed; 21,520 polluting crystal processing households were shut down; 23 dyeing, papermaking, and electroplating enterprises were shut down and transferred; 360 illegal processing points such as waste plastics and lead-acid batteries were banned in accordance with the law. More than one.

754 farms in the "prohibited breeding areas" were shut down, and all farms in non-prohibited breeding areas achieved zero wastewater discharge and full utilization of waste.

The Xiaohuangtan landfill that has been delayed for 8 years took only 10 days to complete the land acquisition, two months to complete the preliminary approval, and ten months to complete and put into use; the "Sanjiangkou" ecological comprehensive improvement project was centralized It integrated the functions of pollution, flood control, drainage, environment beautification, leisure, and ecological conservation. It only took 30 days to complete the construction. The "garbage dump" was transformed into an "ecological park", creating the "Sanjiangkou Speed" in the history of Pujiang water conservancy.

The Fourth Sewage Treatment Plant completed site selection, project establishment, approval, and land acquisition in just 57 days, creating the fastest approval time for similar projects in the province; the Jinshi Lake Old Town Renovation Project covering an area of ??2,500 acres , it only took 12 days to complete the signing of the first phase of 750,000 square meters of relocation. The "big dye vat" of the year has now been transformed into a "Little West Lake"; the famous "Black and Smelly Lake" Green Lake has been renovated in less than a year. Become a "natural swimming pool".

In 3 years, all black and smelly rivers and milk rivers were eliminated, creating the first batch of non-illegal counties and the first batch of beautiful rural demonstration counties in Zhejiang. The total number of petitions dropped significantly, from a national petition county to a national petition county. An advanced county, achieving the "seventeenth consecutive championship" of Ping An Pujiang. It has been praised as the "Dayu Ding" of Zhejiang Province for eight consecutive times. It won the 10th "China Environment Award" and was awarded by former United Nations Deputy Secretary-General Solheim. Praise is what China and even the world will look like in the future.

The county’s 462 “milk rivers”, 577 “garbage rivers” and 25 “black and smelly rivers” have been completely eliminated. The water quality of 51 tributaries has all reached or better than Class III. Puyang River is happy The section (Cuihu) was the first to be recognized as a "swimable river section" by the Provincial People's Congress, becoming one of the first counties in the province to meet the "Three Clean Rivers" standards; it has completed the task of "resolutely eliminating inferior Class V and Class V water, and basically eliminating Class IV water" The first batch of national ecological civilization construction demonstration counties were successfully created.

Today, the water quality of the outbound section of the Puyang River has been improved from worse than Class V to Class III for 8 consecutive years. The water quality of the entire county’s waters has reached Class III and above. In the Puyang River water biodiversity survey, it was found that high quality Water quality indicator organisms - EPT insects, this is the first time in Zhejiang Province's water environment improvement effect investigation.

At the end of 2022, the administrative village coverage rate was 89.27%, the water quality compliance rate was 82.62%, and standardized operation and maintenance achieved full coverage. It won the honorary title of "Excellent County in Rural Domestic Sewage Treatment in Zhejiang Province" for the sixth time, and "Rural Domestic Sewage Treatment" "Digital Intelligent Processing System" was included in the province's "One City, One Model" cultivation list.

In 2022, the water quality of Jinkengling Reservoir, the county-level drinking water source in Pujiang, will reach Class I, and the 10 Puyang River and Huyuan River main stream sections and 51 tributaries will all reach or be better than Class III, with a compliance rate of 100 %, the assessment result of Pujiang County handover section is excellent.

Transformation and upgrading of traditional industries. Invest 2 billion to establish four modern crystal industrial parks to achieve "park agglomeration, unified pollution control, and industrial improvement." At the same time, we will use factory roof resources to integrate power grid construction, new energy technology, digital transformation, etc., and promote large-scale photovoltaic demonstration applications in the park. Helping achieve carbon peak and carbon neutrality goals, it can save nearly 1.2 million yuan in electricity bills every year and reduce carbon emissions by more than 3,000 tons.

In the past, the crystal-polluted villages Shanghe Village and Xinguang Village are now internet celebrity check-in spots, traditional Chinese villages and famous historical and cultural villages in Zhejiang Province... The perfect transformation of the countryside is just the result of Pujiang's further promotion of the "Five Waters ***" The epitome of the effectiveness of "governance". B&Bs such as the Yuzhai Xiyin Shanfang built near the water, the Qianwu Bushe Yema Ridge in the secluded area, the Zhengzhai Qingzhiwulu with small bridges and flowing water, and the Xianhua Shili Pine Room in the countryside have sprung up among the green mountains and beautiful waters.
