Cast urban water system, promote water environment rectification, Anhui Anqing – Water Qing’an Green Yicheng Yiju (Xiaocang Road on Green Power) Anhui Anqing City, Don’t call "Yicheng", there are 10 lakes 46 rivers, the rivers and lakes are 225 square kilometers, accounting for25% of the total local area.
Water is the characteristics of Anqing, but also the valuable resources of Anqing, but the water environment here is very "troubles".Renovation of black odor, strengthen law enforcement supervision, build a lake wetland, open the urban water system … In recent years, Anqing has included all lakes and rivers into governance, gradually constructing a ecological water network.
Today, all the water systems in Anqing City run, "Yicheng" has also become more livable.
The water is connected, the water is still active, and it is an important river connected to the Anqing Old Town and the New Town.
Today, more than a dozen ponds along the river, the pool is crystal clear, and the water swaying the reeds, and the lily. However, the initial plan is not the case.
Li Jun, a residential department of the housing project, the construction of the key project, and participated in the whole process of comprehensive management of the new river.
He recalls that these ponds earlier are fishing ponds. They have professional institutional planning, and they will fill them with these ponds, widen, harden, and river. But later, Anqing City vetoed this design.
At the end of 2015, Anqing hired a professional team led by the Institute of Environmental Sciences, the Ecological Environment Department, with a focus on water ecological environmental protection, and launched a resident tracking study to provide scientific recommendations for precision pollution.
At the same time, it is integrated with rainfall, intercepting vessels, shoreline repair, ecological dredging and other projects. Since 2016, Anqing has built 450 kilometers of sewage pipes and 76 rainwater pipelines, investigating 1864 water pollution problems, and 8 new ends of the new end. Open the distribution map of Anqing ecological water network system, clearly see that there are different lakes in the north and south of East and West. Among them, "a lake Jiuhe" is a pen. "One Lake Jiuhe" refers to the nine rivers, Bai Zhuhu and including Huaihu River, and Qinquan River. "One Lake Jiuhe" governance project started in April 2017, governing the lake area square kilometers, the length of the river, with a landscape green area of ??about 10,000 square meters.
Through the implementation of the project, Anqing City connects all the rivers and lakes, forming two water-based aorta – the main rivers of the main river and the main rivers of the main rivers and the main rivers of the Eastern North and South, and eventually connected the Yangtze River. The water is connected, and the water is still active. "In the process of comprehensive management of water, there is a lot of problems such as the black stink, river sedimentation, and insufficient drainage capacity, because the water flow is not smooth, let the water flow, it is an inevitable requirement of ecological pollution.
Jiang Kuitang, Party Secretary of Anqing Ecological Environment Bureau, Director Jiang Kuitang, said. By running through the entire urban water system and connects to the Yangtze River, from the two-wire water supply of the Yangtze River and Shitang Lake, the daily hydration of Anqing City is 300,000 tons, which solves the flooding. Drainage demand, which solves the problem of environmental pollution caused by broken head.
The investment is fine, the effect is not discounted to the winter of Shitang Lake, along the coast of grass, although the reed is a little yellow, but the lake is blue, the mountain lake is reflected, still the scenery.
Here, it is an alternate water source in Anqing. In order to improve the water quality of Shitang Lake, Anqing’s 980,000 square meters of fish ponds in Tong retreat, the daily purification capacity reached 10,000 tons. Liu Gang, deputy manager of Shitang Lake Project, said the water flowing upstream through the gate, introduced into the pretreatment zone, and the preprocessing zone is connected to the net water channel, and the water flows into the table flow through the clean water.
The surface flow and wet areas are serially connected in series with aquatic plants and the sultime, through a variety of aquatic plants and microorganisms, the common effects of soil, and the functions of wetland interception, purification and other functions. The water flowing from the surface flow wet area enters the depth purification area, and the area is used to store purified water, and the other hand is further purified by aquatic plant to stabilize the water quality.
In addition, the complete ecological purification system is formed by reasonably configured the seasons of evergreen plant communities.
"This project officially started in 2019, and ended in the second half of 2020." Liu Gang said, now, the stone lake, the water quality has reached Class III standard. In many projects in water environment governance, Anqing is based on ecological management as a concept, and the cost is low, and the cost is low.
According to Li Jun, Xinhe retains more than a dozen ponds, only one, saving at least 30 million yuan investment.
Although it is finely calculated in investment, the effect is not discounting.
Take the "one lake Jiuhe" as an example, the current water quality has increased to class standard, and the water quality of the Qing Dynasty water country control section is 100%. The two section water quality of the Yangtze River is in the class, the city surface water is basically eliminated. V.
In the rectification of the new river, there is no plan for the initial filling of the pond and hardened roads, but planted the riverside, 660,000 square meters of flowers, 540,000 square meters of lawns and 10,000 square meters of aquatic plants, let it It became a local well-known green ecological corridor.
Will fully promote rural sewage remediation in Anqing, many rivers have experienced the changes in the new river. In the winter, the artificial buoy in Hunting River is still lush. But many years ago, Hunting River was a famous "stink". "Hunting River has grown again and smelly, after governance, also raise the fish, the floating island is still a lot of flowers, very beautiful, and very comfortable nearby.
Huang Industry, Hunting North Village, Grand View District, Anqing City.
After a targeted comprehensive rectification, Anqing size river lake is new.
Li Jun said that he also wanted to understand that if many areas can make a lot of money, why should you stay for environmental rectification? But now he understands. "Next, we will continue to focus on the in-depth governance of key pollution sources, and further enhance existing urban industrial governance standards.
At the same time, we will fully promote the pollution control of agriculture, through the adoption of local conditions, the rural sewage rectification is fully promoted as the next work. "Jiang Kuitang said.
Wei Xiaoming, secretary of the Anqing Municipal Party Committee, said that Anqing will continue to grasp the key projects such as rivers and lake governance, one hand to grasp the innovation of institutional mechanisms such as Lin Changzhi, the Heavy System, and Lake, and promote the continuous improvement of ecological environment.
