Shanghai -Yunnan Cooperation This project benefits nearly 100,000 people in Laoshan County, Yunnan.

In the midsummer, walk into the Luther Village Committee of Jianga Town, Tana Town, Wenshan, Wenshan Zhuang Miao Autonomous Prefecture. The local people live in the mountains and rivers according to the mountains, and the sewage pipelines in the village connect each household. The villages are clean and tidy, the environment is beautiful, and the ecological livable.

Luther Reservoir, 7 kilometers away from Laoshan County, is one of the sources of drinking water in nearly 100,000 residents in Laoshan City. It is located in the surrounding area of ​​Luther Village, Xiaoshui well, and Laile. Over the years, due to the lack of comprehensive sewage pipelines, daily rural sewage discharge at will, not only the environment is messy, but also pollutes the water source, affects the safety of drinking water in urban residents. The Shanghai -Yunnan cooperation platform actively strived for financial support and implemented the sewage treatment project around the villages around the Luther Reservoir.

"According to the characteristics of the decentralized distribution of farmers' houses, the project adopts a decentralized treatment system to set up a total of 18 sewage treatment points." Wang Weihong, general manager of Shanghai Fuao Construction Technology Co., Ltd. The investment is too high, and its sewage can be discharged on the standard with the combined purification tank. A total of 70 purification grooves and 70 sedimentation collection ponds are constructed in three village groups, 338 rainfalls in the households are transformed , 9,147 meters of sewage pipelines, 4,543 meters of sewage distribution pipelines, to achieve all farmers' domestic sewage treatment.

Yunnan belongs to the provinces of mountainous areas, and the people in the mountains are relatively scattered. In Wang Weihong's view, the project adopts various forms of segments, single households or multiple households, and sewage collection and treatment, which fully reflects the characteristics of decentralized sewage treatment technology, and plays an important role in pollution control. "Choose the rural sewage treatment model that conforms to the development and characteristics of various places, do a good job of decentralized sewage treatment according to local conditions, but also the beautiful and neat environment of the people, and protect the green mountains and green mountains." Wang Weihong said.

In order to solve the problem of daily electricity consumption system of the sewage treatment system, the project supports the grid -connected solar photovoltaic power generation system and adopts 540W high -efficiency single crystal silicon photovoltaic component. The reporter saw in an interview with the Luther Village Committee that a solar photovoltaic power generation system was built on roofs and parking sheds of the village committee. "The total paving area here is 1,000 square meters. Building photovoltaic power generation, the benefits are two birds with one stone." Wang Weihong told reporters while pointed at the solar photovoltaic power generation system that it is expected to be 250,000 kilowatt -hours of power after completion. The annual power consumption, the remaining 190,000 kilowatt -hour merged into the Southern Power Grid, provided a guarantee for the subsequent operation of the project, and also increased the village collective income.

In the Xiaoshuijing Village Group, there are several connected surface flow wetlands. By building a multi -level sedimentation, filtering, and ecological purification pool to remove aquatic weeds and floating garbage, build a slag steel mesh between the wetland and the reservoir, plant aquatic planting aquatic Plants, further reduction of agricultural surface source pollution to reservoir emissions. "Through the buffer of the wetlands, the excess nitrogen and phosphorus in the water are deposited in the soil in the form of particles. In addition, the root system in the wetland is absorbed by the impurities in the water again. So as to purify downstream water quality and improve the purpose of the ecological environment. "Wang Weihong introduced.

The implementation of the sewage treatment project of the Luther Village Committee effectively solves the situation of the poor and messy situation of Luther Village Committee, improves the production and living conditions of the masses in the village, and promotes the overall improvement of the village appearance. “这个项目做得非常好，以前村里生活污水乱排放，污水到处流，通过统一排放后，现在变得干净了。”目睹村里环境卫生由脏乱差变为洁净美，小水井村小组村民陆Xiangxi laughed and opened her thumbs frequently.

After the completion of the sewage treatment project of the Luther Village Committee, the source water quality can be effectively controlled, protecting the reservoir ecosystem, and ensuring that the water quality of Luther Reservoir has been maintained in the second category for a long time.

Rural sewage treatment is an important part of the improvement of rural human settlements and an important measure to implement the strategy of rural revitalization. In recent years, Shanghai -Yunnan cooperation has actively explored the new path of sewage management in the rural areas of Wenshan, innovative governance models, strengthened operations and maintenance, and helped make up for the shortcomings of the living environment, and accelerated the construction of beautiful and livable villages.
