In autumn, Yuzhidian Village, located in Huangpi District, Wuhan City, has clear water like a mirror and distant mountains like Dai. The murmuring clear water flows continuously into the small river in front of the village through the ditch. This beautiful scenery is thanks to the largest rural domestic sewage treatment project in Hubei Province - the Huangpi District Rural Village Domestic Sewage Treatment Project in Wuhan City. The project covers over 2000 natural villages in Huangpi District, benefiting approximately 120000 households. It has recently passed acceptance and the first batch of treatment facilities have been put into operation. In the past, villagers' domestic sewage was directly discharged into the river, causing the river to become foul smelling and mosquitoes and flies to breed. "Gong Guangyin, Deputy Secretary of the Party Branch of Yuzhidian Village, said that now the sewage from each household flows into sewage treatment facilities through the pipeline network, and is treated centrally before being discharged." The water is cleaner, the river and pond are clearer, and the living environment is significantly improved. "The reporter saw a clearing full of green grass by the river, surrounded by a fence, The lush greenery blends with the surrounding rural scenery. There are several neatly arranged manhole covers on the grass. When the covers are opened, the sound of water is loud and the water is flowing into the underground installation. This is actually a buried domestic sewage treatment facility below, "said Yu Huiguo, the head of the Huangpi District Rural Village Domestic Sewage Treatment Project of China Construction Third Bureau. The sewage generated by each household in the village first enters the grid well for filtration, and then enters five treatment tanks, including pre fermentation tank, anaerobic tank, and facultative tank. After a series of biochemical reactions such as hydrolysis, acidification, adsorption, and metabolism, it meets the discharge standards. The treated water meets the first level standard for water pollutant discharge from rural domestic sewage treatment facilities in Hubei Province, and can be directly used for farmland irrigation, "said Yu Huiguo. It is reported that the project has built nearly 600 centralized sewage treatment facilities. The construction plan is tailored to local conditions, using buried integrated equipment in village bays with relatively flat terrain, while using aboveground integrated equipment in village bays with large elevation differences and rocky geology. After greening and renovation, these sewage treatment facilities are integrated and complement the construction of beautiful rural areas. The project has also built over 50000 decentralized sewage treatment facilities in smaller villages, with over 1800 kilometers of sewage pipelines connecting tens of thousands of treatment facilities of all sizes, forming a huge sewage treatment network. In order to operate such a huge sewage treatment system well, each sewage treatment facility is equipped with sensors, and various operating data is displayed in real-time on the large screen of the project operation management platform. Once a fault occurs, it will automatically alarm, and at the same time, it can also achieve one click remote control. The operation and maintenance challenges of a large number and scattered distribution of rural sewage treatment facilities can be easily solved with the support of industrial internet technology, cloud technology, and other technologies, "said Yu Huiguo. Huangpi District, Wuhan City has a national 5A level tourist attraction called Huangpi Mulan Cultural Ecological Tourism Zone. During the recently passed Mid Autumn Festival holiday, a large number of tourists came to visit. The environment is getting better and better, and many villagers who work outside have returned to the village to open homestays, develop leisure agriculture, and their income has also increased, "Gong Guangyin said.
