Haikou: The application of the system of "four grassroots" in the rectification of black and odor-smelling water bodies in rural areas

The formation of black and smelly water bodies in rural areas is mainly due to the untreated direct discharge of domestic sewage, livestock and poultry breeding wastewater, excessive use of pesticides and fertilizers, which leads to the deterioration of water quality and the formation of black and smelly water bodies. This phenomenon not only seriously affects the rural ecological environment, but also has a serious impact on the quality of life of farmers. Haikou City government attaches great importance to this problem. They understand that in order to completely solve the problem of black and odorous water bodies in rural areas, scientific, reasonable and practical measures must be taken to control them. To this end, Haikou City in May this year launched the Qinshan village black and smelly water treatment pilot project. Carry out a comprehensive investigation of the city's rural black and smelly water bodies, and formulate a detailed remediation plan. Up to now, the city has completed the treatment of 16 water bodies, including 7 water bodies included in the national regulatory list. According to the plan, 35 rural black and odorous water bodies will be completed by the end of this year; By the first half of 2024, 68 black and odorous water bodies in rural areas will be controlled.

The formation of black and smelly water bodies in rural areas is mainly due to the untreated direct discharge of domestic sewage, livestock and poultry breeding wastewater, excessive use of pesticides and fertilizers, which leads to the deterioration of water quality and the formation of black and smelly water bodies. This phenomenon not only seriously affects the rural ecological environment, but also has a serious impact on the quality of life of farmers. Haikou City adopts the idea of pilot first and steady progress in governance, and launched the pilot project of black and smelly water treatment in Qinshan Village in May this year. The treatment contents include the removal of livestock and poultry breeding sites around the water body, site leveling, source control and pollution interception, drainage and ecological restoration, etc. After the implementation of these remediation measures, the black and smelly water bodies in rural areas have been effectively treated. The water quality has been significantly improved, and all indicators have reached the testing standards. The quality of life of the local population has improved.



Use the "four grassroots" system to promote the rectification of black and odorous water bodies



Haikou City government uses the "four grassroots" system to introduce an innovative measure for the rectification of black and odorous water bodies in rural areas. The system devolves the focus of work to the grass-roots level, and through going into villages, farmers, fields and ditches, understanding the needs of the masses, mastering the actual situation, and promoting policies and technologies to take root at the grass-roots level. We will coordinate efforts to control black and odorous water bodies in rural areas. In the process of implementation, Haikou City first conducted a comprehensive investigation of the city's rural black and smelly water bodies. The staff went into the village, communicated with the villagers, understood the water pollution situation, and recorded it. According to the investigation results, Haikou City formulated a detailed remediation plan.



Members of the Haikou leading team went deep into the grassroots to understand the actual situation of black and smelly water bodies in rural areas. They inspected the water conditions in rural areas, communicated with local villagers and listened to their opinions and suggestions. Through in-depth investigation, leading cadres have mastered first-hand information, which provides strong support for the subsequent rectification work. According to the results of the investigation, the Haikou municipal government formulated a detailed remediation plan. The plan defines the objectives, tasks and measures for the management of black and odorous water bodies in rural areas. At the same time, the municipal government has also increased the investment in governance work, increased the investment of governance funds and personnel, and ensured the smooth progress of the renovation work.



Strengthen supervision and management of livestock and poultry breeding



The agricultural and rural departments of Haikou assigned the supervision and inspection work of livestock and poultry breeding to all districts of the city, strengthened supervision and management, and linked the free-range livestock and poultry breeding with the assessment of rural living environment. Through the implementation of the comprehensive utilization project of livestock and poultry waste in Haikou City, the whole county promotion project of the utilization of livestock and poultry waste resources in Qiongshan District, and the auxiliary construction project of the harmless waste treatment facility of Wenchang Chicken advantageous industrial cluster, the effective treatment and utilization of livestock and poultry breeding waste are promoted. At the same time, improve the harmless treatment system of sick and dead livestock and poultry, and effectively reduce pollution emissions of livestock and poultry waste.



Up to now, the city has completed the treatment of 16 water bodies



According to the latest data, Haikou City has identified a total of 74 black and smelly water bodies in rural areas, completed 31 rural domestic sewage treatment natural villages, a total of 3,394 sets of equipment, a total investment of 205 million yuan, and the construction of a pipe network length of 16 kilometers. Behind these figures is the Haikou municipal government's firm determination and practical actions on environmental protection. According to the plan, 35 rural black and odorous water bodies will be completed by the end of this year; By the first half of 2024, 68 black and odorous water bodies in rural areas will be controlled. Up to now, the city has completed the treatment of 16 water bodies, including 7 water bodies included in the national regulatory list.



Adjust and optimize the plan according to local conditions



The dispersion of living in rural areas makes the collection and treatment of domestic sewage difficult. The complexity of terrain makes the laying and maintenance cost of pipe network greatly increase. The imperfect drainage facilities make rainwater and sewage often mixed together, which brings more difficulty to treatment. The low efficiency of the treatment process means that more resources and manpower are required. Despite the difficulties, Haikou's efforts have not been in vain. They have successfully remediated many black and smelly water bodies in rural areas and achieved remarkable results. The water quality has improved markedly, and the number of aquatic life has increased a lot. This not only improves the quality of life in rural areas, but also protects the ecological environment.
