Study On The Pattern And Treatment Of Rural Domestic Sewage In Jiangxi Province

At present,there are about 16,000 administrative villages and 169,000 natural villages in Jiangxi Province,which annually dispose of about 270 million tons of rural household life and industrial waste.The problem of pollution from unconventional sources caused by the dumping of rural domestic sewage is becoming more serious.Human and animal feces and urine in internal sewage High fluid content and high nitrogen and phosphorus content,especially phosphorus content.Insufficient attention from relevant departments,low investment in governance and poor public awareness of rural environmental protection and other factors have affected the process of sewage treatment in rural Jiangxi.In this paper,taking the new rural construction village with relatively concentrated sewage collection as the pilot,the status quo of water environment in Jiangxi Province was investigated,and the types,substrates and vegetation of constructed wetland suitable for domestic sewage treatment were compared and analyzed.The constructed wetland ecological engineering was constructed to treat the domestic sewage centralized,and the village ponds within the scope of the new rural area were renovated,and probes into the changing characteristics of rural population and the trend of rural living pollution.This sewage treatment mode can effectively treat the rural sewage related to surface runoff and rainwater scouring,and can make up for the defects of centralized treatment mode through decentralized treatment mode,mainly according to the characteristics of sewage,the actual situation of the village and the requirements of the effluent,combining the characteristics of the existing sewage treatment technology,the main contents are the treatment of centralized domestic sewage and the treatment of decentralized domestic sewage.The treatment scheme of no-power constructed wetland and oxidation pond is adopted,at the same time,the policy protection measures are put forward.
