Ecological treatment technology for agricultural non-point source pollution in remote rural areas of China

Agricultural non-point source pollution is one of the important reasons for rural water pollution, and it is also an important source of water eutrophication. In recent years, with the rapid economic growth and social changes in rural areas, large amounts of untreated domestic sewage and agricultural wastewater entering farmland require high efficiency, low operating costs, and minimal maintenance of treatment systems in rural and remote areas to minimize their impact on water and biodiversity. Since there is little research on the ecological treatment technology of agricultural non-point source pollution in China, from the perspective of controlling agricultural non-point source pollution, some ecological treatment technologies suitable for rural areas at home and abroad are summarized. This paper introduces the practical application of ecological treatment technology, the type of process, advantages and disadvantages, and the influencing factors of ecological treatment technology in the purification of sewage engineering and summarizes the removal mechanism of pollutants in ecological treatment technology. Eco-processing technologies are cost-effective in terms of their construction, maintenance, and energy needs and can be considered a sustainable wastewater treatment method, especially in remote areas and developing countries. It provides basic ideas for the construction of rural ecological treatment technology in China and puts forward suggestions and ideas for the future development trend of ecological treatment process sewage.
