With the rapid development of my country's social economy, the continuous advancement of new rural construction and the process of small urbanization, the pollution of rural water environment has become increasingly prominent. In recent years, the discharge of rural sewage in my country has increased at an annual rate of 15%. Among the 2,200 county towns and 19,200 organic towns, sewage discharge accounts for more than half of the total national sewage discharge, while the current centralized treatment rate of rural sewage in my country is only about 0.5%, and more than 99% of the country's rural sewage has not been treated effectively. The collection and treatment are directly discharged to the nearby water bodies, resulting in a sharp drop in the water quality and even the loss of its function as water for industry and agriculture. This situation not only seriously affects the living environment of farmers, but also seriously affects the process of new rural ecological construction.
