Method for preventing and treating plain river network area farmland non-point source pollution through channel and pond system
The invention discloses a method for preventing and treating plain river network area farmland non-point source pollution through a channel and pond system. According to the method, on the basis of the original irrigation and drainage channel and pond system of a plain river network area, according to the distribution situation and the elevation of the farmland area channel and pond system, all single bodies and facilities are tightly connected together according to the functions through ecological channels, a pond at the highest position serves as a farmland irrigation water pre-treatment pond, a pond at the lowest position serves as a water yield and water quality comprehensive balance regulating and controlling station, water in the low-position pond is lifted to the high-position pond, a channel and pond purification system in multi-stage series circulation is formed, water level control gates are arranged at key positions of the whole channel and pond circulation system, the residence time of water in farmland in the system is regulated and controlled, the migration path of pollutants is prolonged, the purposes of reducing the outer drainage amount and fully utilizing nitrogen and phosphorus are achieved, farmland non-point source pollution can be effectively relieved, and a huge role is played for protecting the plain river network area water environment.
