Method for preventing and treating regional farmland non-point source pollution through farmland ditch and pond system
The invention provides a method for preventing and treating regional farmland non-point source pollution through a farmland ditch and pond system. According to the method for preventing and treating the regional farmland non-point source pollution through the farmland ditch and pond system, an ecological pond is added to a farmland irrigation and drainage ditch based on arrangement and improvement of the farmland irrigation and drainage ditch according to a farmland surface runoff confluence track, the water flow speed of the farmland ditch is rapidly slowed down, the buffering capacity of a farmland system against water is reinforced, the cycle efficiency of farmland interior water sources and nitrogen and phosphorus nutrients is improved, the farmland non-point source sewage discharge is reduced, farmland nitrogen and phosphorus pollutant discharge is effectively cut down, and the method plays a greater role in protecting regional water environment.
