Method for preventing and treating mountainous and semi-mountainous area rural non-point source pollution through ecological ditch and pond system
A method for preventing and treating mountainous and semi-mountainous area rural non-point source pollution through an ecological ditch and pond system comprises the following steps of firstly determining the actual area, the population, the breeding number, a surface runoff coefficient and a surface hardening coefficient of a village residential area; determining the sewage output of the village residential area; secondly transforming draining canals of the village residential area to enable the village residential area to be provided with only one water outlet; thirdly constructing a sewage flow dividing device, a homogenizing adjusting device and a harmless processing device at the sewage outlet of the village residential area. According to the method for preventing and treating the mountainous and semi-mountainous area rural non-point source pollution through the ecological ditch and pond system, systematic improvement is performed based on original natural ditches of mountainous and semi-mountainous area villages, and source collection, homogenizing adjustment and innocent treatment of the non-point source sewage of the villages are achieved, and the non-point source sewage enters downstream rivers and lakes after being utilized in the farmland, and influences of the mountainous and semi-mountainous area rural sewage on water bodies are effectively reduced.
