The invention discloses a contiguous farmland non-
point source pollution control system, which comprises an ecological
ditch, a water-logged
compost pool, a
fertilizer liquid collection
pool and a deep adsorption
bed, and is characterized in that the ecological
ditch is arranged in a farmland, and is used for collecting rainwater in the farmland and filtering and adsorbing part of pollutants in the rainwater; the water-logged
compost pond is communicated with the ecological
ditch, the ecological ditch is used for conveying part of rainwater to the water-logged
compost pond, and the water-logged compost pond is used for water-logged compost by utilizing rainwater and agricultural wastes; the
fertilizer liquid collecting tank is communicated with the water-logged compost tank and is used for collecting
fertilizer liquid generated by the water-logged compost tank; the deep adsorption
bed is communicated with the ecological ditch, the ecological ditch is used for conveying residual rainwater to the deep adsorption
bed, and the deep adsorption bed is used for adsorbing pollutants of the rainwater. The multi-stage interception mode of the ecological ditch, the water-logged compost
pool and the deep adsorption bed is adopted, the effect that soluble pollutants are adsorbed, absorbed and reused is achieved,
solid pollutants are subjected to resource reutilization, and
zero emission of farmland pollutants is achieved.
