Ecological circulation system for treating farmland non-point source pollution
The invention discloses an ecological circulation system for treating farmland non-point source pollution. The system comprises a symbiotic farmland, a water collecting tank, an ecological interception ditch, an artificial wetland and an ecological purification pond which communicate in sequence; and the symbiotic farmland comprises an annular outer ridge, an annular inner ridge and a planting field, the planting field is located in a ring of the inner ridge, the inner ridge is located in a ring of the outer ridge, a fish ditch is arranged between the inner ridge and the outer ridge, a fish channel is arranged between the fish ditch and the planting field, and the fish ditch communicates with the water collecting tank. The ecological circulation system adopts the symbiotic farmland to reduce the use of pesticides and fertilizers from the source, and adopts the water collecting tank, the ecological interception ditch, the artificial wetland and the ecological purification pond to further treat sewage in the diffusion process of pollutants, so that the treatment effect of the whole ecological prevention and control system is improved.
本发明公开了一种处理农田面源污染的生态循环系统，包括共生农田、集水池、生态拦截沟渠、人工湿地和生态净化塘，所述共生农田、集水池、生态拦截沟渠、人工湿地和生态净化塘依次连通；所述共生农田包括环状的外田埂、环状的内田埂和种植地，所述种植地位于内田埂的环内，所述内田埂位于外田埂的环内，且所述内田埂与外田埂之间设有渔沟，所述渔沟与种植地之间设有鱼类通道，所述渔沟与集水池连通。此生态循环系统采用共生农田从源头上减少农药和化肥的使用，减少农药和肥料的使用，同时在污染物的扩散过程中，采用集水池、生态拦截沟渠、人工湿地和生态净化塘进一步处理污水，从而提高了整个生态防治系统的处理效果。
