The invention discloses a compound ecological system for agricultural non-point source pollution treatment, and relates to the technical field of environmental engineering, the compound ecological system comprises an ecological pond, a ditch, an ecological dam and an ecological floating bed, the joint of the ecological pond and the ditch is provided with a permeation well, the ecological dam is a stepped dam, and the pond water in the ecological pond is provided with the ecological floating bed. The compound ecological system has the beneficial effects that different planting areas are arranged at the bottom of the ecological pond and on the ecological dam according to the growth environment of the planted plants, the planted products are preferentially selected, the planted plants absorb and purify pollutants such as nitrogen and phosphorus in water, meanwhile, good growth of the planted plants is guaranteed, and the agricultural production income is increased.
Description
technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a composite ecological system for controlling agricultural non-point source pollution. Background technique [0002] The formation of agricultural non-point source pollution is a comprehensive process, which is affected by many factors such as soil, terrain, precipitation, land cover, and human activities, mainly including soil nutrient content, external nutrient (chemical fertilizer, organic fertilizer, etc.) Poultry farming, etc. Agricultural non-point source pollution causes nitrogen, phosphorus and other pollutants on the soil surface or in the soil to migrate to surface water and surface water, which is one of the main reasons for surface water eutrophication or groundwater nitrate pollution. Agricultural non-point source pollution needs to be treated urgently. In view of the existing water storage and pollution reduction management model, the pond and wei...
