Description
Technical field
This utility model relates to a kind of water body purification system, in particular, relates to a kind of renewable filler-plant society formula irrigation canals and ditches bank protection nitrogen phosphorus ecological intercepting system.
Background technology
China's fertilizer application amount occupies first place in the world, but the utilization rate of chemical fertilizer is very low, chemical fertilizer be excessively used and Fertilization Structure unreasonable causes that fertilizer runs off in a large number in rainfall with after irrigating, the runoff containing a large amount of nitrogen phosphorus nutrients is directly discharged into river course or lake, defines the serious threat to body eutrophication.Research shows, TAIHU LAKE eutrophication problem and widespread pollution from the overuse of fertilizers and pesticides in rural area have direct relation.Widespread pollution from the overuse of fertilizers and pesticides in rural area has become one of primary pollution source of China's water pollution, and Control the Plan Pollution Sources has arrived instant stage.
The domestic research about pollution of area source is by the eighties in 20th century, such as mountain region, basin, East Lake, Wuhan City and region, farmland nitrogen and phosphorus loss, the agricultural nonpoint source pollution of Taihu Lake, Jiangsu and control way research thereof etc..At present, the pollution of area source control engineering that China is common, mainly include plant buffer strip, artificial wet land system, multi-pond system, ecological canal system etc., utilize the vegetation absorption interception capacity to soil nutrient, it is achieved retaining and filtering area source pollutants.In Process of Engineering Construction, combine closely with the view of surrounding, only effectively do not cut down Rural Plane Source Pollution load, it is possible to improve rural environment view to a certain extent.
Agricultural area source pollutants is had good purification by ecological canal, is the technological means effectively controlling widespread pollution from the overuse of fertilizers and pesticides in rural area being suitable for China's national situation and region feature.China's farmland ditch is numerous and comparatively unified, builds up if, with existing farmland ditch and has the ditch wetland intercepting function, will can reduce the risk of Agricultural land loss N, P entrance water body.But when heavy rain occurs, irrigation canals and ditches displacement is big, hydraulic detention time is short, the absorption interception result of nitrogen phosphorus will significantly be declined by ecological canal, cause that a large amount of high concentration agricultural drain is directly entered river course or enters follow-up unit for treating water, cause the pollutant burden of river course or follow-up unit for treating water to increase substantially.How to ensure to reduce the concentration of nitrogen and phosphorus pollutants before storm runoff enters river course, become the problem being presently required urgent solution.
