Drip washing enters water bodies of rivers and lakes.This by the widespread pollution from the overuse of fertilizers and pesticides in rural area that agricultural run-off causes also become environmental pollution key factor it
One.
No matter for urban runoff or agricultural run-off, based on the laying of extensive rain sewage network and farmland ditch construction
Product collection system of confluxing build comparative maturity.But in terms of producing the process after collecting of confluxing, urban runoff Environmental capacity mesh
Front main purify early-stage rainwater pollution by building pretreatment facility come emphasis, Farmland Flow Pollution then passes through to build artificial swamp
Processed etc. Ecological Disposal facility.But this treatment facility generally requires to take fairly large land resource, is difficult
Implement, and invest huge.
