The current pollution status and control technology of the Taihu Lake Basin, Jiangsu Province, China

摘要

Non-point source pollution contributes greatly to lake eutrophication. This article explores a) the pollution status of rural southern Jiangsu and the Taihu Lake Basin; b) non-point source pollution control; and c) vein river non-point pollution control. Our work concerns an earthworm ecology filter, a capillary infiltration ditch, rural solid waste treatment and reuse technology. The tower earthworm eco-filter and capillary infiltration ditch technology for effluent COD_(Cr), NH_3-N, TN and TP meet the Environmental Quality Standards for Surface Water (China), Category IV.
