Study On Restoration Of Water Body In Urban River Network Of Sunan Area

The pollution of river system in Sunan area was investigated and the analysis of pollution source of river system was conducted. Based on the analysis results, the water restoration plan and measures were established. The water restoration plan was optimized through analyzing the site restoration case. In addition, the project techno-economic effect was also analyzed.After enclosure of municipal sewage discharge, the oxidation reagents were dosed into water for sediments pollution control. By surface aeration and dosage of KOT bacteria reagents, the odor and darkness of the water body were eliminated and the water transparence was improved. The landscape function of the river was recovered after restoration. The dynamic restoration was also conducted to reduce the pollution in river. The effluent of municipal sewage plant was further purified as the clean water resource of river and enhanced the flow of river water in order to achieve long term restoration effect to improve water quality of Zhongxin River.
