再生水补给湖泊表观污染治理效果研究
Visible water pollution treatment in a lake replenished with reclaimed water
摘要
Abstract
Urban lakes replenished by reclaimed water have a reduced landscape function due to the high nutrient content of the water body and susceptibility to surface pollution.In this paper,a reclaimed water replenished lake in the Yangtze River protection area was taken as a case study,with closed-and open-water body areas for the control experiments.Transparency(SD),chlorophyll a(Chl-a),and turbidity(NTU)under different imported material ratios and dosages were analyzed.Then,an economically effective management plan was proposed.The results show that visible pollution of the lake is serious.The imported material with 10％AC and 90％VZ has the best perfor-mance,for which,SD has been improved by more than 12％,NTU is decreased by 28.14％,and Chl-a content is reduced by 30.84％.Low doses(10～25 g/m3)of the composite material can rapidly enhance the visible appearance of the lake,whereas,high doses(50g/m3)may induce short-term fluctuations of NTU.However,it demonstrates a sig-nificant long-term effect on Chl-a removal,achieving more than 40％reduction compared to the control case.It is rec-ommended to utilize a material combination of 10％AC+90％VZ,with cost of 0.2～0.4 RMB/m3,which is signifi-cantly lower than the costs associated with sediment removal and other methods.The research provides valuable insights for managing visible water pollution in lakes and similar water bodies replenished with reclaimed water.关键词
