摘要
为探究多元生态修复技术对复合污染人工湖水质净化和保持的实际应用效果,采用“初期生态植草沟截留+中段生态雨水井过滤+末端水生植物修复”组合技术对武汉市玫瑰体育公园人工湖进行生态修复治理。修复结果表明,人工湖水质有了显著提升。NH_(3)N,TN,TP,COD_(Mn)的去除率分别为76.60%,52.11%,60.00%,71.04%,Chla浓度下降了51.10%,整体水质稳定在III类水质标准,水生态系统得到较好恢复。药剂投加费用比以往减少了16.18万元,碳减排收入为67.29万元。工程实施1年情况良好,稳定有效,为同类型湖泊治理提供了宝贵的理论和实践基础。
In order to explore the practical application effect of multiple ecological restoration technologies on the water purification and maintenance of the multi-polluted human lake,the combined technology of"initial ecological grass ditch interception+middle ecological rainwater well filtration+terminal aquatic plant restoration"was adopted to carry out ecological restoration and treatment of the Human lake in Wuhan Rose Sports Park.The results show that the water quality of the artificial lake has improved significantly.The removal rates of NH_(3)-N,TN,TP and COD_(Mn) were 76.60%,52.11%,60.00%and 71.04%,respectively,and the chlorophyll concentration decreased by 51.10%.The overall water quality was stable in the Class III water quality standard,and the water ecosystem was well restored.The cost of drug injection was reduced by 161,800 yuan,and the carbon emission reduction income was 672,900 yuan.The implementation of the project is good,stable and effective,which provides a valuable theoretical and practical basis for the treatment of similar lakes.
