摘要
城中湖泊地处人口密集、产业发达区域,受人为因素影响,城中湖泊污染日益严重。为改善城中湖泊的生态环境,对城中湖泊开展水环境综合整治是必要和迫切的。以武汉市莲花湖的水环境综合治理为例,在污染源调查分析的基础上,通过水质、底泥分析与评价得出:莲花湖水体为劣Ⅴ类,整体处于“中-重度富营养化”状态,其中2#、3#、4#湖区的水体污染最为严重;底泥中重金属的危害程度为“轻微”,但总氮、总磷污染严重,达到“重度污染”等级。针对莲花湖的污染特征,提出了“源头治理—生态恢复—活水保质—水景观改善”的治理思路,制定了切实可行的治理措施,为城中受污染湖泊水环境综合治理提供了参考。
Lakes in cities are located in densely populated and industrially developed areas.Affected by human factors,lake pollution in cities is becoming increasingly serious.In order to improve the ecological environment of urban lakes,it is necessary and urgent to carry out comprehensive water environment improvement for urban lakes.Taking the comprehensive management of water environment in Lianhua Lake in Wuhan as an example,based on the investigation and analysis of pollution sources,the water quality and sediment quality analysis and evaluation show that the water body of Lianhua Lake is inferior V,and the whole is in″medium-heavy eutrophication″.Among them,the water pollution of 2#,3#and 4#lake areas is the most serious.The degree of hazard of heavy metals in the sediment is″mild″,but the pollution of total nitrogen and total phosphorus is serious,which reaches the grade of″severe pollution″.According to the pollution characteristics of Lianhua Lake,this paper puts forward the treatment idea of″source control,ecological restoration,living water quality preservation and water landscape improvement″,and formulates feasible control measures,which provides a reference for the comprehensive treatment of polluted lake water environment in cities.
