人工湖水环境分析及其污染控制措施(英文)

目的]寻找解决景观水体富营养化的有效措施。方法]在综述城市景观水体特点和防治现状的基础上,以西安市某高校校区人工湖为例,对比分析了修远湖和明远湖景观水体污染现状,并提出控制水体水质富营养化污染的治理及修复措施。结果]修远湖与明远湖景观水体水质TN、TP、Chl-a、NH3-N、CODMn等指标均严重超标,水体呈现重度富营养化状态。大气降水及其产生的径流所携带的N、P营养盐,以及人类活动产生的生活垃圾是人工湖的主要外源污染源,人工湖的底泥污染物释放是导致水体水质变差的内源污染源。结论]该研究提出了控制人工湖水体污染的措施,为人工湖的建设、运行管理以及人工湖水环境维护提供了科学依据。

Analysis on Aquatic Environment of an Artificial Lake and Control Measures to Its Pollution

Objective] This study aimed to find out effective measures to solve landscape water eutrophication. Method] Based on an overview of the urban landscape water characteristics and pollution control situation, taking an example of the artificial lakes in a campus in Xi’an, we comparatively analyzed the present pollution situation of Xiuyuan Lake and Mingyuan Lake, and provided controlling measures against eutrophication pollution, as well as restoration measures. Result] All the indicators (TN, TP, Chl-a, NH3-N, CODMn) of the landscape water quality in both Xiuyuan Lake and Mingyuan Lake went severely beyond the Grade Ⅳ standards, presenting a state of heavy eutrophication. Nitrogen, phosphorus and other nutrient salts carried by atmospheric precipitation and its runoff, as well as domestic garbage generated by human activities were primary exogenous pollutants of the artificial lakes. And the release of sediment pollutants was endogenous substances causing deterioration of water quality. Conclusion] This paper presents some measures to control the pollution of artificial lakes, and provides scientific references for the construction, operation and management of artificial lakes, as well as maintenance of aquatic environment.
