【摘要】 随着中国城市化的快速推进,产生了一系列的环境问题,而解决因城市发展而带来的自然水体(如城市湖泊)污染及其治理问题是一项耗资巨大而又十分复杂的系统工程。就中国的经济实力而言,污水处理的技术经济指标往往是选择方案时必须首先考虑的问题。传统的活性污泥法基建投资大,运行费用高,且处理后的出水排入水体后仍将引起"富营养化"等环境问题。而人工湿地具有投资省,处理效果较好的优势,因而是一种非常值得探索和尝试的全新的处理方法。以该湖泊的人工湿地处理前后的水质效果进行对比分析,以期为今后相似的城市湖泊的生态治理提供一些借鉴。更多还原

【Abstract】 Along with the rapid development of urbanization in China,makeing a series of environmental problems,and solutions for pollution natural water as the urban development(e.g.,Urban lakes)is a costly and complex system engineering.For China’s economic strength,technical and economic indexes of sewage treatment options are often must the first problem which we should consider.For the traditional method of activated sludge,investment in infrastructure and operating expenses are very high,and the water treatment which into nature will causea a series of environmental problems(such as the "eutrophication").Artificial wetland has many advantages,investment is provincial,the treatment effect is good,so it is a new treatments which is very worthwhile to explore and try.Comparative analysis the results of water treatment with artificial wetland of the lake,so as to provide some references for ecological management of similar urban lakes on future.更多还原
