人工湿地处理低浓度生活污水的现状分析

摘要

This paper analyies the present conditions of the constructed wetland dealing with low concentration sewage and existing main problems and the insufficiency, think that the main restraining factors of the application of constructed wetland dealing with sewage are secondary pollution of plant nature wilted, big pollution load impact and the degeneration of treatment effect with running time. The constructed wetland environment control and sewage of anaerobic wastewater treatment technology combined with constructed wetland and the economic benefit is constructed wetland sewage treatment of low concentration of future development direction.%对人工湿地处理低浓度生活污水的现状及存在的主要的问题和不足进行了分析,认为湿地植物自然枯萎造成的二次污染、大污染负荷冲击及处理效果随运行时间的退化是制约人工湿地在生活污水处理上应用的主要因素;人工湿地运行环境的人工调控、生活污水的厌氧处理与人工湿地处理工艺结合及经济效益体现是人工湿地处理低浓度生活污水的未来发展方向.
