临沂市人工湿地净化效能评价
|
摘要
以临沂市人工湿地为研究对象,采用层次分析法对人工湿地净化效能进行了综合评价。结果表明:临沂市人工湿地的运行维护水平较低,大部分湿地处于"亚健康"的状态。21处主要人工湿地综合评价为"良好"的仅1处,"较好"的有7处,"合格"的有5处,"较差"的有4处,"差"的有4处。存在的主要问题包括进水水质水量控制较差、植物管理缺乏科学性、老化湿地亟需复壮、管理机制亟待理顺、经费缺口较大等。根据微污染河水净化人工湿地、污水厂尾水净化人工湿地、农村污染治理人工湿地等类型,提出了人工湿地管理和修复建议。
The purification efficiency of constructed wetlands in Linyi was studied using the analytical hierarchy process to make a comprehensive assessment. The results were as follows: the operation and maintenance level of the constructed wetlands in Linyi was low, and most wetlands were at a "sub-health" state. The 21 constructed wetlands were evaluated,only one of them was "good", and 7, 5, 4, 4 of them were respectively "better", "qualified", "poor" and "worse". The main problems include poor water quality control of influent water, lack of scientific management of plants, rejuvenation of aging wetlands, management mechanism to be rationalized, and large funding gap. Considering various types of artificial wetlands for pollution control, such as slightly-polluted river water purification, sewage treatment plant water purification, and rural pollution control, measures for management and restoration of artificial wetland were proposed.
