摘要
以常州市典型的城北污水处理厂尾水、受纳水体藻江河、新区公园(湿地)以及藻江河沿岸的地下水为研究对象,对水体54种挥发性有机物,9种半挥发性有机物,11种重金属元素,生物性指标等进行了监测,并根据监测数据,采用层次分析法构建尾水排放水环境安全评价指标体系。通过开展尾水排放对水环境安全评价的研究,对提高水体的环境自净能力及改善城市河流水环境质量具有重要的理论与实际意义。
In this paper, the tail water of a typical sewage treatment plant in Changzhou, the receiving water of the Zaojiang River, the new park(wetland) and the groundwater along the Zaojiang River are studied. 54 kinds of volatile organic compounds, 9 kinds of semi-volatile organic compounds,11 kinds of heavy metal elements, biological indicators were monitored. Based on the monitoring data, the evaluation index system of environmental safety of tail water discharge was established by AHP. It is of great theoretical and practical significance to improve the self-purification ability of water body and the water environment quality of urban rivers by carrying out the study on the safety assessment of tail water discharge.
