我国再生水水质生物毒性监测研究进展

Research Progress on Monitoring of Biological Toxicity of Recycled Water in China

再生水投入应用前,必须对其生态风险进行评估,而生物毒性是其中一项主要评估指标。污水处理厂经由一系列处理后,促使再生水生物毒性有所降低,但经过氯酸钠与臭氧等消毒剂处理后会产生毒性副产物,增加水生物的毒性作用。论文从发光细菌、细胞毒性等方面探究再生水水质生物毒性监测问题。

The ecological risk of reclaimed water must be assessed before it is put into use, and the biological toxicity is one of the main assessment indicators. After a series of treatment, the biological toxicity of reclaimed water can be reduced, but after treatment with disinfectants such as sodium chlorate and ozone, toxic by-products will be produced and the biological toxicity of reclaimed water will be increased. From the aspects of luminescent bacteria and cytotoxicity, this paper explores the problem of monitoring the biological toxicity of reclaimed water.
