化工废水毒性评价方法及毒性削减研究进展

Research progress of toxicity evaluation methods and toxicity reduction of chemical wastewater

化工废水排放量大,成分复杂,包含多种有毒有害物质,如果不经过适当的处理将会对自然环境乃至人们的身体健康造成一定的危害。生物毒性测试可以在化学分析的基础上更加全面系统地评价水质的安全性,文章综述了不同化工行业废水的毒性削减情况,为化工废水的毒性减排提供借鉴。

Chemical wastewater has the features of large emissions, complex composition, and it contains a variety of toxic and harmful substances. It will cause certain harm to the natural environment and even people’s health without the effective treatment. Biological toxicity testing can evaluate the safety of water quality more comprehensively and systematically base on the chemical analysis. This article summarized the toxicity reduction of wastewater in different chemical industries, and provided a reference for the reduction of toxicity of the chemical wastewater.
