面向毒性控制的工业废水水质安全评价与管理方法

Evaluation and Management Methods for Toxicity Control of Industrial Wastewater

工业废水中含有多种多样的有毒有害污染物,仅用CODCr,BOD5等常规水质指标不能客观、准确地评价废水的水质安全性。提出了由常规水质指标、特征水质指标和综合生物毒性指标构成的工业废水水质评价指标体系;分析了生物毒性检测技术及其在工业废水评价中的应用,指出利用综合生物毒性进行废水水质安全性管理的必要性和重要性,并建议将水溞生物毒性测试作为我国工业废水毒性评价的首选方法芙崃斯谕夥纤锒?性控制标准的研究进展,指出需要根据我国水环境生物类别、工业废水污染物毒性特征和控制技术水平,研究、制定适合我国国情的工业废水毒性控制指标和毒性排放标准。

Evaluation and control of toxic pollutants in industrial wastewater is an import issue in the filed of water environmental pollution control. Only measuring quantitative integrated indexes such as CODCr,BOD5 is not sufficient for evaluating the safety of wastewater. Industrial wastewater water quality indexes including routine water quality indexes, bio-toxicity indexes and chemical characteristic indexes were proposed. Bio-toxicity tests and their application in industrial wastewater evaluation were discussed. The necessity and importance to carry out wastewater safety management using integrated bio-toxicity method was pointed out. It is suggested that the application of Daphnia toxicity tests for industrial wastewater safety evaluation should be the top choice in China. In addition, the progress of wastewater bio-toxicity control criteria at home and abroad was summarized, and it was pointed out that the bio-toxicity control index and toxicity discharge criteria for industrial wastewater which was suitable for China should be established according to water environmental creature type, toxic characteristic of industrial wastewater pollutants and control technology level.
