摘　　要：以石家庄市3个城市污水处理厂的进出水为研究对象,采用发光菌青海弧菌Q67检测急性毒性,利用蚕豆根尖微核试验检测遗传毒性,结果表明：3个污水处理厂进水对发光菌的抑制率为32.80%-62.80%,对蚕豆根尖细胞产生的微核诱导率为4.09‰-7.60‰;3个污水处理厂出水在理化指标符合国家排放标准的基础上,产生的抑光率为8.20%-18.40%,出现的微核率为1.19‰-3.75‰。毒性评价结果表明,与进水相比,污水处理厂出水的生物毒性虽有大幅降低,但仍对水环境中的生物有不同程度的毒性效应。In order to explor the inlet and outlet water of the sewage treatment plant in Shijiazhuang city, the acute toxicity of water samples was detected by Qinghai Vibrio Q67, and the genetic toxicity was detected by Vicia faba micronucleus test. The results show that the influents of three sewage treatment plants on luminescent bacteria inhibition rate is 32.80%-62.80% and micronucleus rate of Vicia faba root tip cells is 4.09‰ -7.60‰. Based on the national dyeing wastewater discharge standards, the light inhibition rate and the micronucleus rate of the effluents is 8.20%-18.40% and 1.19‰-3.75‰ respectively. The toxicity evaluation results show that the biological toxicity of wastewater is significantly lower than influents, but it still has different toxic effects on the aquatic environment.
