用发光菌急性毒性试验评价工业废水毒性初探

A Primary Research on Industrial Waste Water Toxicity Assessment by Using Photobacteria

本文利用发光菌急性毒性试验对齐齐哈尔市部分工厂废水进行测试.并对结果进行毒性级别划分,10月份排放废水毒性较低,3月份排放废水毒性较高,同时又与理论数据作以比较,证明此方法能很好地反映水质综合毒性.

This paper is about toxicity assessment of industrial waste water of Qiqihar city with photobacteria acute toxicity test. It is found that the relative luminosity factor of photobacteria can stand for the water toxicity. The toxicity of water in October is more severe than that in March. And also compared with the theoretical chemical and physical data,the result of photobacteria luminosity factor combined effect of water toxecity is proved to be satisfactory.
