摘要
本文介绍了在实验室模拟条件下,利用蚕豆根尖的微核效应,分析了3种染料溶液及实际污水的生物毒性和它的去除方法。实验表明,这3种染料和实际污水都存在着生物毒性。在溶液 pH,温度,臭氧发生量一定条件下,3种染料溶液经臭氧氧化后,生物毒性去除率达56%以上,实际污水经臭氧处理后,生物毒性去除达31.09%。
Abstract Under laboratory simulated conditions,the biological toxicity and its
removal method of dye solutions and of sewage were studied.Experimental results
showed that the biological toxicity of the dye solutions and of sewage existed.
When pH,tempe rature,and quantity of ozone generated were constant,the biolo-
gical toxicity reduction extent of the dye solution by was Ozone over 56%,and that
of sewage was 31.09%.
