| 摘 要： | 借鉴美国环保署制定的毒性物质鉴别评价技术(TIE),直接从企业生产的工艺出发,结合废水的主要水质指标对某石化厂乙烯工业废水进行毒性鉴别试验,发现废水中的苯和硫化物对大型蚤具有明显的致死性,其中苯是废水中的关键毒物。所取废水对测试生物大型蚤的24 h-LC50均值为53.68%,其中主要致毒物质苯的含量大约30 mg/L。

| Abstract: | This article draws toxicity identification evaluation technology developed by the USEPA(TIE),starting directly from the process of the production,in accordance with main quality indicators of wastewater for ethylene industrial wastewater of a petrochemical plant for toxicity identification testing,it has been found that benzene and sulfur compounds in wastewater to daphnia magna have significantly toxicity.Among them,benzene is the key toxicant.The 24 h-LC50 mean of wastewater to daphnia magna is 53.68%,the content of benzene is about 30 mg/L. |
