造纸助剂的生物毒性评价

The Assessment on the Biological Toxicity of Papermaking Additives

本论文中对几种造纸助剂的毒性进行了研究,采用了静水式及半静水式的急性毒性试验方法,试验结果表明:聚酰胺-环氧氯丙烷树脂、三聚氰胺甲醛树脂、荧光增白剂(VBL)、XQ-DF脱墨剂的24h的半致死浓度分别为:94.95mg/L、1890.2mg/L、500.4mg/L、16.3mg/L;聚丙烯酰胺的96h的半致死浓度为258.2mg/L。该试验结果为制浆造纸过程助剂的添加以及废水的后处理提供了参考,同时也为制浆造纸工业环境影响评价提供部分基础数据。

In this paper,the toxicity of several papermaking additives was inv es tigated.In this acute toxic test,the static water and the semi-static water tes t were adopted.The conclusion of the test is loading:the 24h-LC50 of the PAE,me lamine resin,fluorescent bleaches VBL and XQ-DF deinking reagent is 94.95mg/L,1 890.2mg/L,500.4mg/L,16.3mg/L;the 96h-LC50 of the polyacrylic amide is 258.2mg/L .The test can accommodate reference to the treatment of wastewater and additive using.At the same time,it is a part basic research of the Environmental Impact Assesment.
