危险废物浸出毒性试验方法的研究

在分析各国危险废物浸出毒性试验方法的基础上,综合考虑我国气候状况(降雨量、酸雨现状)及工业固体废物处理处置现状,提出我国危险废物浸出毒性研究的技术路线为:通过模拟工业固体废物填埋场在不规范填埋处置且受酸雨影响条件下,有毒物质浸出向地下渗滤造成对地下水的污染,确定浸出毒性的浸取方法.浸出毒性保护目标为地下水,同时还介绍了主要技术参数液固比、浸取剂pH值和类型的确定方法.

The Study ofTestM ethodson Leaching Toxicity ofHazardousW aste

Hazardous waste leaching toxicity identification standard was one of the most important identification indexes for toxic solid waste,and widely used in heavy metal residue toxic determination.There was a leaching toxicity theoretical basis and methods in each country.But in China,leaching methods only use Japanese standard for reference.So the identification was short of persuasion and maneuverability.On the basis of study of leaching toxicity methods used in many countries,combined considering the natural weather trait(rainfall,acid rain pollution),waste characteristic and integrate factors involved in practice disposal site,the Chinese leaching toxicity procedure technical path was studied.
