水性建筑涂料废水处理污泥危险特性分析
Analysis of Hazardous Characteristics of Sewage Sludge from Building Waterborne Coating
-
摘要: 文章从水性建筑涂料使用原辅料分析着手,结合8家水性建筑涂料废水处理污泥的实际检测结果,得出水性建筑涂料废水处理污泥不具有危险废物鉴别标准规定的危险特性的结论。该结论有助于同行业该类废水处理污泥或环境污染案件涉及同类污泥的危险特性判断与认定,为该类废物管理提供依据。同时建议在制定该类废水处理污泥鉴别方案时宜优先考虑毒害性强、检出值大、累积毒性贡献多、检出率高的污染物作为检测指标。Abstract: Based on the analysis of raw and auxiliary materials of the building waterborne coating and the actual test results from 8 building waterborne coating sludges, the conclusion is drawn that the building waterborne coating sludge does not have the hazardous characteristics specified in the hazardous waste identification standard. This conclusion will be helpful to judge and identify the dangerous characteristics for similar sewage sludge or environmental pollution cases with this kind of sewage sludge in the same industry, and provide management support for the kind of waste. It is suggested that the pollutants with strong toxicity, high detection value, cumulative toxicity contribution and high detection rate should be considered as the detection index for the sludge identification scheme.
