工业园污水处理厂污泥危险特性鉴别研究

Study on Hazardous Characteristics Identification of Sludge from Wastewater Treatment Plant of Automobile Industrial Park

摘要: 以某工业园区污水处理厂为例，通过重点排水企业原辅材料、产品方案、工艺流程和园区废水处理工艺的分析，结合GC-MS、ICP-MS扫描对废水处理污泥危险特性初筛，确定污泥危险特性检测因子；经检测后判定该污水处理厂污泥不具有危险特性，为同类型废水处理污泥鉴别提供思路，对此类污泥危险特性鉴别重点关注要素提出建议。

Abstract: This paper takes a sewage treatment plant in an industrial park as an example, by analyzing the raw and auxiliary materials, product schemes, technological processes and wastewater treatment processes of key drainage enterprises in the leading industries of the park, combined with GC-MS and ICP-MS scanning on the preliminary screening of the hazardous characteristics of sludge in wastewater treatment in the zone, and to determine the risk characteristics of sludge detection factor. After testing, the sludge of the sewage treatment plant was determined to have no hazardous characteristics, providing a way for the identification of sewage sludge in the same type of wastewater treatment plant, and suggestions were made for the key factors to identify the haz-ardous characteristics of this kind of sludge.
