摘要
污水厂污泥焚烧是一种有效的减量化处理方式,焚烧产生的污泥焚烧灰渣通常被运到填埋场进行填埋处置。根据污泥灰渣的物理特性,对其进行了急性毒性分析和水化活性分析,并经过无害化处理的污泥焚烧灰渣寻找到了使其资源化利用的新方法,即固化后制成的路基材料。用该法制成的路基材料抗压强度满足规定的技术要求,同时,重金属浸出毒性也满足国家固体废物排放标准的要求。
Incineration of sewage sludge is an effective reduction treatment,sewage sludge incineration ash is usually transported for landfill disposal.According to the physical characteristics of the sewage sludge incineration ash,acute toxicity analysis and hydration activity analysis are carried out,and new methods of sewage sludge incineration ash are found out for resource utilization with harmless treatment,which is making roadbed material after solidification.The compressive strength of this roadbed material can meet the technical requirements,while heavy metals leaching toxicity of solid wastes can meet the requirements of national emission standards for solid wastes.
