重金属市政污泥固化稳定化技术研究

摘要

A sewage treatment plant sludge generated for solidification and its unconfined compressive strength test,water stability,leaching-out toxicity,permeability,etc. index were determined. The result showed that the unconfined compressive strength test of the treated sludge reached 0. 2 MPa,the water stability changed a little,the leaching-out toxicity reached identification standards and the permeability reached the landfill standard.%对某污水处理站产生的污泥进行固化稳定化处理，测定其无侧限抗压强度、水稳定性、重金属浸出毒性、渗透性等指标。实验表明，处理后污泥无侧限抗压强度可达0.2 MPa，水稳定性无明显变化，重金属浸出浓度低于毒性鉴别标准值，渗透性满足填埋指标要求。
