摘要 污泥经过水泥固化后可转化为再利用的岩土工程建筑材料,对固化污泥的浸出毒性进行了研究,就pH值、Eh值、微生物活动对重金属浸出率的影响进行了探讨。研究结果表明,污泥中的重金属在水泥固化之后,其浸出毒性降低。 The sludge solidified by cement can be reused as building materials for geotechnical engineering.This paper analyzes the leaching hazardness of heavy metals from the solidified sludge as affected by pH,Eh and microorganism activities.Research results showed that the leaching toxicity of its has been decreased.
