摘要
当前我国城市污水污泥数量不断增加,污泥减量化是一项重要的环境措施,污泥焚烧是一种符合我国国情的污泥处置方式。为了提高经济效益,在对污泥焚烧前,需要对城市污泥进行深度脱水。文章对污泥脱水机理、脱水过程的影响因素进行分析,结合多年工作经验,对污泥脱水研究进展、城市污水处理厂污泥处理处置路线进行总结。
The quantity of municipal sewage sludge is increasing in our country,sludge reduction is an important environmental measure,and sludge incineration is a sludge disposal method in line with China's national conditions.In order to improve economic benefits,it is necessary to carry out deep dewatering of municipal sludge before incineration.In this paper,the mechanism of sludge dewatering and the influencing factors of dewatering process are analyzed,and the research progress of sludge dewatering and the disposal route of municipal Sewage Treatment sludge are summarized.
