摘要
通过分析影响污泥机械脱水的因素,指出污泥机械脱水的难点是部分结合水的去除,在此基础上,概述了国内外污泥机械脱水前处理方法的研究现状,最后提出污泥机械脱水前处理较好的方法为物理法和生物法,以期为污泥机械脱水前处理方法的选择提供理论支持。
The paper put forward the difficulties in removing some bound water of sludge mechanical dewatering by analyzing the influence factor？of it.Based on this,the paper summarized the current situation of pretreatment methods before sludge mechanical dewatering at home and abroad.Finally,it advanced that the physical and biological methods is the better pretreatment method before sludge mechanical dewatering,so as to supply the theory support for the selection of pretreatment method before sludge mechanical dewatering.
