一种复合式污泥脱水的工艺方法
摘要：
本发明的目的是针对通过现有的污泥脱水工艺无法进一步降低污泥含水率的情况，提出了一种污泥脱水的工艺方法，该脱水工艺方法结合了PAC对污泥的絮凝作用、极性水溶性小分子醇类化合物对蛋白质的改性作用，并结合水热处理对细胞膜的破坏作用，开发出一种污泥脱水处理新工艺。本发明具有采用PAC、甲醇和水热联合脱水，试剂添加量少，工艺流程简单，进行脱水后，能使污泥含水率降至65％以下等优点。
摘要（英）：

The invention provides a sludge dewatering process for the situation that an existing sludge dewatering process cannot further reduce the moisture content of sludge. The dewatering process develops anovel sludge dewatering treatment process by combining a flocculation effect of PAC on the sludge with a modification function of polar water-soluble micromolecule alcohol compounds and a destructiveeffect of hydro-thermal treatment on the cytomembrane. The sludge dewatering process has the advantages that the PAC, methyl alcohol and the hydro-thermal treatment are adopted to be combined for dewatering, the additive amount of reagents is small, the process is simple, and the moisture content of the sludge can be reduced to 65% or below after dewatering.
