原污泥

与原污泥相比，污泥液化残渣中重金属的环境风险明显降低。

Compared with raw sewage sludge , the environmental risk of heavy metals in the liquefaction residues declined significantly .

本研究考察了原污泥和经碱处理的污泥在不同初始pH（3.0～12.5）条件下的产氢效果，以及污泥性质和污泥浓度等对产氢效果的影响。

Batch tests of fermentative hydrogen production under different initial pH ( 3.0 ~ 12.5 ) were compared using the raw sludge and alkaline pretreated sludge .

原污泥可以用来焚烧，可以有效地减少含水率。

Raw sludge can be incinerated , provided the water content is sufficiently reduced .

原污泥和消化污泥也可以用卫生填埋来处置。

Raw or digestion sludge can be also be disposed of in sanitary landfills .

该装置将原污泥处理系统中的污泥分离池、浓缩罐和机械脱水设备合为一体，可对站内污水池底部的各种污泥进行处理。

This equipment integrates the oily sludge separating pool , concentrating tank and mechanical dehydrating units in a system and can treat different kind of oily sludge at the bottom of sewage pool .
