摘要:

中水回用系统在预处理阶段需脱除悬浮物、硬度等杂质,以确保膜系统的稳定运行,从而产生大量的污泥。预处理装置产生的污泥(含水质量分数在99%左右)不仅非常细散,而且黏性差,不易压滤。通过摸索和研究,最终采用叠螺压滤机+带式压滤机组合的方式实现连续压泥,既减轻了操作和维修的工作量,又满足了污泥处理的要求,得到的泥饼含水质量分数在70%左右。

Abstract:

In the pretreatment stage, the reclaimed water reuse system needs to remove impurities such as suspended solids, hardness, etc. to ensure stable operation of the membrane system, and thus a large amount of sludge is generated. The sludge produced by the pretreatment unit (the water mass fraction is about 99%) is not only very finely dispersed but also poor in viscosity, so it is not easy to filter press. Through repeated exploration and research, a continuous sludge press is finally achieved using a combination of stacked screw filter press and belt filter press, it not only reduces the workload of operation and maintenance, but also satisfies the sludge treatment requirements, the water content of obtained filter cake is about 70%.
