Description
技术领域technical field
本实用新型涉及一种应用于污水处理的泥水分离装置，应用于污水处理领域，特别是应用于污水处理厌氧工艺出水的泥水分离。The utility model relates to a mud-water separation device applied to sewage treatment, which is applied to the field of sewage treatment, in particular to the mud-water separation of the effluent of anaerobic process of sewage treatment.
背景技术Background technique
在污水处理过程中泥水分离尤为关键，直接影响污水处理的效果，如在UASB工艺中出水进入下一个处理工序，往往出水带出有颗粒污泥，使UASB池中的污泥浓度越来越低，颗粒污泥减少，现有生化处理工艺中都没有泥水分离装置，有些工艺如接触氧化工艺，采用污泥回流泵来实现部分污泥的回流，但一般污泥的含水率都很高，回流大部分是水，如果回流沉淀池污泥，又因为加了混凝和絮凝药剂，回流这种污泥会影响生化的效果。常用泥水分离装置需要动力装置，比较耗电。所以急待研究一种将污水生化池出水的大部分污泥回流的装置，又节能的泥水分离装置。The separation of mud and water is particularly critical in the process of sewage treatment, which directly affects the effect of sewage treatment. For example, when the effluent enters the next treatment process in the UASB process, granular sludge is often brought out of the effluent, which makes the sludge concentration in the UASB pool lower and lower. , the granular sludge is reduced, and there is no mud-water separation device in the existing biochemical treatment process. Some processes, such as the contact oxidation process, use the sludge return pump to realize the return of part of the sludge. However, the moisture content of the general sludge is very high, and the return flow Most of it is water. If the sludge in the sedimentation tank is returned, because of the addition of coagulation and flocculation agents, the return of this sludge will affect the biochemical effect. Commonly used mud-water separation devices require a power device, which consumes more power. Therefore, it is urgent to study a device for returning most of the sludge in the sewage biochemical tank effluent, and an energy-saving mud-water separation device.
