Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to flocculation and clarification sewage treatment equipment used for sewage treatment. Background Art

[0002] Sewage treatment has always been one of the important aspects of environmental protection. After being treated, sewage can not only reduce or avoid pollution to water resources and the environment, but also make water secondary utilization. Sewage will go through multiple steps during treatment, and flocculation and clarification is one of the steps. Flocculation and clarification sewage treatment equipment will be used in such treatment. However, the existing flocculation and clarification sewage treatment equipment still has some shortcomings. For example, the existing flocculation and clarification sewage treatment equipment does not have the cleaning function. After long-term use, the filter screen used to filter flocculation will accumulate a large amount of flocculation, which will cause the sewage to be unable to flow normally, thereby affecting the flocculation and clarification effect. Moreover, most of the existing flocculation and clarification sewage treatment equipment are large in size, which leads to poor maneuverability and inability to adjust the position according to the needs of use. For this reason, we propose flocculation and clarification sewage treatment equipment for sewage treatment. Utility Model Content
