Sewage precipitation device for environmental protection

Abstract

The invention provides a sewage precipitation device for environmental protection. The sewage precipitation device for environmental protection comprises a base, a portal frame is fixedly installed at the top of the base, a precipitation barrel is fixedly installed on the inner wall of one side of the portal frame, a frame located above the precipitation barrel is arranged in the portal frame, and a first rodless air cylinder is fixedly installed on the inner wall of the top of the portal frame; a rodless air cylinder I is arranged in the settling barrel, a connecting seat I is fixedly mounted on a movable block of the rodless air cylinder I, the bottom of the connecting seat I is fixedly connected with the frame, a scraping barrel is arranged in the settling barrel and is in contact with the inner wall of the settling barrel, and a scraping ring is fixedly mounted at the top of the scraping barrel and is in contact with the inner wall of the settling barrel. The sewage sedimentation device for environmental protection provided by the invention has the advantages that a person does not need to enter the tank to clean sediments and attachments, the cleaning is convenient, and the impurity filtering effect and the sewage treatment efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage sedimentation device for environmental protection. Background technique [0002] Sewage treatment is the process of purifying sewage so that it can meet the water quality requirements for discharge into a water body or for reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical, catering and other fields. In sewage treatment, the use of flocculants to settle sewage is one of the most important stages. This precipitation method can filter out most of the impurities in the sewage, providing a good foundation for subsequent further purification. [0003] However, the traditional precipitation treatment is generally to directly pour the flocculant into the sewage and wait. On the one hand, this treatment method makes all the sediment sink to the bottom, which is t...

Problems solved by technology

[0003] However, the traditional sedimentation treatment is generally to directly pour the flocculant into the sewage and wait. On the one hand, this treatment method makes all the sediment sink to the bottom. It is time-consuming and laborious to manually clean the fine filter later, and it needs to enter the pool Moreover, some attachments will directly adhere to the inner wall of the fine filter, and manual cleaning is also troublesome. On the other hand, the sedimentation effect that can be achieved by only one flocculation sedimentation is not ideal, and the filtration effect is relatively general. Moreover, a single sewage sedimentation can only carry out a batch of sewage sedimentation work, making the sewage treatment efficiency relatively low
