Description

[0002] In the field of sewage treatment, with the rapid development of industrialization and urbanization, the composition of sewage is becoming increasingly complex and the difficulty of treatment is increasing. Although traditional sewage treatment methods, such as physical sedimentation and biodegradation, can remove harmful substances in sewage to a certain extent, they are often unable to cope with high-concentration and difficult-to-degrade pollutants.

[0003] The existing high-efficiency sedimentation-type sewage treatment device includes a main body, a sludge hopper, an inlet pipe, a water collection tank, an outlet pipe, a sludge discharge pipe and a number of support columns. A sludge scraping mechanism is arranged in the main body, and a delivery mechanism is arranged above the main body. The sludge scraping mechanism includes a first motor, a rotating rod, a cylinder, a moving ring and two cleaning components. The delivery mechanism includes a driving component, a push rod, a push plate, a material storage box and a feeding pipe. The high-efficiency vertical flow sedimentation tank for sewage treatment cleans the solid sediment remaining at the bottom of the sedimentation tank through the sludge scraping mechanism. In addition, flocculant is delivered into the sedimentation tank through the delivery mechanism to improve the sedimentation efficiency.

[0004] The delivery mechanism in the existing device adopts a fixed delivery point for the delivery of the agent, and lacks the ability to dynamically adjust according to the actual conditions of the sewage, which makes it difficult to achieve uniform mixing of the agent and the sewage.
