A sewage impurity pretreatment device based on rotational centripetal force

Abstract

The invention provides a sewage impurity pretreatment device based on rotational centripetal force, and relates to the technical field of sewage treatment. The sewage impurity pretreatment device based on rotational centripetal force includes a tank body, a surrounding pipe is fixedly installed on the periphery of the bottom of the tank body, a water inlet is fixedly connected to the left end of the surrounding pipe, and an outlet is fixedly connected to the inner side of the surrounding pipe. A water outlet, the bottom end of the tank body is fixedly installed with a sewage outlet, and the inside of the tank body is fixedly installed with a sewage collection pipe. The sewage impurity pretreatment device based on the rotating centripetal force can first make the colloids, organic matter and impurities in the sewage adhere to each other to form larger flocs, and concentrate them into the sewage collection pipe for collection and discharge, avoiding the filter mesh It is more time-saving and labor-saving, and can be used repeatedly, which improves the cleaning efficiency, uses the momentum of the water flow to make the sewage rotate, avoids the use of traditional paddles, and is more energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage impurity pretreatment device based on rotational centripetal force. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, Catering and other fields, but with the development of society, more and more sewage is produced. In the process of sewage treatment, the first step is to remove some fixed impurities in sewage. [0003] However, the existing sewage treatment devices use filtration to pre-treat the sewage, and use the filter screen to block and clean the impurities in the sewage. However, the filter screen needs to be cleaned and replaced frequently, which is time-consuming and...

Problems solved by technology

[0003] However, the existing sewage treatment devices use filtration to pretreat the sewage, and use the filter to block and clean the impurities in the sewage. However, the filter needs to be cleaned and replaced frequently, which is time-consuming and laborious. If If the filter is blocked or there are impurities remaining, it will affect the filtering effect and progress, and it can only remove the particles larger than the mesh, and cannot effectively clean the small particles and impurities.
