Sewage sludge separation and purification device

Abstract

The invention provides a sewage sludge separation and purification device. One end of a sludge separation device is connected with a sludge mixing device, the other end of the sludge separation device is connected with a sewage treatment device, the sludge separation device comprises a sewage storage tank, a sludge centrifugal device and a sludge recovery device, the sludge centrifugal device is arranged at the bottom end in the sewage storage tank, the sludge recovery device is arranged at the top end of the sewage storage tank, and a sewage discharge pipeline is arranged at the bottom end of the sewage storage tank. Sewage is biodegraded by biotechnology, so that various environmental pollutions caused by throwing various chemical drugs into the sewage are reduced, some sludge exists in the sewage and has a certain influence on the biodegradation process of the sewage, the sewage and the sludge are firstly and effectively separated, and the separated sludge is applied to other fields after treatment.

Description

technical field [0001] The invention relates to the technical field of environmental protection, and more specifically relates to a sewage sludge separation and purification device. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] In recent years, the discharge of urban domestic sewage has become the main pollution source of China's urban water. Urban domestic sewage treatment is the top priority of urban water conservation and urban water environment protection at present and in the future. This requires us to deal with domestic sewage facilities. Construction is an important pa...

AI Technical Summary

Problems solved by technology

[0004] The present invention overcomes the deficiencies in the prior art. The current sewage treatment pool has high production cost and poor treatment effect, and provides a sewage sludge separation and purification device, which uses biological technology to carry out biodegradation treatment of sewage, thereby reducing the amount of sewage Various types of pollution to the environment caused by putting various chemicals in the environment, there will be some sludge in the sewage, and the sludge will have a certain impact on the biodegradation process of the sewage. First, the sewage sludge is effectively separated, And the separated sludge can be used in other fields after treatment
