Sludge stirring device for environmental governance

Abstract

The invention relates to the technical field of sludge flocculation, and discloses a sludge stirring device for environmental governance, the sludge stirring device comprises a stirring pool, a lifting assembly is mounted on the inner wall of the stirring pool, the lifting assembly is used for driving a mounting assembly to lift along the central axis direction of the stirring pool, and a stirring assembly, a spraying assembly and a water pumping assembly are mounted on the mounting assembly. The lifting assembly drives the mounting assembly to lift at a fixed distance, so that the stirring assembly, the spraying assembly and the water pumping assembly perform layered precipitation on particulate matters in sewage in the stirring pool, and the sewage in which the particulate matters are flocculated and precipitated is discharged, so that layered precipitation is realized; and the problem that the flocculating constituent still floats in the whole container under the action of integral rotational flow and cannot realize fixed-area regionalized precipitation is avoided.

Description

technical field [0001] The invention relates to the technical field of sludge flocculation, in particular to a sludge stirring device for environmental treatment. 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. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Flocculation and sedimentation tank is currently the most economical and efficient process for treating suspended solids at home and abroad. Sludge is formed by sedimentation of particulate matter in sewage by adding flocculants....

AI Technical Summary

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a sludge stirring device for environmental treatment, which has the advantages of layer-by-layer sedimentation, accelerated flocculation and sedimentation, etc., and solves the problem that the flocs are still in the entire container under the action of the overall swirl. Floating, unable to achieve fixed-area sedimentation and slow settling speed and low efficiency of flocs after flocculation of sewage and chemicals

[0011] In order to solve the technical problems that the flocs are still floating in the entire container under the action of the overall swirling flow, the sedimentation in a fixed area cannot be realized, and the settling speed of the flocs after the flocculation of sewage and chemicals is relatively slow and the efficiency is low, the present invention provides the following Technical solutions:
