Sewage treatment apparatus for intensively replacing filtering device, and replacement method thereof

Abstract

The invention discloses a sewage treatment apparatus for intensively replacing a filtering device, and a replacement method thereof. The apparatus comprises a box body, a filter frame is arranged at the top of the inner cavity of the box body, the top of the filter frame extends to the outside of the box body, the tops of two sides of the filter frame are fixedly connected with support blocks, thebottoms of the support blocks are in contact with the top of the box body, the top of the left side of the box body is fixedly connected with an electric telescopic rod, the bottom of the electric telescopic rod is fixedly connected with a horizontal plate, the right end of the horizontal plate is fixedly connected with a first motor, and the bottom of the rotating shaft of the first motor is fixedly connected with a buffer mechanism. The apparatus has the advantages of intensive dismounting replacement of a filter plate, and good filtering effect, and solves the problem of the influences ofobstruction of the filter plate, easily caused by accumulation of impurities on the filter plate in the long-time filtering process due to inconvenient intensive replacement of most filter plates fixedly mounted in existing sewage treatment apparatuses, on sewage purification.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device and a replacement method for centralized replacement of a filter device. 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, etc. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, while domestic sewage It refers to the complex mixture of various forms of inorganic and organic matter, including: floating and suspended solid particles of large and small sizes; colloida...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sewage treatment device and a replacement method that can centrally replace the filter device, which has the advantages that the filter plate can be disassembled and replaced in a centralized manner, and the filtering effect is good. Fixed installation, it is inconvenient to centrally replace it. During the long-term filtration process, impurities will accumulate on the surface of the filter plate, which will easily cause blockage of the filter plate, thus affecting the problem of sewage filtration.
