Sewage treatment filtration device

Abstract

The invention discloses a sewage treatment filtration device. The sewage treatment filtration device comprises an upper shell, a base plate, a lower shell, a water inlet pipe, a water pump, a driven gear, a conveyor belt, a sewage pipe and a sewage sedimentation tank, wherein the sewage sedimentation tank is arranged on the left side of the upper end of the base plate. Through the arrangement of the sewage sedimentation tank, the device is beneficial for carrying out sedimentation on sludge inside sewage; through the arrangement of a stirring mechanism, the device is beneficial for carrying out dosing stirring treatment on the sewage after sedimentation, the device is convenient for sufficient stirring, and insufficient stirring is avoided, and the device cannot react with liquid sufficiently; through the arrangement of a movable bottom cover and a back-and-forth adjusting mechanism, the device is beneficial for carrying out back-and-forth control on the bottom cover, so that a next step is performed after the sewage firstly reacts with the liquid sufficiently, and insufficient sewage treatment caused by step jumping is avoided; through the arrangement of a buffer board and a buffer hole, the device is beneficial for buffering sewage, a filter screen is prevented from being impacted directly to cause breaking of the filter screen; and through the arrangement of a vibrating mechanism, the device is beneficial for vibrating the filter screen, and the filter screen is prevented from being blocked to influence the filter effect.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment filter device. Background technique [0002] Water pollution is water that pollutes the environment by reducing or losing the use value of water caused by harmful chemicals. Acids, alkalis, oxidants, copper, cadmium, mercury, arsenic and other compounds in sewage, benzene, dichloroethane, ethylene glycol and other organic poisons, can poison aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition to produce unpleasant gases such as hydrogen sulfide and mercaptans, which further deteriorate the water quality. There are different classification methods for wastewater from different perspective...

AI Technical Summary

Problems solved by technology

[0003] There are some problems in the existing sewage treatment equipment. The stirring on the sewage treatment equipment is insufficient, the sterilization area is small, it is difficult to operate, time-consuming and laborious, and the static filtration is generally used for filtration. The static filtration speed is slow and the efficiency is low, which is not conducive to chemical industry. Large scale filtration of sewage
