Sewage treatment device capable of automatically cleaning filter screen

Abstract

The invention discloses a sewage treatment device capable of automatically cleaning a filter screen. The sewage treatment device comprises a machine body, wherein a working cavity is formed in the machine body; a precipitation assembly for precipitating large particles in the sewage is arranged in the working cavity; the precipitation assembly comprises an inverted L-shaped sliding plate which isconnected with the inner wall of the left side of the working cavity in a front-back sliding manner; rotating shafts extending front and back are rotationally connected to the inner walls of the frontand back sides of the working cavity; when the device works, the device works, particles in the sewage can be quickly settled through the settling assembly; sewage and sediment can be controlled to fall down through the switch assembly; the cleaning assembly can be used for cleaning sediments on the filter screen to prevent blockage, the purification assembly can be used for accelerating the removal of peculiar smell of treated sewage, the detection assembly can be used for detecting to enable qualified water to enter a collecting box, otherwise, the qualified water enters the water inlet boxagain, the treatment efficiency is improved, the treatment effect is enhanced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the related technical field of sewage filter nets, in particular to a sewage treatment device for automatically cleaning the filter nets. 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. Domestic sewage has a strong odor, and direct discharge of the surrounding environment will pollute the environment and endanger human health. When the sewage is treated in the existing device, the filter screen is easily blocked by the residue and impurities contained in the sewage, which affects the sewage treatment efficiency, and The effect of sewage treatment is poor, and the treated water cannot be identified as qualified, and there may be sewage that is still harmful after treatment, affecting people's lives. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned technologies, the present...
