Sewage treatment equipment with good filtering and purifying effects

Abstract

The invention relates to the technical field of sewage treatment equipment, and discloses sewage treatment equipment with good filtering and purifying effects. The sewage treatment equipment comprises a box body, and an opening and closing door plate is hinged to the front surface of the box body. According to the sewage treatment equipment with good filtering and purifying effects, sewage can conveniently enter the box body through a water inlet pipe, water guide inclined plates can conveniently guide the flow of the sewage, two rotating rods rotate in the box body through rotating motors and rotating bearings respectively so as to drive a roller and a crushing blade to rotate respectively, sundries and garbage such as wood chips, empty bottles and cloth pieces in sewage are rapidly smashed, and the blocking condition is avoided; a filter screen box rapidly slides into the position between two mounting bases through sliding grooves and sliding blocks to filter out impurities in the sewage, a handle pulls a stretching column and an inserting rod to stretch out and draw back up and down under the elastic force of a telescopic spring, the sliding blocks are fixed by inserting the inserting rods into inserting holes, so that the installation of the filter screen box is completed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to sewage treatment equipment with good filtering and purification effects. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollution. Sewage must be treated before it can be discharged. 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, Various fields such as petrochemical, environmental protection, urban landscape, medical care and catering are also increasingly entering the daily life of ordinary people.

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sewage treatment equipment with good filtration and purification effect, which has the advantages of crushing impurities and easy maintenance, and solves the problem that a large number of wood chips, empty bottles and cloth pieces will be included in the existing sewage discharge process. Such as debris and garbage, it is easy to cause blockage and jamming of sewage treatment equipment, so that the sewage filtration work cannot be carried out normally, and it is not convenient to clean the filter structure, which affects the filtration efficiency.
