Sewage treatment device for municipal environmental protection

Abstract

The invention relates to the field of municipal environmental protection equipment, in particular to a sewage treatment device for municipal environmental protection. The device comprises a vertically-arranged supporting and mounting cylinder, wherein an arc-surface bottom plate is arranged in the middle of the bottom of the supporting and mounting cylinder in an inwards-concave mode, a plurality of supporting and mounting columns are arranged on the edge of the bottom of the supporting and mounting cylinder at equal angles, a drainage pipe is arranged at the lower right corner of the supporting and mounting cylinder in an extending mode, a manual valve is arranged on the drainage pipe extending out of the supporting and mounting cylinder, and a spherical mesh enclosure is arranged at the upper end of the supporting and mounting cylinder. Sewage is filtered in advance, impurities are collected, the waste recycling efficiency is improved, the sewage treatment difficulty is reduced, the sewage treatment efficiency is improved, through a rotary flow guide structure and a pre-stirring structure, the liquid medicine can be diluted at first, then through an air compression structure and a uniform aeration structure, the liquid medicine is guided out uniformly, aeration treatment is matched, the effect of the liquid medicine is improved, and the sewage treatment efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of municipal environmental protection equipment, in particular to a sewage treatment device for municipal environmental protection. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. Municipal engineering research and teaching contents include engineering fluid mechanics, water supply and drainage theory, technology and facilities, urban wastewater treatment and reuse, sludge resource utilization technology, etc. Municipal work includes the treatment of various types of sewage. Before the sewage is treated, it needs to be filtered before it can be disinfected and other...

AI Technical Summary

Problems solved by technology

Existing sewage filtration equipment cannot simultaneously carry out disinfection treatment during filtration. In the later stage of disinfection, sewage disinfection powder needs to be mixed evenly with sewage, and the amount of sewage is often large, so it is difficult to mix evenly

[0003] Chinese patent (publication number CN108996746A) discloses a sewage treatment device for municipal environmental protection. Although the above-mentioned problems are improved, there are problems in the pretreatment of sewage, the pretreatment of medicinal liquid, the uniform mixing, and the aeration treatment. Defects, resulting in unsatisfactory efficiency and quality of sewage treatment
