Novel filtering and sterilizing apparatus for domestic sewage

Abstract

The invention provides novel filtering and sterilizing apparatus for domestic sewage, and belongs to the field of domestic sewage treatment apparatus. The apparatus comprises an outer shell, a rotaryfiltering device, a flocculant device, a stirring device, an ozone deodorizing and sterilizing device, ultraviolet germicidal lamps, a large-particle collecting device and a large-particle cleaning device. According to the apparatus provided by the invention, the large-particle cleaning device and the rotary filtering device are arranged, so that the purposes that the domestic sewage is filtered,and a sewer pipeline is prevented clogging due to the larger amount of large-particulate matter in sewage are realized; an arc-shaped scraping blade, the large-particle collecting device and a semi-circular filter net are utilized, so that the automatic cleaning and garbage collecting function of the filtering device are realized, and the cleaning power of people is reduced; the flocculant deviceand the stirring device are arranged, so that the water quality can be effectively purified; and the ultraviolet germicidal lamps and the ozone deodorizing sterilizing device are arranged in a secondary sewage treatment sterilization deodorization cavity, so that microorganisms contained in water can be effectively killed, and the apparatus has high-efficiency effects of sterilization and deodorization.

Description

technical field [0001] The invention relates to a domestic sewage treatment device, in particular to a novel domestic sewage filtration and sterilization device. Background technique [0002] Domestic sewage refers to the waste water produced by urban authorities, schools, enterprises, institutions and residents in their daily life, including toilet excrement, laundry and bath water, household drainage such as kitchens, and drainage from commercial, hospital and playgrounds, etc.; in the process of human life The sewage produced is one of the main sources of pollution of water bodies; domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fat protein; it also often contains pathogenic bacteria, fat and parasite eggs; chlorides of inorganic salts, Sulfate, phosphate, bicarbonate, sodium, potassium, calcium, magnesium, etc., are prone to produce foul-smelling substances under the action of anaerobic bacteria; domestic sewage often conta...
