Domestic sewage treatment device capable of sterilizing quickly

Abstract

The invention discloses a domestic sewage treatment device capable of sterilizing quickly. The domestic sewage treatment device comprises a precipitating and filtering tank and a sterilizing tank, wherein two partition plates are arranged at the upper part of an inner cavity of the precipitating and filtering tank, the two partition plates are in through connection through a filtering pipe, the inner cavity of the precipitating and filtering tank is divided into a water outlet cavity and a water inlet cavity by the two partition plates, a water inlet pipe is in through connection to the top end of an inner lateral wall of the water inlet cavity, a sewage draining hole is formed in a bottom wall of the water inlet cavity, one lateral end of the water outlet cavity is in through connection to the sterilizing tank through a connection pipe, a water pump is arranged on the connection pipe, an air inlet tank is arranged on a top wall of an inner cavity of the sterilizing tank, a stirring rod is arranged in the sterilizing tank, a plurality of stirring pipes are evenly in through connection to the stirring rod, and a chemical tank is arranged at the upper part of one lateral end of the sterilizing tank; the chemical tank is mutually matched with the stirring rod, a stirring blade and a stirring pipe to atomize sterilizing liquid, the sterilizing liquid can be quickly mixed with sewage, the quickly sterilizing purpose is achieved, water quality processing speed and quality are improved, and effects of domestic sewage to the surroundings are remarkably reduced.

Description

technical field [0001] The invention relates to a domestic sewage treatment device, in particular to a domestic sewage treatment device capable of rapid disinfection. Background technique [0002] Sewage produced in the process of human life is one of the main sources of water pollution. Domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life, and most of them are non-toxic inorganic salts. Sewage produced in the process of human life is one of the main sources of water pollution. Mainly feces and washing sewage. Mainly feces and washing sewage. Domestic sewage contains a large amount of organic matter, such as cellulose, starch, sugar and fatty protein; it also often contains pathogenic bacteria, viruses and parasite eggs; inorganic salts such as chloride, sulfate, phosphate, bicarbonate and sodium, Potassium, calcium, magnesium, etc. The general feature is high nitrogen, sulfur and phosphorus c...
