Abstract

The invention discloses a municipal discharged sewage disinfection and decolorization device, which comprises a disinfection tank, the bottom of the disinfection tank is provided with an upward concave conical part, the bottom of the conical part is provided with a vertical pipe communicated with the interior of the disinfection tank, and the upper surface of the conical part is fixedly provided with waterproof ultraviolet sterilization lamps which are annularly distributed at equal intervals. The top of the disinfection tank is of an opening structure, a flange ring is arranged at the opening position of the top of the disinfection tank, a plug cap is arranged at the bottom of the vertical pipe, a liquid drainage pipe is arranged at the bottom position of the side wall of the vertical pipe, a blow-off pipe is arranged at the bottom position of the side wall of the disinfection tank, and an annular net plate is arranged at the top position of the inner wall of the vertical pipe. A filter cartridge is inserted into the inner wall of the annular net plate, and an annular block is welded to the lower end of the filter cartridge. According to the invention, sewage can be filtered, a certain decoloration effect is achieved, water can be disinfected, part of water reversely impacts the annular screen plate, the screen plate is prevented from being blocked, and a self-cleaning effect is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a disinfection and decolorization device for municipal sewage discharge. Background technique [0002] Municipal sewage, the water quality is relatively stable, but turbid, deep and foul-smelling, slightly alkaline, high in nitrogen and phosphorus, and generally does not contain toxic substances. At the same time, domestic sewage is very suitable for the reproduction of various microorganisms, so it often contains a large number of bacteria (including Pathogens) viruses and parasite eggs, this kind of sewage has good biochemical properties and is relatively easy to treat. Municipal sewage treatment water is a water source with great changes in water quality and very difficult to treat. The concentration of total dissolved solids, COD, BOD, silicon, ammonia and some other pollutants changes very frequently. In addition, the sewage before treatment Contains high concentra...
