Domestic wastewater rapid treatment device utilizing ultraviolet ray sterilization

Abstract

The invention discloses a domestic wastewater rapid treatment device utilizing ultraviolet ray sterilization. The domestic wastewater rapid treatment device utilizing ultraviolet ray sterilization comprises a tank body and a sedimentation tank, wherein the upper part of the tank body is fixedly provided with two filtering plates the outer diameters of which are adaptive to the inner diameter of the tank body; the two filtering plates are in semispherical structures; the openings of the semispherical filtering plates are formed upward, and a filter core made of a fiber ball filter material is arranged between the two filtering plates; the outer side wall of the tank body is provided with a water intake pipe positioned above the filtering plates; an ultraviolet ray light emitting body is arranged in the middle of the tank body; a stirrer is arranged at the lower part of the tank body; the side wall of the lower part of the tank body is provided with a bleaching powder injection opening; the sedimentation tank is communicated with the lower part of the tank body. The domestic wastewater rapid treatment device utilizing ultraviolet ray sterilization, which is provided by the invention, can rapidly kill bacteria in wastewater rapidly so as to achieve the aim of treating wastewater rapidly.

Description

technical field [0001] The invention relates to a sewage environmental protection treatment equipment, in particular to a domestic sewage rapid treatment device for ultraviolet sterilization. Background technique [0002] At present, the discharge of urban domestic sewage is the main pollution source of urban water in China. Urban domestic sewage treatment is the top priority in the current and future urban water conservation and urban water environment protection. This requires us to focus on the construction of domestic sewage treatment facilities. As an important part of urban infrastructure, it is an urgent matter.
