Open channel type ultraviolet disinfection equipment for sewage treatment

Abstract

The invention discloses open channel type ultraviolet disinfection equipment for sewage treatment which comprises a plurality of ultraviolet disinfection lamps for sterilizing and disinfecting sewageand a plurality of supporting bases for supporting the equipment, a first driving piece for controlling an ultraviolet disinfection lamp to do lifting motion, a fixing device which is used for clamping and fixing the ultraviolet disinfection lamp, two vertical conveying belts which are used for driving the fixing device to drive the ultraviolet disinfection lamp to rotate, and a cleaning device which is used for automatically cleaning the ultraviolet disinfection lamp are arranged on each supporting base. Through the arrangement of the structure, the ultraviolet disinfection lamps can be effectively cleaned; the ultraviolet disinfection lamps are prevented from scaling to influence ultraviolet irradiation, the irradiation effect of the ultraviolet disinfection lamps is effectively guaranteed, the ultraviolet disinfection lamps can be efficiently replaced through the arrangement of the fixing devices, and damaged ultraviolet disinfection lamps can be replaced more easily in a labor-saving mode.

Description

technical field [0001] The invention belongs to the technical field of sewage disinfection treatment, and in particular relates to an open channel ultraviolet disinfection equipment for sewage treatment. Background technique [0002] The open channel ultraviolet disinfection equipment module is installed in the open ultraviolet disinfection channel. For the convenience of maintenance, the power distribution cabinet and control cabinet are installed above the water channel. The ultraviolet lamp tubes are arranged in the open channel, and the ultraviolet lamp tubes are arranged in parallel with the direction of the water flow. [0003] Now, the public document with the publication number CN107935107A discloses an open channel type ultraviolet disinfection device, which effectively increases the luminous intensity, improves the utilization rate of ultraviolet light, and increases the irradiation time of the ultraviolet lamp. The board makes the treated wastewater fully mixed; ...

Problems solved by technology

[0003] Now, the public document with the publication number CN107935107A discloses an open channel type ultraviolet disinfection device, which effectively increases the luminous intensity, improves the utilization rate of ultraviolet light, and increases the irradiation time of the ultraviolet lamp. The board makes the treated wastewater fully mixed; it effectively avoids the impact of the treated wastewater flow on the ultraviolet disinfection efficiency, and at the same time performs secondary disinfection on the treated sewage to kill as many bacteria as possible, and solves the problem of insufficient ultraviolet dose and insufficient disinfection. Thoroughly, the problem of bacterial resurrection

[0004] However, after the ultraviolet disinfection device is used underwater for a long time, a large amount of dirt is covered on the ultraviolet disinfection lamp tube, which affects the irradiation of the ultraviolet disinfection lamp tube, and if the ultraviolet disinfection lamp tube is damaged, it cannot be carried out with a simple ultraviolet lamp tube It's inconvenient to replace
