Problems solved by technology
At present, chlorine is widely used as a disinfectant in China, but the existence of disinfection by-products poses a potential threat to the water quality safety and ecosystem of reclaimed water
As an alternative product, chlorine dioxide can overcome the problem of disinfection by-products, but it is expensive and inconvenient to use
It is difficult for the actual reactor to meet the above conditions, resulting in the inhomogeneity of the fluid cells receiving ultraviolet radiation, which affects the disinfection effect

The invention relates to an open-channel type ultraviolet disinfection device. The open-channel type ultraviolet disinfection device comprises a baffle plate, a primary disinfection channel, a secondary disinfection channel, an automatic cleaning device, a reflecting cover, an ultraviolet intensity sensor, a water level sensor and a control module, wherein a light cup, an ultraviolet light bulb and a mirror housing are arranged in the primary disinfection channel; an ultraviolet lamp tube and a quartz socket tube are arranged in the secondary disinfection channel; the automatic cleaning devicecomprises a cleaning solution filling pipe, a sealing cleaning ring, a motor-driven device and a cleaning ring mounting plate. According to the open-channel type ultraviolet disinfection device disclosed by the invention, a convex lens is utilized to concentrate scattered ultraviolet rays into parallel light, so that the luminous intensity is enhanced and the utilization rate of ultraviolet lightis improved; in addition, treated sewage passes through an ultraviolet light wall from bottom to top, so that the irradiation time of an ultraviolet lamp is prolonged and treated wastewater is fullymixed by the baffle plate. By means of the secondary disinfection channel, the influence of the flow of the treated wastewater on ultraviolet disinfection efficiency is effectively avoided; moreover,the treated sewage is subjected to secondary disinfection so as to kill bacteria as much as possible.
Description
technical field [0001] The invention relates to the technical field of sewage disinfection treatment, in particular to an open channel ultraviolet disinfection device. Background technique [0002] Disinfection is the last process of sewage regeneration treatment, and it is also the most important barrier to ensure the reuse of sewage and public health safety. At present, chlorine is widely used as a disinfectant in China, but the existence of disinfection by-products poses a potential threat to the water quality safety and ecological system of reclaimed water. As an alternative product, chlorine dioxide can overcome the problem of disinfection by-products, but it is expensive and inconvenient to use. As a safe, reliable, economical and convenient disinfection method, ultraviolet disinfection has been paid more and more attention, and has been applied to the disinfection treatment of urban sewage and drinking water. [0003] After the bacteria are irradiated by ultraviolet...
