The open channel ultraviolet sewage disinfection system is mainly used for disinfection in municipal sewage treatment plants, community sewage treatment, reclaimed water reuse, and industrial sewage disinfection. According to different usage and structural characteristics, it can be divided into horizontal channel type and vertical channel type, and the water level control method can be divided into three types: overflow weir outlet method, non powered flap gate water level control method, and electric weir gate control method.
The entire ultraviolet disinfection system mainly includes the ultraviolet disinfection module, automatic control center, power distribution center, automatic cleaning system, water level control system, and auxiliary equipment.

UV disinfection module
Adopting a low water resistance UV disinfection module to achieve smaller water resistance and higher reliability. Each standardized ultraviolet disinfection module consists of a stainless steel lamp frame, ultraviolet lamp tube, quartz sleeve, cleaning structure, power distribution system, and data acquisition system. The entire ultraviolet disinfection system is composed of several ultraviolet disinfection modules, which are easy to install, operate, and maintain.

Technical characteristics of ultraviolet disinfection module
1.The module structure with low water resistance has lower water resistance and less water level change before and after disinfection compared to traditional module structures.
2Waterproof grade meets the requirementsIP68Grade standards are applicable to situations with strict requirements.
3Multiple sealing and waterproof treatment, the quartz tube is tightly installed and will not fall off due to friction during automatic cleaning.
4Add sealing rings to the cable section to effectively prevent short circuit damage to the lamp caused by water ingress into the cable.
5. Made of high-quality corrosion-resistant stainless steel material, the lamp tube and signal cable are sealed inside the disinfection module and will not be exposed to sewage and ultraviolet light.
6Provide each module according to different situations such as customer processing water volume, water quality, and sterilization requirements3Support to20Multiple designs for supporting lights.

★ UV lamp
One of the core components of the ultraviolet disinfection system is the ultraviolet lamp tube. Our company's ultraviolet lamp tube is a world-class low-voltage and high-strength ultraviolet lamp tube, installed in a quartz sleeve on the module, parallel or perpendicular to the direction of water flow. The effective working life of the lamp tube is9000~12000Hours, the maximum power of a single lamp can reach250-320WThe ultraviolet sterilization lamp adopts imported low-pressure and high-temperature solid mercury alloy technology to ensure its service life9000hour.

★ Quartz casing
Quartz sleeve installed on module bracket, quartz tubeUVCTransmittance greater than or equal to85%One end is a closed end and the other end is an open end. Through multiple sealing designs, the protection level isIP68Effectively prevent water from seeping into the quartz sleeve and affecting the normal operation of the ultraviolet lamp. Adopting high transmittance（UVT）Quartz tube: High quality quartz tube is selected to ensure excellent ultraviolet penetration and the highest intensity of ultraviolet output.

★ Electronic ballast module
The electronic ballast is the core component of the entire system, and the prominent advantage of the UV disinfection system is the stability of the electronic ballast. By introducing globally leading German technology manufacturing, it has instant high-voltage start of ultraviolet lamps and efficient variable power outputandPLC3Microelectronics controlled ballast technology. The electronic ballast is installed inside the ballast cabinet or module chassis. Made of high-quality corrosion-resistant stainless steel material, the lamp tube and signal cable are sealed inside the disinfection module and will not be exposed to sewage and ultraviolet light.20Provide each module according to different situations such as customer processing water volume, water quality, and sterilization requirements

alarm system
When a fault occurs, the alarm device can indicate to the user what type of fault and its location through sound, visual, and other means. The fault can be queried for several or more records.★ UV intensity monitoring systemEach module group has a set of ultraviolet intensity monitoring system, which includes ultraviolet probes

UV
Accessories such as intensity meters and UV probes are installed underwater to facilitate monitoring of scaling in quartz tubes and changes in UV lamp intensity.
★ Automatic cleaning system
The effectiveness of UV disinfection is often greatly affected by the scaling on the surface of quartz sleeves, resulting in a significant decrease in UV intensity.The Skewer brand UV disinfection equipment comes with a built-in cleaning system. This cleaning technology can automatically clean the surface of the casing online within any set time without affecting the operation of the equipment, with high efficiency and low friction without jamming, providing stable and efficient sterilization effect for the UV disinfection system.The automatic cleaning system is driven by compressed air and linked with the ultraviolet light intensity monitoring device for automatic cleaning, and can be easily manually operated

★ Water level control systemwater level sensorThe water level sensor is an effective and necessary means of self-protection for the lamp tube. Due to its high power, ultraviolet sterilization lamps must be naturally cooled by sewage. When exposed to air for a long time and lit up, the lamp may burn out due to insufficient heat dissipation. Therefore, it is necessary to ensure that the water level in the open channel can submerge all the lamps. However, the ultraviolet transmittance in sewage is low, and when the water level is too high, it can lead to unsatisfactory disinfection effect of the surface water layer. Therefore, the water level in the open channel cannot be too high. The water level sensor measures the water level value in the open channel online, ensuring that the water level in the channel remains within the designed range. When the water level in the open channel exceeds the set minimum for a long time
