sewage Sterilization equipment The system is installed in the open ultraviolet sterilization and disinfection channel. This equipment uses GPHHA1554T6L/4P 320W high and low pressure ultraviolet high mercury lamp. The 320W sewage sterilization and disinfection lamp has the characteristics of long service life, rapid sterilization, and good effect. The ultraviolet disinfection system of open sewage channel is installed in the open disinfection channel, and the open channel disinfection module is placed in the open channel. All light tubes of each module can be designed as 4-8 light tubes, which are 10 cm away from each other in parallel, and arranged evenly to ensure that the water flow through the ultraviolet light tube module can be evenly exposed by the ultraviolet light, so as to ensure the complete and stable sterilization effect.
The sewage sterilization and disinfection equipment system is mainly used for disinfection of municipal sewage treatment or industrial sewage treatment, residential sewage treatment, reclaimed water reuse and industrial sewage disinfection. According to different service conditions and structural characteristics, it can be divided into horizontal channel type and vertical channel type. The water level control mode can be divided into overflow weir outlet mode, non power flap valve water level control mode and electric weir valve control mode.
