The sterilization principle of ultraviolet light is to use the energy of ultraviolet light to destroy the DNA of various viruses, bacteria, and other pathogenic bodies in water. Ultraviolet light penetrates the cell membrane and nucleus of microorganisms, destroys the molecular bonds of nucleic acids, and causes them to lose their replication ability or activity and die. The ultraviolet sterilization band is between 200-300nm, with the 253.7nm band having the strongest ability.

UV disinfection technology has the advantages of safety, efficiency, low cost, and no by-products. After UV disinfection, there is no secondary pollution or by-products, and the effluent can be reused for irrigation in farmland, forest land, or underground water injection, achieving resource utilization.

The small-scale township domestic sewage treatment equipment and integrated open channel ultraviolet disinfection equipment are made of 304 stainless steel, integrating the open channel, ultraviolet disinfection module, effluent control system, and self-control system, and equipped with a Babbitt metering tank. The integrated UV equipment is convenient for customers to install and use, and has low civil engineering requirements. The ultraviolet disinfection lamp adopts imported low-voltage high-strength ultraviolet lamp with a lifespan of up to 12000 hours. The ballast adopts German technology and has instantaneous overvoltage protection, which can effectively extend the lifespan of the lamp.

Characteristics of small township domestic sewage treatment equipment

• Central permanent magnet cleaning system, lightweight, well sealed, evenly stressed, and stable in operation;
• High equipment integration, including UV disinfection system and pasteurization tank;
• The equipment does not require civil construction and has a short production cycle;
• The device only needs to provide an inlet and outlet interface, which is easy to install and operate;
• The manufacturer consolidates the work of the design institute, civil construction, and equipment installation parties.

Application scope of small-scale township domestic sewage treatment equipment

Mainly used in small-scale sewage treatment plants, township sewage treatment plants, sewage disinfection and reuse disinfection, etc.
