FMZX-80 UV sterilization instrument 4

UV disinfection www.gyxdq.com www.gyzwx.com13833174989 widely used in environmental protection, water industry, electronics, food, cosmetics and other industries Water disinfection, disinfection after the health and epidemic prevention departments identified, kill bacteria in water 99 %, use and maintenance easy, now has caused the majority of users of all ages. The product information as follows: First, UV disinfection Introduction: UV disinfection overcome the shortcomings of the existing traditional sterilization techniques. In the sterilization process, do not add any chemicals, does not produce any harmful substances or leave in the water, safe, reliable, installation, maintenance is simple, especially low investment and operating maintenance costs and excellent bactericidal effect. Second, in the form of UV sterilizer ultraviolet disinfection structure by the water in the form of a closed state; by type of ultraviolet light position underwater, underwater lamp type must be used outside the quartz tube to separate the water and lamps. 1. Closed Pressure cylinder requirements: UV disinfection Pressure cylinder enclosed stainless steel (304), and the inner surface do polished to enhance the ability of UV light reflection to improve the effective utilization of the ultraviolet light source. 2. quartz tube requirements: ultraviolet disinfection using high purity quartz tube, UV transmittance greater than 90%, and long-term bear more than 0.45 MPa working pressure. 3. Requirements for ultraviolet light sources: should be used straight tubular quartz UV low pressure mercury lamp. The technical requirements should be consistent YY / Tl060 -94 "straight tube-shaped quartz low pressure mercury ultraviolet light disinfection" requirement. When the radiation intensity is lower than the standard value of 70% of the factory should be considered stale light. Third, ultraviolet disinfection and water quality conditions to determine: 1, ultraviolet disinfection water quality standard describes the principles of water quality conditions determined mainly two: First, to reduce the water absorption of ultraviolet light; the second is to ensure that water quality meets drinking water standards. Color, turbidity, iron and manganese content in the water all affect the water absorption of ultraviolet light, so to restrict its value mainly to meet drinking water standards. After the water content of the E. coli bacteria and disinfection before the main consideration content and disinfection should be achieved. GB3838 a 88 "surface water quality standards" and "drinking water standards" set forth CJ3020 -95 as a centralized drinking water source of water should be less than 10 000 total coliform / L. However, the actual after coagulation, sedimentation, filtered and treated E. coli values ??are generally less than 1000 / L. Bacteria are smaller than 3000cfu / ml. Press inactivation rates of E. coli bacteria was 99% and 99.9%, the total number of bacteria effluent is 30cfu / mL E. coli l a / L, were less than 100cfu / mL and 3 / L standard value. 2, ultraviolet disinfection of water quality conditions of the experiment showed that the water quality impact of water on the UV absorption, it is necessary to carry out effective water quality control to ensure that the effect of UV disinfection.
