For surface water, drinking water Sanya, Hainan during UV disinfection disinfection of drinking water as before, generally after coagulation, sedimentation, filtration and other treatment. GB5749-85 "drinking water health standards" requirement in Sanya, Hainan after UV disinfection of drinking water purification for drinking water sources that the total coliform value should not be greater than 1 000 / L. Sanya, Hainan drinking water UV disinfection of treated surface water is purified, city buildings tank or a secondary water supply, can be used as sources of drinking water supplied directly to the water, the water quality should meet the drinking water health standards of the relevant provisions. Sanya, Hainan drinking water UV disinfection bacteriological indicators that can take total coliforms less than 1 000 / L, total bacterial count of less than 2 000 / mL, chroma less than 15 degrees, the total iron content of less than 0.3mg / L, turbidity of less than 5 degrees. 2.2 UV disinfection of drinking water Sanya, Hainan working conditions of ambient temperature, UV disinfection of drinking water in Sanya, Hainan radiation intensity UV light, thus affecting disinfection disinfection. Temperature 5 ℃ ~ 40 ℃ range of drinking water disinfection, UV disinfection Sanya effect changes with decreasing temperature, UV light output will be reduced below 5 ℃ even cause difficulty in starting the lamp. UV disinfection of drinking water in Sanya, Hainan Province, the lamp in a quartz tube package, in addition to its role in Sanya, Hainan prevent drinking water UV disinfection lamp rupture pollute the water, there are also reduced because the water temperature is too low impact on the efficiency of the UV lamp function. Therefore, the drinking water UV disinfection Sanya water temperature and ambient temperature is above 5 ℃. UV disinfection of drinking water Sanya, Hainan working environment relative humidity should be less than 65%, the maximum not more than 90%. High relative humidity, severe deterioration of the electrical components of the operating conditions, and the air, the small droplets increases, block UV intensity of the radiation decreases. Of the grid frequency is 50Hz. When the supply voltage changes, UV disinfection of drinking water in Sanya, Hainan radiation intensity UV lamp voltage increases and enhanced UV disinfection of drinking water in Sanya, Hainan's ability to increase. Sanya, Hainan UV disinfection of drinking water supply voltage should be stabilized at 220V ± 10% range, in which the supply voltage fluctuation range, the sterilizer disinfection capacity will be between 15% to 20% of the variation. 2.3 Sanya, Hainan UV disinfection of drinking water disinfection capability disinfectant Sanya, Hainan UV disinfection of drinking water disinfection capability refers to the case in the nominal amount of water to kill microorganisms in water features. Sanya, Hainan UV disinfection of drinking water disinfection capacity of its physical expression represents the state of the irradiation dose: radiation dose = radiation intensity X sterilizer effective water volume (L) / sterilizer rated into the water × 3.6 OK Sanya, Hainan UV disinfection of drinking water disinfection capability is the core issue of how to determine the radiation dose. Killing microbes require different type of irradiation dose, and the microorganism is present in a wide variety of water. Sanya, Hainan selected ultraviolet disinfection of drinking water radiation dose is too high will waste unnecessary energy, too low and reach the purpose of disinfection. Disinfection of water via the water should be focused on killing bacterial disease, generally considered Sanya UV disinfection of drinking water can be provided not less than the minimum irradiation dose 9 000μW / (cm2 · s), factory should be greater than 12 000μW / (cm2 · s). Sanya, Hainan in the drinking water UV sterilizer, UV radiation intensity of each point is different. UV lamp emitted through the quartz tube cause some attenuation of the intensity passing through the water layer with the water depth increases. UV disinfection of drinking water in Sanya, Hainan how only the case of lamps, ultraviolet radiation within the cylinder cross-section intensity distribution is more complex calculations to ensure that each point strength is broadly consistent with the structural design of the primary problem. UV disinfection of drinking water Sanya, Hainan effective use of the process, increasing the radiation dose is reduced over time, mainly because of UV disinfection of drinking water in Sanya, Hainan lamp radiation intensity changes, UV disinfection of drinking water tube Sanya, Hainan the body surface and the quartz sleeve fouling caused by ultraviolet reflectivity and transparency purple is also an important reason for lower. UV disinfection of drinking water Sanya, Hainan effective usage time of the lamp is its radiation intensity from the factory standard value dropped by 30% cumulative time, UV disinfection of drinking water in Sanya, Hainan effective life of the lamp should be up to 13000h. UV disinfection of drinking water Sanya, Hainan specified by the manufacturer in proximity useful life, should strengthen the monitoring of water quality, timely replacement of failed lamps. In actual operation, where necessary, the use of the standard value of the lamp failure, appropriate reduction of UV disinfection of drinking water in Sanya, Hainan into the water to ensure the necessary radiation dose, you can still obtain satisfactory water quality. 2.4 microorganisms by ultraviolet light irradiation resurrection in Sanya, Hainan UV disinfection of drinking water, a variety of different microorganisms are as ultraviolet radiation damage and even death. However, all of any biological ability to repair damage to a certain microbial no exception. Microbial UV damage can be reversed by visible light is called resurrection, effective 330nm ~ 480nm wavelength range includes the visible and near UV. Repair of microbial species and due to hit by ultraviolet extent varies. Some lack the enzyme microorganism matt light resurrection resurrection capability. UV fluence increases, photoreactivation rate decreased when the dose reaches 60 000μW/cm2, the E. coli photoreactivation disappear. Photoreactivation mechanisms are: the action of the enzyme photoreactivation, connected together can be reversed photoproduct formation of thymine dimers and monomers depolymerization, the DNA to restore normal function and structure of the DNA replication at the site of injury ignored and bypassed to achieve cutting repair and recombination repair. In order to avoid the phenomenon of photoreactivation, UV disinfection of drinking water in Sanya, Hainan should guarantee a certain dose of ultraviolet irradiation, sterilization should be installed in the tank outlet pipe, after disinfection of the water-box, to avoid prolonged contact with the light. 3 UV sterilizer Sanya, Hainan, Sanya, Hainan Monitoring System 3.1 UV sterilizer lamp UV radiation intensity in Sanya, Hainan ultraviolet radiation intensity ultraviolet disinfection with ultraviolet radiation intensity was determined by measuring, the instrument shall be approved by the national legal units calibrated and the calibration validity period.
