Beijing UV disinfection

Beijing ultraviolet disinfection effect: The target price is calculated by UV disinfection of fecal coliform kill rate in most drinking water systems, ultraviolet disinfection and sterilization in addition to fecal coliforms and many other organisms. Choose fecal coliform as an ultraviolet disinfection sterilization target is mainly due to: 1, which is the most common research goal ultraviolet sterilization of bacteria; 2, it has a reliable standard measurement method; 3, fecal coliform water purification target organisms systems; 4. Select fecal coliform as an ultraviolet disinfection sterilization objective findings can provide a reference for comparison with other methods of sterilization of microorganisms. 254 nm UV transmittance, turbidity, total suspended solids (TSS) concentration, an important factor in these parameters also affect UV disinfection sterilization effect. At the same time we calculate fecal coliform kill rate can be calculated UV disinfection power and the calculated power UV disinfection UV disinfection can determine the basic price of. Beijing ultraviolet disinfection description: Beijing ultraviolet disinfection and other reactor tube spacing should be in accordance with the desired dose fushe lamp power and maintenance requirements identified. Lamp spacing should not be too close, to avoid the ambient temperature is too high and affect luminous efficiency. At the same time, the lamp spacing should not be too far away, to ensure that the irradiation intensity of UV disinfection. During the actual treatment, the water flow is constantly changing. Should therefore be based on the range of possible changes in flow, the use of automatic control device fushe processing power flow is controlled according to the size of the flow. Avoid ultraviolet disinfection produces disinfection fushe insufficient or due to lack of traffic leaving the lamp overheating. If no further dosing of disinfectants, UV disinfection were sterilized water residence time in the pipeline should not exceed 3 ~ 5h. Water distribution system should be designed to ensure that the appropriate data or consider cycling measures. From the perspective of the water treatment process to consider the general aspects of UV disinfection disinfection are mostly located in the final stages of the purification process. To avoid microbial fushe ultraviolet light after the reactivation and proliferation produce, after ultraviolet disinfection device from water point to water pipes should be opaque material. UV disinfection system before initial operation and after long outage restart, should the use of chemical disinfectants on equipment and piping systems thorough disinfection. Ultraviolet disinfection system powered devices to consider all fushe unit module supply data show, shigubaojing, work accumulated time display and control switch, just the power supply voltage fluctuation range of more than 5%, could be considered the regulator or regulator device. Unstable voltage will affect lamp life, low voltage will affect the luminous power, influence bactericidal effect (usually low pressure lamps supply voltage fluctuations up and down at 10 percent, sterilization capability of the lamp is between about 15% to 20% change ). The lamp power supply security considerations usually associated with standard power supply system the same standard, ultraviolet disinfection to consider backup power and leakage, electric shock protection devices. For ultraviolet disinfection water treatment device smaller terminal disinfection, consider using water start automatic power hoist system to save energy, but to consider the impact of power frequently start working life of the lamp. Often before the actual ultraviolet disinfection reactor pressure set to adapt to the band limiting device, and install UV probes to detect fushe intensity, when devices are more inconvenient and reactor management, according to the signal should be configured to automatically shut off the flow of manipulation institutions in order to ensure water safety. Conditional project should be realized ultraviolet disinfection device automated operation. Another important application of UV disinfection disinfection technology Beijing is the regeneration disinfection, also had the most stringent sterilization standard process flow for a class. Drinking water, high-rise buildings, yiyuan, storage tank factory; production of water food and beverage industry, as well as rivers, lakes and underground for the water supply system, are required to install an ultraviolet disinfection treatment Beijing
