Test method for ultraviolet dosage of overflow UV sterilizer

UV disinfection techniques have their advantages such as broad spectrum, fast, energy saving, no bistrois, etc., has been widely used in municipal water supply, drinking water disinfection, sewage treatment, and many fields such as food industry, electronics industry, pharmaceuticals. It is reasonable or not, the use effect is good, directly related to the health and safety of the public.

my country has also developed a lot of standards related to UV applications for the characteristics of different industries. like

1. According to the CJ / T204-2000 "Life Drinking Water UV Savory Surface", the sterilizer product of the new lamp is required, and the measured ultraviolet irradiation is not less than 12,000 μW • S / CM2. The ultraviolet irradiation dose measured by the normal working sterilizer shall not be less than 9000 μW • S / CM2.

2, according to GBT19837-2005 "City to Drainage UV Disinfection Equipment": Town Life Drinking Water Treatment UV irradiation dose is not less than 40mJ / cm2; urban sewage (1 grade A standard) sterilization treatment UV radiation dose is not less than 20MJ / CM2; urban sewage (1 stage B and 2 standard) sterilization treatment of ultraviolet irradiation dose of not less than 15 mJ / cm2.

3, according to the requirements of GB50014-2006 "Outdoor Drainage Design Specification", the second-stage treatment of water-proof the water is 15 to 22 mJ / cm2; the ultraviolet irradiation dose of the reclaimed water is 24 to 30 mJ / cm².

The core parameters in the standard - ultraviolet irradiation dose, is the integral function of UV radiation intensity (I) and the time(T) to stay in the sterilizer during the sterilizer flow through the sterilizer. Usually expressed in dose,

That is: dose =IT (unit: mj / cm²)

The I is the ultraviolet radiation intensity of the lamp, the water is specifically flowed through the path in the bactericidator, the ultraviolet transmittance of water, the water particles, the transmission of the sleeve and the degree of fouling the sleeve wall. Impact, it is difficult to calculate it. And engineering we need a simple way to verify our design and manufactured bactericia, whether relevant national and industry standards are met to achieve the expected bactericidal effect.

Let's take a brief introduction to this method.

Referring to the requirements of GB / T 1937-2005, the specific operation method of the biological verification method is: 1, first use the parallel ultraviolet beam to measure the water sample with the ultraviolet rays of different radiation intensities, test the microbiology under different UV doses. The activity is obtained, and the corresponding relationship curve between the microbial inactivation rate and the UV dose is obtained. 2. Continuous flow of the same test water through the ultraviolet sterilizer, change its flow, monitor the microbial residual concentration of the stock outlet under different flow rates, resulting in the corresponding curve of the sterilizer flow and the microbial inactivation rate. 3. Configuring the inactivation rate and ultraviolet dose measured by parallel ultraviolet beams, we can know the equivalent ultraviolet dose that the sterilizer can provide at a certain amount of flow.

If we measure a biological verification method, the equivalent ultra-dose value of a sterilizer is greater than the relevant national or industry standard, we can know that the bactericidator can meet the sterilization requirements in the current situation. However, since the ultraviolet lamp is attenuated during use, the surface fouling of the sleeve affects the transmission of ultraviolet light, and we should leave the initial ultraviolet dose of the sterilizer(UV sterilizer for drinking water with 254nm UVC germicidal lamp) to make the sterilizer on the lamp. The end of the tube life can still meet the requirements of sterilization performance. Its calculation formula is:

ED = ND * CLH * CJG

ED: Efficient dose of ultraviolet sterilizer

ND: Equivalent UV dose measured by a new lamp new casing state

CLH: aging coefficient of ultraviolet lamp

CJG: The scale factor of the sleeve
