UV sterilization mainly uses 254 nm ultraviolet light. Ultraviolet light of this wavelength, even with a small amount of ultraviolet radiation, can also destroy a cell's life core - DNA, thus preventing cell regeneration, losing the regeneration ability and making bacteria harmless, thus achieving sterilization effect. Like all other UV application technologies, the scale of this system depends on the intensity of the UV rays (the intensity and power of the irradiator) and the exposure time (the length of time that water, liquid, or air is exposed to UV rays).
B With the development of national economy and the improvement of people's living standards, on the one hand, China's drinking water sources are seriously polluted; On the other hand, the quality standard of drinking water has been greatly improved. It is easily affected by weather. In rainy seasons, ammonia, nitrogen COD、 The contents of iron, manganese, fluorine, bacteria, turbidity, etc. exceed the drinking water standard, the natural ecological environment is seriously damaged, and water resources are seriously polluted. The company professionally customizes water treatment scheme to ensure safe and healthy drinking water
The pollution of drinking water sources has led to the deterioration of drinking water quality and posed a threat to the health of urban residents. Among them, chemical pollutants will lead to human gene mutation, seriously affecting the overall quality of the population; Another important aspect is that a large amount of nitrogen and phosphorus nutrients are discharged into the water body, leading to eutrophication of the water body. The excessive reproduction of algae in the water body has seriously affected the purification effect of the waterworks. In China, soil erosion is serious and the concentration of natural organic matter in water is high, which also increases the difficulty of drinking water treatment.
