Rural water to ultraviolet sterilizers require short contact time for sterilization, high sterilization efficiency, strong broad-spectrum, and do not change the physical and chemical properties of water. They also do not produce odors or other harmful byproducts such as halogenated hydrocarbons; In terms of work performance, it will not be affected by water temperature, and the equipment will not produce noise or corrode during operation. It has a small footprint, safe and reliable operation, and easy maintenance.

Compared to ozone sterilizers, ultraviolet sterilizers have the advantages of low energy consumption, no large mixers, and no fishy smell. They not only have a good sensory experience, but also reduce operating costs. Next, the editor will briefly introduce common disinfection methods for drinking water:

1. The water plant chooses the composite chlorine dioxide disinfection mode: Due to the instability of ozone in water, it is easy to decompose into oxygen. If ozone disinfection is used in the water plant, after staying in the clean water tank, the remaining ozone in the water has been completely decomposed, and the disinfection in the pipeline network cannot be guaranteed. Therefore, if ozone disinfection is used for water supply in the water plant, it needs to be used in conjunction with other disinfectants to maintain the continuous disinfection ability in the pipeline network. Chlorine dioxide has higher stability than ozone, and the residual amount of chlorine dioxide can last for a long time in the pipeline network. Therefore, for water plants with relatively long water supply pipelines, chlorine dioxide disinfection mode is adopted, and a composite generator of hydrochloric acid and sodium chlorate is selected as the reactant. One important reason for choosing a composite chlorine dioxide generator is that it generates a mixed gas containing chlorine dioxide and chlorine gas. When conducting disinfection tests on water samples with different COD contents, no trichloromethane was detected. This indicates that the combination of chlorine dioxide and chlorine gas in the disinfection process can suppress the formation of trichloromethane, reduce the amount of chlorine dioxide used, and lower disinfection costs.

2. Selecting membrane electrolysis ozone disinfection mode for local water supply: Due to the special nature of raw materials required for chlorine dioxide disinfection and the strict preparation process, considering the comprehensive management level of local water supply, ozone disinfection is more operable than chlorine dioxide disinfection. The water source well is relatively close to the end of the user, and the disinfected water is quickly transported to the user. The circulation and turnover of drinking water are fast, so the requirement for continuous disinfection in water supply is not very high. According to the results of groundwater quality testing, the drinking water source is between 8.5-9.0 and does not contain bromide ions. The use of ozone disinfection will not produce bromoform and other brominated disinfection by-products. Therefore, the local water supply project adopts the membrane electrolysis ozone disinfection mode with simple management and high safety.

If rural water is converted to ultraviolet sterilizers for drinking water, it will be safer and will not have adverse effects on the human body due to excessive use of pesticides. Rural water to ultraviolet sterilizer, compared to traditional ozone sterilizers, has the advantages of low energy consumption, no large mixer, and no fishy smell. It not only has a good visual experience, but also reduces operating costs.
