The application of ultraviolet disinfection equipment in secondary water supply.

Although the secondary water supply can reasonably consider the power supply requirements of multi story buildings in terms of water flow rate and pressure, the water output is reduced, and the difficult problem is that the indicators of intestinal pathogenic bacteria exceed the standard, and the potassium permanganate index is based on zero. In order to better improve the water quality of the secondary water supply system software, in addition to strengthening management and improving the raw materials and structure of the water storage tank, an effective way is to carry out secondary disinfection to solve the problem. At present, the key to water disinfection includes physical methods and organic chemical methods, and the common disinfectant in organic chemical methods is harmful gases. Taking into account the safety factor of the secondary water supply system software for housing and the prevention of disinfection by-products, various organic chemical disinfection methods are not suitable. Physical methods such as heat transfer medium, ultrasonic method, ultraviolet direct method, electromagnetic field, high-voltage electric field, and high-frequency field can all be used for sterilization and disinfection. Taking into full consideration the safety factor and originality of technical standards, the experiment selected the ultraviolet direct processing technology for the secondary water supply ultraviolet sterilizer. In recent years, overseas countries have attached great importance to the actual disinfection effect of drinking water ultraviolet sterilizers, especially after discovering the presence of cryptosporidium in drinking water. The disinfection process of domestic water ultraviolet sterilizers has long been regarded as the most important inspection data for drinking water disinfection, and will be announced to be included in the UK's power supply policy regulations.

The principle of the secondary water supply ultraviolet disinfection device;

1. Apply ultraviolet spectroscopy with a wavelength of 225-275 μ m and a maximum value of 254 μ m, which has high energy efficiency in water. It can destroy the nucleic acid structure of microbial strains and has strong antibacterial effects, thus achieving the purpose of disinfection.

2. The machine equipment can reasonably eliminate Escherichia coli, typhoid bacillus, Legionella, cold virus, hepatitis B virus, etc., Furthermore, clean the water body.

3. The diagnostic rate of viruses and bacteria in sea surface, water or other water quality solved by the UV water disinfection system software is over 99.99%.

4. UV sterilization is achieved by using a strong UV source to directly irradiate water. This type of purification equipment can quickly take effect without any residue or potential hazardous compounds.

5. The UV sterilizer adopts an integrated design scheme of control board and water CPU (if necessary, a professional design scheme can be developed to fit the body). The control board consists of a power circuit for indicating the operation of the ultraviolet sterilization lamp, a programmable controller for time control, a time total control board, and an electronic ballast. The ultraviolet sterilizer consists of a closed working pressure cylinder, inlet and outlet ports, a fully automatic cleaning waterproof sleeve, ultraviolet LED tubes, and upper and lower radiation source covers for the LED tubes.

3、 Application fields of secondary water supply ultraviolet sterilizer:

1. A water supply system that utilizes rivers, lakes, ponds, and river water as its water resources.

2. Water supply system for upper water storage tank, reserved water storage tank, and reserved water storage tank.

3. Production in the food, pharmaceutical, beverage, and liquor industries.

4. Various water supply systems that require sterilization and disinfection.
