Problems solved by technology

Due to the need for persistent disinfection capabilities, only chlorine disinfectants and chloramine disinfectants can be used for secondary disinfection, but at the same time, the use of these disinfectants generates harmful disinfection by-products, and the production of by-products increases with drinking increased storage time of water in the distribution network

Embodiment 1

[0039] Prepare stable hydrogen peroxide solution according to the formula of stable hydrogen peroxide disinfectant. The mass fraction of each component: hydrogen peroxide 14.3%, silver nitrate 0.0079%, sodium dihydrogen phosphate 0.12%, disodium hydrogen phosphate 0.0004%, the balance of distilled water. Wherein the mass percent content of the hydrogen peroxide active ingredient is 5%, and the silver ion content is 0.005%.

[0040] How to use: such as figure 1 As shown, disinfectants with good antivirus effects such as chlorine disinfection and ultraviolet disinfection are still used for primary disinfection, but stable hydrogen peroxide is used as secondary disinfectant to replace traditional chlorine disinfection, chloramine and chlorine dioxide and other chlorine-containing secondary disinfectants. grade disinfectant. When using stable hydrogen peroxide as a secondary disinfectant, it is necessary to neutralize the residual chlorine in the water with hydrogen peroxide aft...

Embodiment 2

[0044] The method for preparing stable hydrogen peroxide solution is the same as in Example 1.

[0045] How to use: such as figure 2 As shown, ultraviolet disinfection was used for primary disinfection, and stabilized hydrogen peroxide was used as secondary disinfectant. When using stable hydrogen peroxide as a secondary disinfectant, keep the hydrogen peroxide content in the water at 5-15mg / L. After the disinfection is completed, the residual amount of each component must meet the limit requirements stipulated by national laws or standards and must not exceed.

[0046] The advantage of this embodiment is that it completely avoids the use of chlorine disinfectants, thereby further reducing the generation of chlorine disinfection by-products such as trihalomethanes; it overcomes the disadvantage that chlorine disinfection is not effective for pathogenic microorganisms such as Giardia and Cryptosporidium . Compared with the example, this example needs to carry out certain mo...

Embodiment 3

[0048] The method for preparing stable hydrogen peroxide solution is the same as in Example 1.

[0049] How to use: such as image 3 As shown, in the primary disinfection, stable hydrogen peroxide is used as the primary disinfectant, stable hydrogen peroxide is used as the secondary disinfectant, the concentration is 30-40mg / L, and the disinfection time is extended as much as possible. Combined with ultraviolet disinfection, the effect is better. Pay attention to monitoring the remaining amount of disinfectant after the primary disinfection, and if it is insufficient, do a second dose to supplement it, so that the hydrogen peroxide content in the water is maintained at 5-15mg / L during the secondary disinfection. After the disinfection is completed, the residual amount of each component must meet the limit requirements stipulated by national laws or standards and must not exceed.

[0050] The advantage of this embodiment is to completely avoid the use of chlorine-containing d...

Abstract

The invention provides a stable hydrogen perioxide sanitizer mainly made from hydrogen perioxide, silver nitrate solution, sodium dihydrogen phosphate and disodium hydrogen phosphate. The invention also provides application of the sanitizer in drinking water sanitization. Generation of carcinogens such as trihalomethane can be decreased significantly without producing any harmful sanitation byproducts, and this sanitizer has efficient spectral sanitizing capacity.

Description

technical field [0001] The invention belongs to the field of drinking water treatment and relates to a disinfectant, in particular to a stable hydrogen peroxide disinfectant, in particular to a disinfectant suitable for disinfection and sterilization of drinking water. Background technique [0002] In recent years, disinfection and sterilization technology is one of the important means of drinking water treatment process, which has played an important role in preventing the spread of pathogenic microorganisms in water. In addition to killing pathogens in the water treatment process (ie, primary disinfection), disinfectants also need to maintain a certain amount of residue to prevent microbial re-growth in the pipe network system (ie, secondary disinfection). At present, the commonly used disinfectants in the field of drinking water mainly include chlorine disinfection (including chlorine gas and free chlorine preparations), chloramine disinfection, chlorine dioxide disinfect...
