Problems solved by technology

The difference in coating and passivation methods will directly affect the production cost and performance of the product
CN1439268 discloses a kind of solid chlorine dioxide disinfectant with organic polymer as coating material, complex process, high equipment investment, also introduced organic polymers such as polyvinyl alcohol with poor biodegradability, long-term use will cause ecological environment damage destroy
CN1238130A uses the chloride of alkali metal or alkaline earth metal as passivating agent, utilizes its water absorption to reach the purpose of drying, to ensure the stability of sodium chlorite before mixing with water, but because the passivating agent used is strong in water absorption, the disinfectant Poor stability, short storage time

Abstract

The invention relates to a solid monadic chlorine dioxide disinfectant, which is characterized in that the disinfectant is configured by sodium chlorite, sodium persulfate, solid organic acid (such as a citric acid, a maleic acid or a malic acid) and a solid filling agent (such as anhydrous sodium sulfate, anhydrous zinc sulfate or anhydrous aluminium sulphate), wherein, the mass ratio of the sodium chlorite and the sodium persulfate is 100:125 to 100:140; the mass ratio of the sodium chlorite and the solid organic acid is 100:64 to 100:106; the mass ratio of the sodium chlorite and the solid filling agent is 100:158 to 100:380. The disinfectant has simple and convenient configuring technology and stability and safety of the product; therefore, the invention can be directly used for water disinfection or making chlorine dioxide disinfectant by dissolving in suitable water.

Description

technical field [0001] The invention relates to a chlorine dioxide disinfectant, in particular to a solid monobasic chlorine dioxide disinfectant and a preparation method thereof. It belongs to the technical field of environmental protection. Background technique [0002] Chlorine dioxide has multiple functions such as sterilization, anti-corrosion, fresh-keeping, and deodorization, and is internationally recognized as a fourth-generation disinfectant with excellent performance. As we all know, liquid chlorine has been used in the early water disinfection treatment, and the chloroform (carcinogen) in the treatment product is extremely harmful to the human body. In 1983, the US National Environmental Protection Agency proposed that the content of chloroform in drinking water should not exceed 0.01mg / L, and recommended chlorine dioxide as one of the most suitable technologies for controlling chloroform in water, so that it has been widely used in drinking water. Since then,...
