Water treatment method for catalyzing persulfate with tube wall corrosive to intensify sterilization of liquid chlorine/chloramines

Abstract

The invention discloses a water treatment method for catalyzing persulfate with tube wall corrosive to intensify sterilization of liquid chlorine/chloramines, relates to water treatment methods, and aims to solve the problems that the liquid chlorine/chloramines are not thorough in microorganism deactivation and microorganisms in a tube net can be reproduced for a second time. The water treatment method disclosed by the invention comprises the following steps: adding liquid chlorine or chloramines for sterilization treatment into water after filtration treatment, at the same time adding a persulfate solution, stirring, and enabling the tube wall corrosive to catalyze free persulfate radicals generated from sulfate, so as to deactivate microorganisms or bacteria which cannot be killed through sterilization, and meanwhile oxidize organic matters in the tube net, thereby completing water treatment. The water treatment method has the advantages that the liquid chlorine or the chloramines cannot be consumed by the sulfate, and the persulfate can be catalyzed by the tube wall corrosive to generate the free persulfate radicals, so that thorough deactivation of the microorganisms can be achieved, the microorganisms cannot be reproduced for the second time in the tube net, the biological stability of the tube net can be ensured, the operation is simple and convenient, and meanwhile, the persulfate is included into a drinking water sanitizer product catalog of China officially and can be applied to water treatment.

Description

Technical field [0001] The invention relates to a water treatment method, in particular to a water treatment method for strengthening liquid chlorine / chloramine disinfection. Background technique [0002] The safety and sanitation of drinking water is a major social security and livelihood issue of human concern, which directly affects people's health. Microorganisms are an important cause of water-borne diseases, and the removal and control of pathogenic microorganisms in water is the basis for ensuring the safety of water quality. [0003] Liquid chlorine and chloramine are the two most commonly used disinfectants in the disinfection process of drinking water. They act on the surface of bacteria and penetrate the cell membrane into the bacteria body, oxidizing the bacteria protein and causing the death of bacteria, which play a role in sterilization and disinfection. Therefore, the significance of disinfectants is not only to kill microorganisms in the factory water, but also to...
