RO non-oxidation slime control and sterilization agent, preparation method and applications thereof

Abstract

The invention discloses an RO non-oxidation slime control and sterilization agent, which is characterized by comprising the following raw materials in percentage by mass: 10-20% of Kathon, 5-10% of bronopol, 2-5% of sodium chloride, 10-20% of potassium chloride and the balance of deionized water. The RO non-oxidation slime control and sterilization agent can be used for cleaning and sterilizing areverse osmosis system, has a good sterilization effect, can reduce the cleaning and sterilization frequency and the cleaning and sterilization time, and improve the utilization rate and the production efficiency of the reverse osmosis system, does not contain oxides and other components, does not cause oxidative damage to parts (such as part of RO membranes) in a reverse osmosis system after being used for cleaning and sterilizing the reverse osmosis system, and does not have residual oxides and other components so as to ensure high quality of water treated by the reverse osmosis system.

Description

Technical field [0001] The invention relates to the field of bactericides, in particular to a RO non-oxidized slime control and bactericide, and a preparation method and application thereof. Background technique [0002] The reverse osmosis membrane treatment system generally uses a fungicide to sterilize the incoming water in the pretreatment stage, and uses a reducing agent to reduce the residual chlorine in the water during the security filter treatment stage, because the material of the reverse osmosis membrane is very sensitive to residual chlorine. Destroy the performance of the osmotic membrane material, causing irreversible damage to the reverse osmosis membrane, thereby losing the ability to remove ions in the water. Because the reducing agent reduces all the residual chlorine in the water, there is no bactericide in the reverse osmosis membrane group, which causes the reproduction of microorganisms and bacteria, which causes microbial failure, and makes the water produc...

AI Technical Summary

Problems solved by technology

[0004] 1) After the membrane of the reverse osmosis system is contaminated by microorganisms, the pressure difference between the stages of the reverse osmosis system increases, the water yield of the reverse osmosis decreases, and the desalination rate initially remains unchanged or even increases, but with the gradual accumulation of dirt, the desalination rate begins to decline , thereby shortening the service life of the reverse osmosis membrane, leading to the early scrapping of the reverse osmosis membrane, increasing the production cost, and causing the economic loss of the enterprise

[0005] 2) After the reverse osmosis membrane is polluted by microorganisms, the produced water also contains a large number of bacteria, which affects the quality of the produced water and the quality of the main products, and will further lead to consequences such as damage to the image and reputation of the company

[0007] 1. The bactericidal effect of RO fungicide is not ideal;

[0008] 2. The RO fungicide contains oxides and other components. After it is used to clean and sterilize the reverse osmosis system, it will cause oxidative damage to the components in the reverse osmosis system (such as some RO membranes), and there will be residues, which will affect the treatment of the reverse osmosis system. water quality
