Description
Technical Field
The invention relates to the field of bactericides, in particular to an RO non-oxidized slime control bactericide, and a preparation method and application thereof.
Background
Reverse osmosis membrane processing system generally carries out the bactericidal treatment to the influent water with germicide at the preliminary treatment stage, uses reductant reduction with the residual chlorine of aquatic at the security filter treatment stage, because the reverse osmosis membrane material is very sensitive to residual chlorine, and residual chlorine can destroy the performance of putting the infiltration membrane material, causes the irreversible damage of reverse osmosis membrane to lose the ability of desorption aquatic ion. As the reducing agent completely reduces the residual chlorine in the water, the reverse osmosis membrane group has no bactericide, so that the microorganisms and bacteria are propagated, the microorganism faults are caused, and the water yield, the pressure difference and the desalination rate of the reverse osmosis membrane are changed, thereby influencing the normal operation of production.
The reverse osmosis membrane (RO) device can remove various impurities such as inorganic salts, organic matters, colloids, microorganisms and the like in water, and has the advantages of energy conservation, no pollution, easy control and the like, and has wide application. The reverse osmosis membrane produces microbial pollution which is one of the main problems disturbing the use of the reverse osmosis membrane, the water inlet source of a reverse osmosis system is mostly surface water, particularly river water, lakes, reservoir water or tap water prepared from the water, the water quality has the characteristics of high dissolved oxygen content, rich nutrient substances such as phosphorus, nitrogen and the like, higher TOC, COD and BOD in the water, higher water temperature and the like, the water has multiple types of microorganisms and fast propagation, the reverse osmosis membrane is easily polluted by the microorganisms, and the microorganisms mainly comprise bacteria, fungi, algae and the like. After the reverse osmosis membrane is polluted by microorganisms, the reverse osmosis membrane can greatly influence the normal operation of a reverse osmosis system, and the reverse osmosis membrane is particularly expressed in the following aspects:
1) after the reverse osmosis system membrane is polluted by microorganisms, the pressure difference between sections of the reverse osmosis system is increased, the water yield of reverse osmosis is reduced, the salt rejection rate is initially unchanged or even increased, but the salt rejection rate begins to decrease along with the gradual accumulation of the dirt, so that the service life of the reverse osmosis membrane is shortened, the reverse osmosis membrane is scrapped in advance, the production cost is increased, and the economic loss of enterprises is caused.
2) After the reverse osmosis membrane is polluted by microorganisms, the produced water also contains a large amount of bacteria, the quality of the produced water is influenced, the quality of main products is influenced, and the image and the reputation of an enterprise are further damaged. Therefore, for reverse osmosis influent water containing a large amount of microorganisms, a bactericide should be added to the influent water in the pretreatment of reverse osmosis to sterilize the influent water.
However, the currently used RO fungicides have the following problems:
1. the sterilization effect of the RO bactericide is not ideal;
