Multifunctional water quality stabilizer

Abstract

The invention belongs to the technical field of water quality stability, and particularly relates to a multifunctional water quality stabilizer formula and a production process flow. The production process flow of the multifunctional water quality stabilizer formula comprises the steps of firstly, dissolving and uniformly stirring desalted water, phosphoric acid and inositol hexaphosphate at 40-60DEG C to obtain a mixed solution; then sequentially adding 1-hydroxyethylidene-1,1-diphosphonic acid, 2-phosphonobutane-1,2,4-tricarboxylic acid, acrylic acid-2-methyl-2-acrylamidopropanesulfonic acid copolymer, phosphonohydroxyacetic acid and sulfonic acid into the mixed solution, performing stirring for 90 minutes or more, performing mixing, finally standing for 60 minutes, filtering and sub-packaging the solution to obtain the multifunctional water quality stabilizer. According to the multifunctional water quality stabilizer disclosed by the invention, the operation can be improved by multiple times on the basis of the original concentration multiple without generating a scaling phenomenon, the water intake and the water discharge of a whole plant can be reduced to a greater extent, the environmental protection pressure faced by external water discharge is greatly reduced, and a big problem is solved for enterprises with insufficient water sources or expensive water prices and poorer supplementary water quality.

Description

technical field [0001] The invention belongs to the technical field of water quality stabilization, and in particular relates to a multifunctional water quality stabilizer. Background technique [0002] The status quo of industrial water use in my country: At present, the waste of water in the production process of industrial enterprises is serious, and the reuse rate of wastewater is about 40%, which is 1 / 2 of that in developed countries. A large amount of industrial wastewater discharged has caused great damage to the ecological environment. As a result, the production cost burden of the enterprise has also been increased, which has seriously affected the economic benefits of the enterprise. With the increasing emphasis on ecological and environmental issues in our country, the near-zero discharge of industrial wastewater is the general trend of the people and the trend of the times. At the same time, reducing costs and improving benefits is the survival of enterprises. Th...

As a result, the production cost burden of the enterprise has also been increased, which has seriously affected the economic benefits of the enterprise. With the increasing emphasis on ecological and environmental issues in our country, the near-zero discharge of industrial wastewater is the general trend of the people and the trend of the times. At the same time, reducing costs and improving benefits is the survival of enterprises. The only way to go is that the circulating cooling water system is the major water user of the factory, accounting for more than 70% of the total water consumption of the whole factory, and the amount of high-salt and low-pollution sewage generated also accounts for the vast majority of the total sewage of the enterprise; therefore , adopting near-zero discharge treatment technology for the circulating water system, and recycling and reusing the low-pollution wastewater generated by the factory, greatly reducing the amount of water intake and sewage discharged by the factory, is an effective and important measure for water saving and emission reduction. The water in the factory circulating water system deal with

[0003] At present, conventional water treatment chemicals are generally used in China for treatment; most systems can only control the concentration multiple of 2 to 4 times, so the amount of sewage discharged to the outside is relatively large; in order to meet the requirements of national policies, some systems use auxiliary concentrated sulfuric acid to adjust the pH value The method of controlling alkalinity can increase the concentration ratio to 4 to 7 times, and the amount of sewage is relatively reduced (the pond for drainage is stored for green plants, pulping, etc., and it is still difficult to digest completely), but due to a large amount of sulfate ions Newly entering the circulating water leads to aggravated corrosion of heat exchange equipment, even far exceeding the control requirements of GB50050-2017. At the same time, there is also the formation of calcium sulfate insoluble scale and sulfate ion corrosion on the cement pool wall (SO42-+CL-<2500ppm needs to be strictly controlled ) and the safe storage management of concentrated sulfuric acid; some owners also adopt the method of cation exchange and adding acid to adjust the pH value, which can achieve a concentration multiple of more than 8 times and less drainage. However, due to the higher content of chloride ions, the amount of sulfuric acid added is also more More, resulting in stronger damage to equipment and pool corrosion, and at the same time, new problems in the treatment of recycled sewage
