Method for biologically treating industrial circulating water and stabilizing quality thereof

Abstract

The invention discloses a method for biologically treating industrial circulating water and stabilizing the quality thereof. The method is characterized by comprising a, separately breeding bacterial strains; b, performing acclimatization for the bacterial strains; c, culturing and preparing the bacteria; d, culturing the bacteria in an industrial expanding manner to produce medicinal products; and e, directly adding the produced medicinal products into a circulating water pond. The method has the advantages that the quality of the industrial circulating cooling water is stabilized by the aid of the biotechnology and method, in a circulating water system, currently preferred chemical corrosion and scale inhibitors, bactericides and other chemical agents are replaced by microbial agents; and the microbial agents are produced by a special process, and aerobic bacteria, anaerobic bacteria and facultative anaerobic bacteria which have biological reaction functions are optimized, are subjected to acclimatization and then are cultured in an industrial expanding manner to obtain the microbial agents (medicament or microbiological products in short).

Description

technical field [0001] The invention relates to the application field of microbial treatment of circulating water, specifically a method for treating and stabilizing the quality of industrial circulating water with a biological method. Background technique [0002] In industrial production, water is used as a medium to take away heat, cool equipment and realize temperature control in the production process. This kind of water is usually called cooling water or circulating water. In order to save water and control costs, water is recycled multiple times in a relatively closed system. In order to prevent scaling of heat exchange devices, and try to increase the number of repeated uses of circulating water and increase the cycle multiple, the quality of cooling water needs to be at a good level. State and keep relatively stable, for this purpose, it is necessary to add chemicals containing phosphorus and strong acid and strong alkali, usually called corrosion and scale inhibito...

AI Technical Summary

Problems solved by technology

In order to save water and control costs, water is recycled multiple times in a relatively closed system. In order to prevent scaling of heat exchange devices, and try to increase the number of repeated uses of circulating water and increase the cycle multiple, the quality of cooling water needs to be at a good level. State and keep relatively stable, for this purpose, it is necessary to add chemicals containing phosphorus and strong acid and strong alkali, usually called corrosion and scale inhibitors, and add bactericidal and bacteriostatic agents that can kill bacteria and algae. While the cooling water quality is stable, delaying and preventing system scaling, it will also cause corrosion and damage to the equipment and pipelines of the circulating water system and cannot fundamentally prevent scaling

Therefore, regular or irregular maintenance and overhaul are required, which affects the continuity and stability of production, and even affects safe production. At the same time, fresh water needs to be replenished regularly to maintain water quality, and excess cooling water is discharged into the environment. Materials leaked into cooling water pollute the environment
