Abstract

The invention provides a microbiological fungicide for treating circulating cooling water, belonging to the technical field of biochemical engineering. The fungicide contains pichiakudriavzevii (Pichiakudriavzevii) with the collection number of CGMCC NO.9494, Acetobacter lovaniensis (Acetobacter lovaniensis) with the collection number of CGMCC NO.9493, and lactobacillus (Lactobacillus sp.) with the collection number of CGMCC NO.9495. The invention also provides a preparation method and an application of the microbiological treatment fungicide. According to the fungicide disclosed by the invention, the concentration ratio of circulating cooling water can be improved, and the amount of supplemented water in the circulating cooling water system is reduced.

Description

technical field [0001] The invention relates to a microbial bacterial agent for treating circulating cooling water, in particular to a microbial agent based on the principles of microbial ecology, utilizing the characteristics of symbiosis, intergrowth, synergistic utilization between bacterial strains, and various metabolic types, respiratory types, and functional functions. The constructed microbial treatment bacteria agent, its preparation method and its application are used to increase the concentration ratio of circulating cooling water and reduce the supplementary water volume of the circulating cooling water system, belonging to the technical field of biochemical industry. [0002] technical background [0003] my country is a country with serious shortage of water resources, increasing revenue and reducing expenditure, scientific water use is an important measure to alleviate the restriction of my country's economic development due to the lack of water resources. Indu...
