Abstract

The invention discloses a circulating cooling water treatment agent which is prepared from the following substances in parts by mass: 15-30 parts of a corrosion and scale inhibitor, 1-2 parts of a dispersing agent, 15-20 parts of a sterilizing algicide, 5-10 parts of a stripping agent and 50-100 parts of water. The sterilizing algicide is composed of sodium hypochlorite and isothiazolinone, and the volume ratio of sodium hypochlorite to isothiazolinone is (0.5-1):100. The circulating water treatment agent provided by the invention can significantly adjust the pH value and reduce the corrosionrate of metals, has excellent corrosion inhibition rate and scale inhibition rate, and has the advantages that the oxidative bactericidal algicide and the non-oxidative bactericidal algicide are compounded for use, so that bacteria and algae in a circulating water system are effectively controlled, and meanwhile, the bacteria cannot generate relatively strong drug resistance.

Description

technical field [0001] The invention belongs to the technical field of circulating cooling water treatment, and in particular relates to a circulating cooling water treatment agent and a treatment method thereof. Background technique [0002] Water is a precious natural resource that human beings depend on for survival, and the shortage of water resources has become a worldwide hot topic. my country's per capita water resources are about 1 / 4 of the world's per capita share, and after ranking in the top 100, it is one of the countries with the poorest per capita water resources in the world. In industrial production, a large amount of water is needed as a cooling medium to cool products and heat exchange equipment. The supply and demand of cooling water has a major impact on the entire enterprise's industrial water use, drainage, water conservation and even society. Therefore, in order to reduce the water intake of the cooling water system, it is generally adopted to change ...
