Circulating cooling water treatment agent and treatment method thereof

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. 本发明公开了一种循环冷却水处理剂，由以下质量份数的物质组成：缓蚀阻垢剂15~30份、分散剂1
