Abstract

The invention relates to a sterilizing algicide for circulating cooling water and a preparation method of the sterilizing algicide. The sterilizing algicide comprises the following components in parts by mass: 10-19 parts of chlorophenasic acid, 10-19 parts of parachlorophenol, 3-10 parts of dodecyl dimethyl benzyl ammonium chloride, 0.5-3 parts of dithiocyano-methane, 8-15 parts of sodium dodecyl benzene sulfonate, 1-5 parts of acetone oxime, 2-5 parts of methyl alcohol, 1-3 parts of diethyl ether, 4-8 parts of sodium hydroxide, and 19-37 parts of water. The sterilizing algicide has good sterilizing and algae removal effects, and has a long pesticide effect, the sterilizing rate reaches over 98%, and the pesticide effect time is more than 25 hours.

Description

technical field [0001] The invention relates to the field of water treatment agents, in particular to a bactericide and algicide for circulating cooling water and a preparation method thereof. Background technique [0002] In the circulating cooling water, there is often a large number of microbial growth and reproduction. A large number of microbial secretions make the dust, impurities and chemical sediments floating in the water stick together to form sticky deposits, which affect the normal operation of the equipment. Serious It also clogs the pipes. Chemical agents are one of the most effective and convenient ways to deal with bacteria and algae in water bodies. However, the traditional bactericide and algicide use a single bactericide, and the bactericidal effect is poor. Contents of the invention [0003] The technical problem to be solved: aiming at the shortcomings of the existing bactericidal and algicidal agents with poor bactericidal effect, the invention prov...
