Abstract

The invention discloses an efficient compound disinfection and algae-killing agent which is prepared from the following components in parts by weight: 30-40 parts of 2,2-dibromo-3-nitrilopropanamide, 20-35 parts of methylisothiazolinone, 15-30 parts of methylene dithiocyanate, 6-12 parts of glutaraldehyde, 5-10 parts of quaternary ammonium salt cationic surface active agent, 3-5 parts of dispersing agent NNO, 3-5 parts of gas-phase silicon dioxide, and 200-300 parts of deionized water. All components have better coordination and cooperation properties and develop a synergistic effect, thus the efficient compound disinfection and algae-killing agent has the advantages of broad spectrum, high efficiency, durable pesticide effect, strong stripping seepage force and the like. According to the efficient compound disinfection and algae-killing agent, the defect of an existing oxidative disinfection and algae-killing agent is improved. Compared with commercially available like products in disinfection and algae-killing effect, the efficient compound disinfection and algae-killing agent has the characteristics of durability, high efficiency and stability, and has a good popularization value.

Description

technical field [0001] The invention relates to a water treatment agent, in particular to a high-efficiency composite bactericide and algicide. Background technique [0002] Bactericide algicide is a chemical that can inhibit the growth of bacteria, algae and microorganisms in water to prevent the formation of microbial slime and cause harm to the system. Take the common oxidative bactericidal algaecide as an example, the oxidative bactericidal algaecide is usually a strong oxidizing agent, such as chlorine gas, chlorazine, hypochlorite, etc. The algicide has weak penetrating ability and has no obvious effect on groups of algae and slime. It can react with organic matter in water to form harmful organic halides, and the oxidative bactericidal algicide is affected by organic matter in water and has reducing properties. The impact of the substance is greater, the duration of the drug effect is short, and it is also greatly affected by the pH value of the water. [0003] Ther...
