Problems solved by technology

At present, the existing bactericidal algaecide has a single function, and has no ability to protect and repair the deep-seated pipeline; the reaction time is long, and the flow speed is required to be slow; the existence time after sterilization is determined, which is likely to cause multiple operations in a short period of time and increase costs

Abstract

The invention provides a germicidal and algicidal agent for sewage treatment. The germicidal and algicidal agent comprises the following raw materials: 2,2'-dihydroxy-5,5'-dichlorophenymethane, 2,2-dibromo-2-carbamoylacetonitrile, zinc dialkyl dithiophosphate, methylene bisstearamide, 3,7-dimethyl-2,6-octadienenitrile, sodium boric diglyceride monostearate, aliphatic alkyl dimethyl benzyl ammonium chloride, methylethyl ketone peroxide, 1 to 3 parts of dimethyl ethanolamine, 1,3-butylene glycol, polyvinyl alcohol and deionized water. The germicidal and algicidal agent can form a protection film on metal surface, so catalytic oxidation effect of metal is eliminated, and surface corrosion and wearing of metal are prevented; inner friction among molecular chains of a polymer is reduced; lubricity among all the raw materials is improved; reaction time is shortened; and germicidal and algicidal effect is improved.

Description

technical field [0001] The invention belongs to the field of water pollution treatment, in particular to a bactericide and algicide for sewage treatment. Background technique [0002] There are a large number of microorganisms in the cooling water. These microorganisms are generated and reproduced on the pipe wall of the cooling water equipment, which not only increases the frictional resistance of the water flow, causes the blockage of the pipe, but also seriously reduces the heat transfer efficiency of the heat exchanger. Causes dangerous pitting to perforate pipe. In order to control the production of microorganisms and the harm they cause, bactericides and algicides are generally used to kill and inhibit the growth and reproduction of microorganisms. At present, the existing bactericidal algicides have a single function, and have no ability to protect and repair the deep layers of the pipeline; the reaction time is long, and the flow speed is slow; the existence time af...
