Bactericidal algicide, and preparation method thereof

Abstract

The invention discloses a bactericidal algicide. The bactericidal algicide comprises, by weight, 18 to 25 parts of a quaternary ammonium salt cationic surfactant, 4 to 5 parts of a natural organic polymer, 5 to 8 parts of chlorine dioxide, 1 to 2 parts of a composite organic amine, 4 to 6 parts of a dispersing agent, 8 to 12 parts of a zinc salt, and 150 to 250 parts of deionized water. The bactericidal algicide possesses scale inhibition and corrosion delaying functions; the above ingredients are harmonious; synergistic effect of the ingredients is achieved; spectrum efficiency is high; drug effect lasts long; and stripping permeability is high.

Description

technical field [0001] The invention relates to a bactericide and algaecide in the field of water treatment, in particular to a bactericide and algaecide and a preparation method thereof. Background technique [0002] Water treatment agent is a necessary chemical agent in the process of industrial water, domestic water and wastewater treatment. By using these chemicals, the water can meet certain quality requirements. During the contact process between water and air, dust, microorganisms, polluting gases (such as SO2, H2S, NH3, etc.) or insects in the air will be brought into the water system, causing water pollution, corrosion or dirt deposition and other problems. Among them, the harm caused by microorganisms is particularly serious. An important feature of microbial corrosion is that the corrosion rate is concentrated in local parts, mainly due to the acidic environment that will be produced by microbial reproduction, such as sulfate-reducing bacteria producing hydrogen ...
