Abstract

The invention provides a multifunctional non-oxidative type sterilization algicide and belongs to the technical field of water processing. The multifunctional non-oxidative type sterilization algicide is composed of, by weight, 15-30% of compound quaternary ammonium salt, 3-4% of isothiazolinone, 6-8% of penetrating agents T, 15-30% of polymaleic anhydride, 5-10% of zinc salt, 3-5% of methyl thiazolyl tetrazolium, 3-5% of composite organic amine and the balance water. The multifunctional non-oxidative type sterilization algicide integrates sterilization, algae removal, scale inhibition and corrosion inhibition functions. All components of the sterilization algicide have good intermiscibility, cooperativity and complementarity, and the sterilization algicide can replace an existing sterilization algicide with a single function. Both the formula and the preparing method of the sterilization algicide are environmentally friendly, the adopted compound raw materials do not contain phosphorus, eutrophication of water is avoided, the environment cannot be polluted by discharged water, the preparing method is simple and easy to implement, a clean process is achieved, and three industrial wastes are avoided.

Description

technical field [0001] The invention relates to a non-oxidative bactericide and algaecide, in particular to a multifunctional non-oxidative bactericide and algaecide, belonging to the technical field of water treatment. 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 and polluting gases (such as SO 2 、H 2 S, NH 3 etc.) or insects into the water system, causing water pollution, causing problems such as corrosion or dirt deposition, among which 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 ...
