Problems solved by technology

However, after the circulating cooling water is used, the harmful ion components in the water increase, and a large amount of dissolved oxygen, dust and bacteria are brought in from the cooling tower, which deteriorates the water quality and brings corrosion, scaling, bacteria and algae to the cooling water system. Mud and other issues

Abstract

The invention discloses a sterilizing and algae-removing agent and an application thereof. The sterilizing and algae-removing agent consists of the following components in parts by weight: 100 parts of dodecyl dimethyl benzyl ammonium chloride, 4-6 parts of sulfamic acid, 60-80 parts of isothiazolinone, 10-20 parts of crylic acid-acrylic ester-sulfonate terpolymer, 60-80 parts of attapulgite clay, 0.2-0.4 parts of 4,4' dichloro-2-hydroxy diphenyl oxide, 4-6 parts of dodecyl ethoxy imidazolidine, 10-18 parts of sodium dichloro isocyanurate, 10-18 parts of methane dithiocyanate and 1-2 parts of epoxiconazole. The sterilizing and algae-removing agent has the advantages of efficient sterilizing and algae-removing performance, small using amount, safety, nontoxicity and environmental friendliness. The sterilizing and algae-removing agent is applied to sterilizing treatment of a circular water system.

Description

technical field [0001] The invention relates to a bactericidal algicide and its application. Background technique [0002] The development and progress of human beings are based on natural resources and the environment on which human beings live. my country is relatively rich in fresh water resources, ranking fifth in the world. But per capita resources rank eighteenth in the world. Therefore, water resources are not rich. With the growth of population and the rapid development of economy in our country, the limited water resources are even more in short supply. my country's water pollution is also very serious. From the perspective of the national situation, the current urban water shortage is serious, which has caused serious economic losses and social and environmental problems. The distribution of water-shortage cities has gradually spread to the whole country from the currently concentrated North China, Northeast China, Northwest China and the eastern coastal areas...
