Problems solved by technology

The reclaimed water in the reclaimed water reuse system generally contains a lot of organic matter, such as suspended solids, ammonia nitrogen, oil, organic phosphorus, etc. The water quality fluctuates in a wide range, and it is easy to breed bacteria and algae. It is difficult to continuously meet the water quality during the operation of the system. Standards, even when used as circulating cooling water or its supplementary water, the heat exchange efficiency of the system will be reduced, the corrosion will be aggravated, or the pipeline will be fouled, etc.

Embodiment Construction

[0020] The present invention will be further described below by example.

[0021] The bactericidal and algicidal composition at least includes the following two components: the first component is N-tinidazole-N-dodecyldimethyl-2-hydroxypropyl ammonium chloride; the second component is 2 - Hydroxypropyl-3-dodecyloxytrimethylammonium chloride. It can effectively prevent the growth of bacteria and algae in cooling water. At the same time, it also has the functions of slime peeling and odor removal. The results show that the composition has remarkable bactericidal and algal killing effects, and the bactericidal rate of heterotrophic bacteria, iron bacteria, ammonifying bacteria and sulfate-reducing bacteria reaches more than 95%, and the bactericidal effect is excellent. The product of the present invention has excellent bactericidal and algae killing effects on water quality with complex changes in water quality (high temperature, high index of floating objects, high index of a...

Abstract

The invention discloses a germicide and algicide composition and a preparation method of the germicide and algicide composition. By virtue of the germicide and algicide composition, the quality of recycled water in a recycled water system can be stabilized; the propagation of bacteria and algae is avoided or grown bacteria and algae are killed. The germicide and algicide composition is characterized by at least comprising the following two components: a first component, namely N-tinidazole-N-dodecyl dimethyl-2-hydroxypropyl ammonium chloride, and a second component, namely 2-hydroxypropyl-3-dodecyloxyl trimethy ammonium chloride.

Description

technical field [0001] The invention relates to industrial water treatment technologies, such as water quality treatment in reclaimed water reuse systems of power plants, steel mills, chemical plants, etc., in particular to a bactericidal and algae-killing composition and a preparation method thereof. Background technique [0002] Reclaimed water mainly refers to water that can be reused within a certain range after urban industrial sewage or domestic sewage has been treated to meet certain water quality standards, and its water quality is between upper water and lower water. The reclaimed water in the reclaimed water reuse system generally contains a lot of organic matter, such as suspended solids, ammonia nitrogen, oil, organic phosphorus, etc. The water quality fluctuates in a wide range, and it is easy to breed bacteria and algae. It is difficult to continuously meet the water quality during the operation of the system. Standards, even when used as circulating cooling wa...
