Abstract

The invention belongs to the technical field of water processing, and specifically relates to a sterilization algae-extermination agent applied to circulating cooling water. The sterilization algae-extermination agent applied to circulating cooling water is composed of the following raw materials in parts by weight: trichloroisocyanuric acid, isopropanol, dehydrogenated ethoxyabietic amine, zinc oxide and kaolin. The sterilization algae-extermination agent applied to circulating cooling water has relatively strong sterilization effect and also is capable of effectively inhibiting generation of microbe and algae.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a bactericidal algicide for circulating cooling water. Background technique [0002] Circulating cooling water plays a pivotal role in the cooling system, but the circulating cooling water used contains a lot of bacteria, and some algae will grow when it is used for a long time. When it is used as a cooling medium in an industrial cooling circulating water system, it will cause deterioration of water quality, lead to blockage or pollution of heat exchangers and pipelines, and seriously affect the normal operation of production equipment. With the rapid development of social economy and technological progress, water treatment technology has been paid more and more attention. The use of water treatment chemicals can effectively kill bacteria and algae, thereby improving the cleanliness of equipment and the quality of circulating cooling water. At present, water...
