Remover for removing biological slime in recirculated cooling water and method for removing biological slime in recirculated cooling water system

Abstract

The invention discloses a remover for removing biological slime in recirculated cooling water. The remover contains a polyoxyethylene ether-type nonionic surfactant, a biosurfactant and an osmotic agent. The invention also provides a method for removing biological slime in a recirculated cooling water system by the remover. The method comprises putting the remover into the recirculated cooling water. The remover effectively removes biological slime deposited on the equipment and pipes of the recirculated cooling water system, utilizes the biodegradable environmentally-friendly biosurfactant to replace a part of synthetic surfactants, reduces a synthetic surfactant use amount, has good biological slime removal effects and reduces secondary pollution on the environment.

Description

technical field [0001] The invention relates to a biological slime stripping agent and a method for stripping slime in a circulating cooling water system, in particular to an environmentally friendly biological slime that is suitable for circulating cooling water and can effectively strip the slime in a circulating cooling water system. A mud stripping agent and a method for stripping it of slime in a circulating cooling water system. Background technique [0002] In the treatment of industrial cooling water, problems of corrosion, scaling and slime are often encountered. With the improvement of water treatment technology, most of the problems of corrosion and scale inhibition of cooling water have been better solved, but the problem of slime and bacteria and algae in the system is more prominent, especially in the case of material leakage, the slime often peels off not good. Once a large amount of microbial slime is formed, it will not only reduce the cooling effect of he...

Problems solved by technology

The disadvantage is that trihydroxymethylnitromethane will slowly decompose and release formaldehyde in slightly alkaline solution, and the service life will be shortened, so it is not suitable for slightly alkaline circulating water

[0008] In order to remove the slime in the circulating cooling water system, the existing slime stripping agent needs to use a large amount of chemically synthesized surfactants, and also causes serious pollution to the environment. With the enhancement of human environmental protection awareness, it is urgent to develop a A slime stripping agent that can effectively strip the slime in the circulating cooling water system and is environmentally friendly
