Description of the Related Art Conventionally, algae, bacteria and other microorganisms are easily proliferated in a circulating water system such as a papermaking process at a paper pulp mill, a metal working oil circulation process, and an industrial cooling water circulation process.
It is known to cause various disorders. In particular, it is known that when slime is generated in a water system that is circulated and used, it impedes the flow in the pipe and leads to economical loss such as cooling efficiency reduction.

いにくいという欠点がある。For this reason, various compounds have been proposed and used as control agents for algae that cause slime and the like in water systems. Among such algae control agents, chlorine and the like are effective, but have corrosiveness to metals, and have the troublesome drawback of requiring continuous addition, and isothiazolone compounds are effective. However, it has a drawback that it is difficult to handle because it has strong toxicity, skin irritation and mucous membrane irritation.

った。Further, although quaternary ammonium compounds generally have the drawback of causing a lot of foaming, poly [oxyethylene (dimethyliminio) ethylene (dimethyliminio) ethylenedichloride] is substantially non-foaming and has low irritation. It is known to be sexual (Japanese Patent Publication No. 53-23)

Alternatively, its salt is also known to have a strong antibacterial property, and is also known to be effective in suppressing the growth of algae (Japanese Patent Publication No. 57-61006). However, there is a problem that even if any of these is used alone in the water system, a sufficient algae control effect cannot be obtained unless the concentration is made high.
