摘要
Abstract
A bifunctional cleaning agent RP-78+RP-78(Z)was applied to clean the 2#circulating cooling water system of a large-scale ethylene device where a large number of biological sludges were bred.Through the analysis of water supply temperature,turbidity and water-soluble COD,the cleaning effect of the bifunctional cleaning agent was accurately evaluated.According to the experiment result,the heat exchange effect of both the water cooler and the cooling tower is restored,with the water supply temperature decreasing from 35℃to 29℃.The biological sludge with macromolecular flocs is degraded into water-soluble micromolecules.During the cleaning process,the turbidity increases from 60 NTU to 350 NTU,and the water-soluble COD rises from 60 mg/L to 978 mg/L,which breaks the limit of single exfoliation function for commonly used cleaning agents with an excellent degradation effect.The cleaning problem of the circulating cooling water system with a large amount of biological sludge is solved.关键词
