研究了石油化工污水经三级处理后回用于循环冷却水动态模拟试验中细菌数量的控制。结果表明，循环运行中污水和自来水的杀菌效果无显著差异。投加常规杀菌剂优氯净和“１２２７”即能达到对细菌控制的要求。
The control of the amount of bacteria in the dynamic simulation test of circulating cooling water after three-stage treatment of the petrochemical wastewater was studied. The results showed that there was no significant difference in the bactericidal effect of sewage and tap water in the circulating operation. Dosing conventional disinfectant chlorine net and “1227” that can achieve the requirements of bacterial control.
