中水回用电厂循环冷却水的微生物控制研究

STUDY ON CONTROL MICROBE IN RECLAIMED WATER REUSING AS THE RECIRCULATION COOLING WATER OF A THERMAL POWER PLANT

以某电厂循环冷却系统的水质为研究对象,分别使用了3种杀菌剂,对循环冷却水系统中的大肠菌群进行了灭菌实验。实验结果表明,在确定的最佳投药量下,3种杀菌剂在数分钟至1h内即可达到99.5%以上的杀菌率,对水中的微生物具有较好的杀灭效果。实验得到一种高效廉价的复合配方药剂,经济合理,技术可行。

Three bactericides have been used to control the coliform in the recirculation cooling water in this experiment,which takes a power plant recirculation cooling water as an object.The result indicated that these three bactericides have well effect that bactericidal rate can reach above 99.5% in several minutes to 1h under the certain optimal quantity.Through the experiment one composited bactericide is got,this bactericide is high effective and inexpensive,so the technology is feasible and reasonable.
