摘要
通过对城市中水回用于火电厂循环冷却系统的微生物进行实验检测与分析,发现循环水进行前期处理后水中大肠菌群、铁细菌、硫酸盐还原菌含量分别为5个/mL、110个/mL和0.7个/mL以下,均在安全限度之内;对循环水中的异养菌检测分析发现其值在105～106范围内波动,会造成对火电厂循环水系统的危害;提出了影响火电厂循环冷却系统的主要影响菌类为异养菌的结论,对火电厂循环冷却水系统微生物的控制具有一定指导意义。
Through detecting the microorganisms in cooling water of power plant,it was found that there were 5 coliform bacteria,110 iron bacteria,0.7 sulfate-reducing bacteria in 1 mL circulating water which were within the safety limits.The heterotrophic bacteria were in the range of 105 to 106 in 1 mL cooling water.Heterotroph was the main harm bacteria in circulating cooling water.This conclusion has important guiding significance for the future power plant cooling water system to control micro-organisms.
