摘要：
研究了污水回用于循环冷却水时pH、COD对细菌生长及杀菌性能的影响。结果表明，pH值在酸性范围内有利于铁细菌生长，对异养菌生长没有影响；pH值变化对优氯净的杀菌性能没有影响，而异噻唑啉酮不适于牛口峪污水回用时的杀菌。高COD有利于细菌的生长，但对杀菌剂的杀菌性能没有影响，相反与一些杀菌剂有一定的协同效应。

Abstract:
Effects of various pH and COD on bacteriagrowth and bactericidal performance while Niukouyureservoir wastewater is being reused as cooling water have been studied.The results show that pH<7 facilitatesiron bacteriagrowth,and has no effects to the growth of bacteriaand sulfate-reducingbacteria.Different pH values have no effects to dichloroisocy anuricacid so diumsaltand dode cyldimethyl benzy lammonium chloride'sbactericidal performance.Is othiazolinisn'tsuitable for bactericidal performance while Niukouyuwastewater is being reused.High COD could facilitate bacteria growth,andalso promote biocides bactericidal performance.
