摘要

研究经生化处理的牛口峪水库石化污水,回用于循环冷却水时不同浓度的Ca2+ 、Mg2+ 、Fe2- 、Cl-、SO43+对细菌生长及杀菌性能的影响。结果表明 :Ca2+ 对铁细菌生长有促进作用,对异养菌的生长没有影响 ;Mg2+ 对异养菌和铁细菌生长有促进作用,而Fe3+ 过多不利于铁细菌的生长,但对异养菌生长没有影响 ;上述三种离子对杀菌剂优氯净和 12 2 7的杀菌性能均没有影响。Cl-在 10 0~ 4 0 0mg/L,SO42 -在 10 0~ 30 0mg/L对异养菌和铁细菌生长及优氯净的杀菌效果均没有影响,而异噻唑啉酮杀菌剂则不适合用作牛口峪水库污水回用的杀菌剂。

Abstract

Effects of Ca2+, Mg2+, Fe3+, Cl-and SO42-with different concent rations on bacteria growth and bactericidal perfo rmance when Niukouyu Reservoir wastewater is reused as cooling water have been studied.The results show that Ca2+can facilitate iron bacteria growth, but has no ef fect on bacteria.Mg2+ facilitates bacteria and iron bacteria growth.More Fe3+goes against iron bacteria growth, but has no effect on bacteria grow th.All three ions have no effect on the bactericidal perfo rmance of dichloro-iso-cyanuric acid sodium salt and dodecyldimethyl benzy lammonium chloride.Cl-concent ration between 100 ~ 400 mg/L has no effect on the bactericidal performance of dichlo ro-iso-cyanuric acid sodium salt.The same result is acquired while SO42- concentration is between 100 ~ 300 mg/L.Iso thiazolin is not suitable for being used as bactericide in Niukouyu wastewater reuse.
