摘要
城市二级污水中氨氮含量较高,对含氯杀菌剂影响较大,就氨氮对含氯杀菌剂的消耗及达到同样杀菌效果所需杀菌剂进行了量化探讨,得出随着氨氮含量增加,水中残余氯含量迅速降低,需要加大加药量的结论,并提出了防治氨氮含量过高引起含氯杀菌剂药效降低的措施。
Ammonia nitrogen content in urban secondary sewage is high,which has great impact on the chlorinated fungicide.The consumption of ammonia nitrogen to chlorine fungicide and the needed fungicides to achieve the same bactericidal effect are quantified.Along with the ammonia content increase,the residual chlorine contentin the water quickly reduces,and thus more dosage is needed.It proposes measures to maintain fungicide efficiency in case of high ammonia chlorine.
