摘要
虽然污水处理厂中经过二级处理后的生活污水和工业废水的水质会有很大程度的改善,但是其细菌数量还是相当庞大,并且潜藏着很多病原体。为了满足水质标准,需要对二级出水进行消毒。采用氯制剂消毒技术,其消毒的有效成分主要是有效氯。消毒剂用量要把握准确,否则一方面与微生物作用产生致癌物,另一方面消毒后的水体余氯含量太高会对微生物构成生存威胁。
Although the water quality of domestic sewage and industrial waste water will be greatly improved after the secondary treatment in wastewater treatment plant,there are still a large number of bacteria,and a lot of pathogens are hidden.In order to meet the water quality standard,we need to sterilize the secondary effluent.Using disinfection technology of chlorine preparation,the main effective component of its disinfection is available chlorine.The dosage of disinfectant should be grasped accurately,otherwise,on the one hand,it can produce carcinogens with microorganism.On the other hand,the high content of residual chlorine after disinfection will pose a threat to the survival of microbes.
