摘要
以永康市南山水厂为例,针对出厂水余氯异常波动的问题,排除在线仪表、补加氯的投加量、水质因素影响,最终查明出厂水余氯异常波动由二期2 号清水池倒流回二期1 号清水池所致,取消二期清水池出口补加氯点,并将其设置在出水汇集的总管上,出厂水余氯异常波动情况得到解决.
Abstract
Taking Nanshan Waterworks in Yongkang City as an example,in response to the abnormal fluctuation of residual chlorine in the effluent,the influence of online instruments,the amount of chlorine added,and water quality factors were excluded.Finally,it was found that the abnormal fluctuation of residual chlorine in the effluent was caused by the backflow of the phase Ⅱ No.2 clean water tank back to the phase Ⅱ No.1 clean water tank.The chlorine addition point at the outlet of the phase Ⅱ clean water tank was cancelled and set on the main pipe for water collection,and the abnormal fluctuation of residual chlorine in the effluent was solved.
