氯气从氯瓶流出,经加氯机、水射器与水混溶后进入滤后水管道,再流入清水池。尽管池内停留时间保持在0.5～1.2小时,但检查出厂水余氯时,发现水泵与出水干管上所取水样的余氯值有时并不一致,有时出现加氯量大而 Chlorine flows out of the chlorine bottle and enters the filtered water pipe through the chlorinator, the water injector and the water, and then flows into the clean water tank. Although the residence time in the tank was maintained at 0.5 to 1.2 hours, when checking the residual chlorine in the produced water, it was found that the residual chlorine value of the water sample taken from the water pump and the water outlet pipe was sometimes inconsistent, sometimes causing a large amount of chlorine.
