摘要
考察了不同水井组合兑水中氨氮含量对氯耗的影响。实验结构表明:随着停留时间的延长,出水余氯质量浓度逐渐减小;当组合井水的氨氮质量浓度越高,越符合折点加氯规律。受设备条件限制,采用峰点和折点间加氯的方法,772、773,773、774这2个组合井水氨氮浓度较低,可采用普通加氯法。
The effect of ammonia nitrogen content in different water source wells on chlorine consumption was investigated.Experimental results show that:with the longer residence time of water in the water tank,the residual chlorine concentrationgradually decreased.The higher ammonia concentration combined wells is,the more in line with the break point chlorination rule is.With the way of peak point and break point point adding chlorine,the group wells of772-773,773-774has low ammonia nitorgenconcentration,conventional chlorination could be applied.
