摘要 再生水的水质稳定性是影响其用于居民冲厕接受程度的关键因素。研究了在不同的水温、不同的加氯量下使用次氯酸钠对不同水质的中水消毒后的水质变化趋势。结果表明,再生水的水质是影响再生水回用于冲厕水质稳定性的一个极其重要的因素,在水温较高的情况下,需要强化中水处理设施,提高再生水水质,才能在再生水回用后保证较长时间的水质稳定;在冬季室内温度条件下,水质的好坏对再生水的水质稳定性影响不大,加氯量成为了回用系统的一个关键因素;MBR出水的氨氮普遍较低,且再生水加氯量较大,为了形成保证再生水的长时间稳定,需要在再生水中加氨形成氯胺消毒;在不同的中水回用系统中,需要根据不同的再生水停留时间以及回用季节,确定回用系统出水的加氯量,保证用户终端出水达到一定的余氯值。 The reclaimed water stability is one of the key for the acceptance of household toilet flashing with reclaimed water. The variation trend of reclaimed water quality stability after sodium hypochlorite disinfection in different temperature, different amount of chlorine and different water quality were studied in this article. The results show that, in the case of high water temperature, the reclaimed water quality is a very important factor when it is used for toilet flushing. In order to guarantee the water quality stability in a long time, we should strengthen water treatment facilities to increase the reclaimed water quality. In the condition of low water temperature, the chlorine dosage is the key factor to guarantee the water stability. As ammonia nitrogen concentration in MBR effluent is low, ammonia nitrogen is needed to form chloramine to guarantee continuous sterilization ability. In different water reuse system, the amount of chlorine is determined according to the different recycled water residence time and recycle season, then it can ensure that the user terminal the residual chlorine of water reaches a certain value.
