本文对新型净水剂——聚硫氯化铝和传统的硫酸铝混凝剂的净水效果进行对比研究。聚硫氯化铝在冬季低水温,高氨氮的原水情况下,不仅提高了出厂水水质,而且节省制水成本.并且简化了生产工艺的操作控制,值得推广。 In this paper, the new water purifying agent - polyaluminum chloride and conventional aluminum sulfate coagulant effect of water purification were compared. Under the conditions of low winter temperature and high ammonia nitrogen in raw water, the polyaluminum polysulfide not only improves the quality of the produced water, but also saves the cost of making the water, and simplifies the operation and control of the production process, which is worth promoting.
