新型混凝剂-聚硫氯化铝混凝性能及在电厂中的应用

Preliminary study on the coagulating performance of new-style coagulant- PACS and its application in the power plant

采用聚硫氯化铝(PACS)代替聚合氯化铝或硫酸铝,对电厂补给水系统进行混凝处理,具有很好的混凝效果,特别在处理冬季低水温、低浊度源水时,混凝效果更好。采用聚硫氯化铝混凝处理可以提高出厂水水质,保证反渗透系统的安全运行,延长反渗透使用寿命,而且节省制水成本,有利于发电厂的节能降耗,值得推广。

It is more effective of the coagulating process when replacing poly-aluminum chloride or the aluminium sulfate with poly-aluminium chloride sulfur （PACS） in the water supplying system of power plants. Especially in winter, while coagulating the low temperature and turbidity water, the coagulation effect is more better. When using poly-aluminium chloride sulfur （PACS） in coagulating process, the water quality of supplying system will be enhanced, the reverse osmosis pretreatment system （RO system） will work more safely, and the RO system will have longer working life. It will also reduce the water producing cost, and help energy saving of the electric power generation. It is worthy of generalizing among the power plants.
