摘要：
用聚合硫酸铁、聚合氯化铝和水玻璃为原料,采用两组分或三组分复配成系列净水剂,模拟郑州市自来水公司制水的工艺条件,对黄河原水进行处理试验,测定了净化后的余浊度,绘制了加药量与余浊度的关系曲线。研究发现聚合硫酸铁、聚合氯化铝和聚多硅酸以 3∶3∶2 (质量比)复配的净水剂效果最好,适用温度范围宽。研究了复合净水剂的净水机理。

Abstract:
A series of water purification agents having two or three components use polyferric sulfate, polyaluminum chloride and water-glass as raw materials.The crude water from the yellow river is treated by using the composited water purification agent, simulating the processing conditions in Zhengzhou Running Water Co.The turbidity of the remainder is determined, and the related curve of the feeding amount of the water purification agent corresponding to the turbidity of the remainder isdrawn.The results show that the effect of the composited water purification agent is the best when the mass ratio of polyferric sulfate, polyaluminium chloride and polysilicic acid is 3∶3∶2.Its suitable range of temperature is wide.The water purfication mechanism of the composited water purification agent is studied.
