A series of water purification agents having two or three components use polyferric sulfate, polyaluminum chloride and waterglass 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 is drawn. 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.
