Abstract
The invention relates to a water treatment agent, in particular to a surface water treatment agent used for drinking water, which adopts multi-core aluminium-poly (silicon-phosphorus) aluminum chloride. The water treatment agent is prepared by taking industrial synthetic hydrochloric acid, aluminium hydroxide, calcium aluminate powder, phosphate rock powder or phosphorus pentoxide, silicon oxide and water as raw materials, and becomes liquid product after liquid residue reparation. As the molecular weight, the quantity of electric charge and the intensity of multi-core aluminium are all larger than those of poly-aluminum chloride, the coagulation property thereof is much better than that of the common poly-aluminum chloride, and the adding amount can be saved by 30 to 50 percent. The water treatment agent has good fluidity, stable performance and long-term storage. As the technology is simple and the cost performance is high, the water treatment agent can be industrially produced in larger scale.
