PURPOSE: An inorganic cohesive agents for water-treatment and a preparing method thereof are provided to improve the basicity of treated water to be proper to original water treatment of low alkalinity. CONSTITUTION: Aluminum hydroxide and hydrochloric acid are mixed in a high temperature and high pressure reactor, and the reaction and cooling of the mixture are performed. A sodium carbonate and sodium sulfate are added to the mixture. The mixture is diluted with water. The poly aluminum chloride of intermediate is generated and is stirred with mixed solution, iron chloride aqueous solution, aluminum sulfate aqueous solution, sodium hydroxide and water at a high speed. The mixture are matured at 50°C for 3 hours, and inorganic flocculant is fabricated. |
