Abstract
The invention provides a production process for a polymeric aluminum water-purifying agent. Raw materials for production of the polymeric aluminum water-purifying agent are composed of an aluminum chloride block, bauxite, hydrochloric acid and sodium hydroxide. With the production process, the quality of water purified by the polymeric aluminum water-purifying agent is superior to the quality of water purified by an aluminum sulfate flocculating agent, and water purification cost is reduced by about 25%. The polymeric aluminum water-purifying agent is applicable in a wide pH value range; the polymeric aluminum water-purifying agent has low corrosivity, good operation conditions and better dissolvability compared with aluminum sulfate.
