Problems solved by technology

However, since the active ingredient of the solid product of polyaluminium-ferric acid is still higher than that of the liquid product, the water treatment effect of the solid product and the liquid product is about 1:3
Solid products are more cost-effective for long-distance transportation, so the market for liquid products is still not effectively promoted

Abstract

The invention discloses a production process of high-efficiency and high-concentration polyaluminum ferric chloride sulfate. The production process comprises the following steps: under a condition ofnot adding a large amount of technological equipment and other raw materials, extracting aluminum and ferric ions from ferric trihydrate alumina mineral powder by a sulfuric acid and hydrochloric aciddi-acid dissolving mode, performing polymerization reaction with calcium aluminate powder, and generating the high-efficiency and high-concentration liquid polymerized di-acid ferro-aluminum througha negative pressure synergic concentration process to replace a conventional solid product. The process is simple, practical and easy to operate; the water purification effect of the prepared high-efficiency and high-concentration liquid polymerized di-acid ferro-aluminum and the water purification effect of the conventional solid product is about 1 to 1; and the equipment investment is low, the cost performance of the raw materials is high, the production cost is greatly reduced, and the production process is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of production of polyaluminum iron bisacid, and in particular relates to a production process of high-efficiency and high-concentration polyaluminum iron bisacid. Background technique [0002] Polymerized aluminum iron bis-acid is a new type of high-efficiency water purifier, which combines the advantages of aluminum salt series and iron salt series high-efficiency water purifiers. It has high active ingredients, high basicity, high degree of polymerization, dense molecular chain network, It has the advantages of large structure, stronger adsorption and cohesion ability and better water purification effect in the process of water purification. It is an efficient, fast, low consumption, non-toxic and safe inorganic high-efficiency water purifier. [0003] At present, there are mainly two types of polyaluminum iron bisacids: liquid (total active ingredients of aluminum and iron ≥ 10.5%) and solid (total active...
