Abstract

The invention discloses a production technology of high-efficiency high-concentration polymeric ferric sulfate. Under the condition that a catalytic oxidation process is omitted and massive processing equipment does not need to be increased, a rolled steel pickling byproduct namely iron oxide red reacts with industrial waste sulphuric acid, and through a negative pressure synergy concentration technology, high-efficiency high-concentration liquid polymeric ferric sulfate is prepared, so that the purposes of resource utilization is achieved, and solid products are replaced. A preparation method of the high-efficiency high-concentration polymeric ferric sulfate is simple, practical and easy to operate; and ratio of the water purifying effect of the prepared high-efficiency high-concentration liquid polymeric ferric sulfate to the water purifying effect of the solid products is close to 1 to 1, the equipment investment is low, and the production technology is suitable for industrialized production. The byproduct namely the iron oxide red and the industrial waste sulphuric acid are used, so that other problems caused in a catalytic oxidation process can be solved, and the production cost is greatly reduced. According to the production technology disclosed by the invention, waste is turned into wealth, and one kind of waste is used for governing other kinds of waste, so that environmental-friendly ideas of saving energy, reducing emission, and recycling economy can be achieved.

Description

technical field

[0001] The invention belongs to the technical field of polyferric sulfate production, and in particular relates to a production process of high-efficiency and high-concentration polyferric sulfate. Background technique

[0002] Polymerized ferric sulfate is a new type, high-quality, high-efficiency iron salt inorganic polymer flocculant, with huge molecular structure, strong adsorption capacity, and better water purification effect than all traditional inorganic water purifiers. Polymerized ferric sulfate has good coagulation performance, stable chemical properties, and fast sedimentation speed. It is applicable to a wide range of pH values ​​and is widely used in the purification of drinking water, various industrial water, industrial wastewater, and urban sewage.

[0003] At present, polyferric sulfate is mainly in two forms: liquid (total iron ≥ 11%) and solid (total iron ≥ 19%). Solid products are based on liquid products, and the liquid products are con...
