Abstract

The invention discloses a method for utilizing magnesium ions in magnesium industrial wastewater resources. The method includes the following steps: filtering the wastewater containing the magnesium ions to obtain a filtrate; using an ion exchange resin to adsorb the magnesium ions in the filtrate; eluting the ion exchange resin to obtain a magnesium-ion concentrated solution; mixing the magnesium-ion concentrated solution with industrial and agricultural by-products, fermenting by microorganisms, drying and granulating to obtain organomagnesium feed additives. According to the invention, the problems of water pollution and microelement supplement for animal bodies are also solved; the method for utilizing the magnesium ions in the magnesium industrial wastewater resources has good ecological, economic and social benefits.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a method for resource utilization of magnesium ions in magnesium industrial sewage. Background technique [0002] Water pollution has become an environmental problem that seriously endangers human health. In recent years, industrial sewage and urban domestic sewage containing heavy metals are increasing. It is extremely important to choose a reasonable method for purifying sewage. [0003] The ion exchange resin method is an important method for treating sewage containing metal elements. Active groups such as amino groups and light groups contained in the resin can perform chelation and exchange reactions with metal ions, thereby removing metal ions in sewage, and can also Used to concentrate and recover trace metals in solution, common ion exchange resins include cation exchange resins, anion exchange resins, chelating resins and humic acid resins. The ion exchange r...
