Abstract

The invention discloses a high-polymer functional material for adsorbing and treating organic chemical industry wastewater and a preparation method thereof. The preparation method comprises the following steps: preparing a NH4HCO3 solution, a Ca(NO3)2 solution, a (NH4)2HPO4 solution, a NaOH solution, a nitric acid solution, a urea water solution and a calcium potassium ethylenediamine tetraacetate solution into a mixed solution F; preparing a styrene chloroformic solution, a divinylbenzene chloroformic solution and an azodiisobutyronitrile chloroformic solution into a mixed solution M; dropwisely adding the mixed solution F into the mixed solution M to obtain a mixed solution O; dropwisely adding the mixed solution O into a polyvinyl alcohol solution to obtain a mixed solution P; and adding the polyvinyl alcohol solution into the mixed solution P, and centrifuging to obtain the high-polymer functional material for adsorbing and treating organic chemical industry wastewater. The manufacturing technique is simple; and the prepared high-polymer functional material has the functions of slowing release of phosphorus and adsorbing pollutants in organic chemical industry wastewater.

Description

technical field [0001] The invention belongs to the technical field of organic chemical wastewater treatment, in particular to a polymer functional material and a preparation method for adsorption treatment of organic chemical wastewater. Background technique [0002] Organic chemical wastewater involves many industries such as energy, minerals, and chemical industry. Adsorption-biodegradation, as a combined water treatment technology, plays an important role in wastewater treatment. At present, the most commonly used adsorption materials for adsorbing organic pollutants can be divided into physical adsorption materials, chemical adsorption materials and biological adsorption materials. Among them, physical adsorption materials include activated carbon, molecular sieve, zeolite, activated clay and clay ore and other solids with high specific surface area, which have the advantages of high extraction efficiency and strong enrichment function, but also have poor stability, eas...
