Abstract

The invention relates to a hydrophilic hollow porous microsphere resin for adsorption treatment of printing and dyeing wastewater and its preparation method and application. The preparation method of the microsphere resin comprises the following steps: (1) taking sodium p-styrenesulfonate, acrylamide, Dimethyl diallyl ammonium chloride, cross-linking agent, porogen, and catalyst are uniformly mixed to obtain an oil phase; (2) polyvinyl alcohol, gelatin, and sodium chloride are added to water and mixed uniformly to obtain an aqueous phase; ( 3) Add the oil phase to the water phase, stir, and carry out the curing reaction. After the reaction, filter and wash until the lotion is clear. Until the water droplets are not cloudy, that is. The preparation method of the invention is simple, the reaction conditions are mild, the prepared microsphere resin has high treatment efficiency and short treatment time, significantly improves the treatment effect of printing and dyeing wastewater, reduces the treatment cost of printing and dyeing wastewater, and reduces environmental pollution.

Description

technical field [0001] The invention relates to the technical field of microsphere resin materials, in particular to a hydrophilic hollow porous microsphere resin for adsorption treatment of printing and dyeing wastewater, a preparation method and application thereof. Background technique [0002] The printing and dyeing process of textiles will produce a large amount of wastewater, which contains a certain amount of dyes. The water quality of printing and dyeing wastewater is complex, with high organic content, deep color and low biodegradability. The treatment methods usually include adsorption method, flocculation method, redox method, biochemical method and membrane treatment method. The adsorption method is to use the unique physical structure or chemical structure of the adsorbent to achieve the effective removal of pollutants in the water body through the action of van der Waals force and chemical bonds. The adsorption method is used in the treatment of organic pollu...
