Problems solved by technology

However, because the processing steps of this method are cumbersome, involving steps such as heating, pH adjustment, and flocculation, it is not suitable for the treatment of large quantities of industrial wastewater; the Chinese invention patent application with application number 201610095154. This method is a method for treating aniline wastewater. In this method, various strains are symbiotic and coordinated, and they are not antagonistic to each other. When added to the wastewater treatment system, it has a good degradation effect on aniline refractory compounds.
However, the regeneration of fungi is complicated and not suitable for the treatment of large quantities of industrial wastewater

Abstract

The invention belongs to the technical field of wastewater treatment and relates to adsorbing stuffing for treating aniline-containing wastewater and a preparation method and an application thereof. In particular, the preparation comprises the following steps: 1) preparing a mixed solution of a surfactant and water as an aqueous phase; 2) preparing a mixed solution of acrylate, styrene and amino styrene as an oil phase; 3) preparing an O / W emulsion; and 4) performing free radical emulsion polymerization. The preparation method is simple and feasible. The grain size of the adsorbing stuffing prepared by the method is 200-2000[mu]m, and the adsorbing stuffing can effectively adsorb and enrich aniline in water, is easily eluted and generated and is suitable for industrial treatment of aniline-containing wastewater.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and relates to an adsorption filler for treating wastewater containing aniline, a preparation method thereof, and an application in treating wastewater containing aniline. Background technique [0002] Aniline is the most representative aromatic amine substance. It is a colorless oily liquid with aromatic odor. It is widely used in industries such as national defense, printing and dyeing, plastics, paint, pesticides and medicine. In addition, aniline is also a harmful substance that seriously pollutes the environment and endangers human health, and belongs to the three substances of "carcinogenic, teratogenic, and mutagenic". Due to the characteristics of long-term residue, bioaccumulation, and carcinogenicity, aniline is listed as 129 pollutants for priority control by the US EPA; at the same time, it is also included in the "China Environmental Priority Pollutants Blacklist" and is...
