Embodiment 1

[0018] A resin treatment method containing m-phenylenediamine wastewater, comprising the following processing steps:

[0019] A. Measure the strong polar macroporous adsorption resin and transfer it to the chromatography column; use alcohol to flow through the chromatography column from top to bottom, wash the strong polar macroporous adsorption resin until the effluent does not produce white turbidity in water; Wash the alcohol in the strong polar macroporous adsorption resin in the chromatography column with deionized water; use 1N NaOH and 1N HCl to alternately treat the resin for 3 times; wash the residual NaOH and HCl in the chromatography column with deionized water;

[0020] B. Pass the m-phenylenediamine-containing wastewater through a strong polar macroporous adsorption resin chromatography column at a flow rate of 50ml / h; collect the effluent and detect the m-phenylenediamine content, and stop passing the liquid when it exceeds the standard; wash with deionized water ...

Abstract

The invention relates to a method for treating wastewater with metaphenylene diamine by the aid of resin, and belongs to the field of technologies for treating wastewater. The method has the advantages that the strong-polarity macroporous adsorption resin with excellent adsorption performance for the metaphenylene diamine in the wastewater is selected from similar substance attraction principles according to characteristics of high polarity and good water solubility of the metaphenylene diamine, and accordingly the metaphenylene diamine in the wastewater can be effectively removed and treatedby the aid of column chromatography.

Description

technical field [0001] The invention relates to a wastewater treatment method, more specifically, the invention relates to a resin treatment method for m-phenylenediamine-containing wastewater, which belongs to the technical field of wastewater treatment. Background technique [0002] M-phenylenediamine is an important chemical raw material in the organic chemical industry, which can be used to synthesize dyes, medicines, pesticides, rubber and plastic additives, and synthetic detergents. However, it is a highly toxic chemical with strong carcinogenic effect, and it is one of the 58 priority toxic chemicals identified in my country. In particular, the discharge of m-phenylenediamine-containing production wastewater seriously pollutes the environment and poses a great threat to the downstream drinking water sources for humans and animals, which has become an urgent problem to be solved in our country. [0003] However, because m-phenylenediamine has extremely high stability ...
