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 ...
Embodiment 2
[0023] A resin treatment method containing m-phenylenediamine wastewater, comprising the following processing steps:
[0024] 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 5 times; wash the residual NaOH and HCl in the chromatography column with deionized water;
[0025] B. Pass the m-phenylenediamine-containing wastewater through a strong polar macroporous adsorption resin chromatography column at a flow rate of 100ml / h; collect the effluent and detect the m-phenylenediamine content, and stop passing the liquid when it exceeds the standard; wash with deionized water Re...
