In order to treat high concentration organic amine wastewater, ZSM-5 zeolites were treated with NaOH, Na2CO3 and CH3COONa solution respectively. The samples were characterized by XRD, N2 adsorption, ICP-AES and SEM. The effects of NaOH, Na2CO3 and CH3COONa solution on the structure and physicochemical properties of ZSM-5 zeolites were investigated. The ZSM-5 zeolites were loaded with Fe before and after the treatment with different alkali solutions to oxidate and degradate the high concentration organic amine wastewater. The results showed that compared with the conventional alkali NaOH and Na2CO3, CH3COONa solution could effectively introduce mesoporous structure. Moreover, CH3COONa had less impact on the morphology and structure of ZSM-5 zeolite, and the pore formation rate and depth were easier to control. When the concentration of CH3COONa solution was 4.0 mol·L-1, the removal rate of chemical oxygen demand (CODCr) was up to 86.4%. On this basis, the uniform design method was used to further optimize the conditions for catalytic degradation of organic amine waste water, and the optimal treatment conditions were determined as follows: catalyst dosage of 40 g·L-1, reaction temperature of 95 ℃, reaction time of 150 min, initial pH of the solution of 5, amount of H2O2 of 120 mL·L-1.Under these conditions, the CODCr removal rate could reach as high as 99.6%.
