In response to the treatment issues of aniline wastewater in the pesticide industry,a direct catalytic oxidation technology based on air has been developed.A molecular sieve bimetallic catalyst was synthesized to treat aniline wastewater.The experiment determined the optimal treatment conditions as a reaction temperature of 40 °C,a reaction time of 60 minutes,a catalyst dosage of 5.0%,and an aeration rate of 6.0 L/min.Under these optimized conditions,the removal rates of aniline and chemical oxygen demand(COD)reached 95%and 92%,respectively.The study showed that reaction time and catalyst dosage have a significant impact on the treatment effect.This innovative technology provides important data support for low-cost and non-secondary polluting treatment of aniline wastewater,which plays a significant role in promoting environmental protection and resource utilization.
