摘要

The research evaluated the impact of combining adsorption and electro-peroxone processes on the post-treating effluent from a municipal landfill leachate treatment plant in a laboratory-scale baffled reactor for the first time. The performance of the proposed system for landfill leachate post-treatment was evaluated by analyzing the COD, color, turbidity, and TOC removal efficiency, as well as energy consumption, under different conditions, with the optimal parameters identified through the OFAT method. In this way, the ideal circumstances comprised an ozonation rate of 0.45 g/h, an electric current intensity of 0.7 A, cathode and anode surface areas of 30.69 cm2 each, an initial pH of 7.9, and an adsorbent dosage of 0.4 g/L. Under these specified situations, the system achieved removal efficiencies of 77.8% for COD, 100% for color, 61.2% for turbidity, and 56.8% for TOC after 60 min, representing a significant improvement compared to the alone electro-peroxone process. The present study's finding demonstrates the superiority of the combined adsorption and electro-peroxone process over the photoelectro-peroxone in the post-treatment of leachate.
