The sewage sludge and banana peel are typical solid wastes. In this paper, sewage sludge and banana peel blends were used as raw materials for the preparation of mixed waste biological carbon. Adsorption performance of Cu 2+ and Pb 2+ at different raw material ratios were investigated. The results showed that there is no linear relationship between the adsorption performance of mixed waste biological carbon on Cu 2+ and Pb 2+ and the raw materials ratios. In this experiment, the optimized adsorption performance highest Cu 2+ and Pb 2+ removal capacity over 90% when the raw material ratios of the sewage sludge and banana peel was 4:1.
