Abstract: The aluminum sludge, a by-product of the water supply plant, was used as the filler of the constructed wetland, and A/O+ aluminum sludge filled artificial wetland combination process was adopted to treat the rural domestic sewage. The results showed that the total average removal rates of chemical oxygen demand, ammonia nitrogen, total nitrogen and total phosphorus were 82.33%, 81.58%, 76.22% and 86.50%, respectively, and the effluent quality could reach Level 1A standards of Pollutant Discharge Standard of Urban Sewage Treatment (GB 18918-2002). The removal rate of TP was 50.43% in aluminum sludge filled constructed wetland, significantly higher than that of traditional wetlands. The adsorption of aluminum sludge filler was the main way to remove phosphorus. The combination process of A/O + aluminum sludge filled constructed wetland could effectively improve the efficiency of nitrogen and phosphorus removal, realize the deep treatment of sewage, alleviate the blocking of wetlands, and extend the service life of constructed wetlands.
