  • The treatment effect of combination of aluminum sludge, polypropylene fiber biological packing and foxtail algae in black and odorous water was simulated. The results showed that the aluminum sludge biological packing could regulate the pH of the water system, and the foxtail algae could improve the dissolved oxygen content, so as to create the micro-environment beneficial to the microorganisms. The effluent quality of aluminum sludge biological packing was better than that of polypropylene fiber biological packing, basically reaching Class Ⅴ standard of Environmental Quality Standards for Surface Water(GB 3838-2002). Especially, the combination of aluminum sludge biological packing and foxtail algae had the best overall removal effect on water pollutants, and the effluent quality was better than that of GB 3838-2002 Class Ⅳ standard. The removal rates of CODCr, TP, TN and NH3-N were 74.62%, 93.59%, 93.19% and 96.46%, respectively.
