%X Being concerned on the shortages of the present 6-tank MSBR, such as the lower efficiency of phosphorus removal and sludge suspending, an upgrading 7-tank MSBR was set up through adding an anaerobic tank and adjusting the location of the concentration tank. The mathematical model and computer program based on ASM 2 were applied to simulated the 6-tank and 7-tank MSBR processes, and simulation results of two processes showed that 7-tank MSBR had higher removal efficiency for NH~+_4-N and TP than 6-tank MSBR . Then, the lab experiments for 7-tank MSBR were carried out, and removal rate of, COD, nitrogen and phosphorus were achieved at 94.2%, 81.4% and 88.7%, respectively. The upgrading process could resolve the relations appropriately among different-function tanks. And as a result, the function for the nitrogen and phosphorus removals was enhanced. The results were primarily accorded to the model, which indicated the function of activated sludge model in the development of new processes.
