  • The GPS-X software was applied to simulate a WWTP using cyclic activated sludge technology(CAST) process by the ASM2, and some improving measurements were provided for the chemical removal of phosphorus. The results of the parameters calibrated with the characterization of COD(SS, XS and SA) were μh=4.36 d-1，Ks=1.6 g COD/m3，kh=2.01 d-1，Kx=0.01 g COD/m3, respectively.The errors between simulated values and measured ones of WWTP effluent COD, NH+4-N and TN were less than 10%. The simulating results indicated that the added account of chemical was realtime controlled based on the TP in the influent and the flux could be reduced by about 50%.
