摘要：
A step-by-step design approach for sizing anoxic/oxic single-sludge activated sludge systems is presented. A computer model utilizing an EXCEL spreadsheet was also developed which simulates the pre-denitrification single-sludge activated sludge process. The biokinetic equations developed by Lawrence and McCarty are utilized in the model. The model was calibrated using data from a full-scale, pre-denitrification activated sludge process. Two-tailed, paired comparison Student's `t-test' performed on effluent BOD5, SS, TKN, NH3-N, NO3-N, and TN indicated there was no significant difference between the actual effluent concentrations and those predicted by the model at a 95 percent confidence level.
