摘要:In this work, practical and measuring data collected from plant of municipal wastewater treatment that follows the activated sludge operating system, with total capacity 35,000 m3/day. The results of the steady-state simulation are discussed. Main target of this work is evaluate and optimize the plant operating system by achieving sufficient efficiency of organics degradation represented by COD removal, in additional to nitrogen removal with less consumption energy.(Activated Sludge Simulation Programme, Model No.1- ASM1) has been applied after analysis the sensitivity, calibration, verification then validation checked. Different strategies of operating system based mainly on dissolved oxygen distribution have been tested and analysed. In terms of energy conservation that associated with aeration and recirculation, strategies(1 and 4), out of seven tested strategies in additional to original one, in sequence in aeration tanks will save around 50% of energy out, and results in same COD removal as that reached by original operating strategy, represents around 94.1 %. The percentage of N removal is 98.5% compared with 73.56 % that reached by original strategy.
