The design and operational parameters of an activated sludge system were analyzed treating the municipal wastewaters in Istanbul. The design methods of ATV131, Metcalf & Eddy together with model simulations were compared with actual plant operational data. The activated sludge model parameters were determined using 3-month dynamic data for the biological nutrient removal plant. The ATV131 method yielded closer sludge production, total oxygen requirement and effluent nitrogen levels to the real plant after adopting correct influent chemical oxygen demand (COD) fractionation. The enhanced biological phosphorus removal (EBPR) could not easily be predicted with ATV131 method due to low volatile fatty acids (VFA) potential.
分析了伊斯坦布尔市的城市废水处理中活性污泥系统的设计和运行参数。对 ATV131、Metcalf & Eddy 的设计方法与实际工厂运行数据进行了比较。使用生物养分去除工厂 3 个月的动态数据确定了活性污泥模型参数。经过正确采用进水化学需氧量（COD）的分段方法，ATV131 方法在污泥产量、总需氧量和出水氮水平方面更接近实际工厂。由于挥发性脂肪酸（VFA）潜力较低，ATV131 方法难以预测强化生物除磷（EBPR）。
