摘　　要：应用TUD模型对太原市杨家堡市政污水处理厂二级处理工艺升级至UCT工艺进行了模拟设计。在应用TUD模型及缺省参数对现状二级处理工艺出水进行准确模拟验证的基础上,对选定的UCT工艺建立工艺模型,应用嵌入TUD模型的AQUASIM2.0软件,以《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准为出水目标值,分别对包括最不利温度(12℃)在内的3种工况进行了模拟预测,从而确定了反应池体积、污泥回流量、耗氧量、剩余污泥量等关键性技术参数。藉此,相应确定了工艺尺寸、设备选型等其他主要工艺设计内容。The TUD model was applied to simulate the upgrading of the existing secondary treatment process of the Yangjiabu WWTP in Taiyuan. Based on the exact simulation of the effluent from existing secondary treatment process by TUD model and default parameters, the model of UCT process to be upgraded was established, and AQUASIM 2.0 inserted with the TUD model was used. Taking the class Ⅰ-A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002） as the effluent object, the simulations were carried out under three working conditions ineluding the unfavorable temperature of 12 ℃. Therefore, the key technical parameters, such as reactor volume, flow rate of return sludge, oxygen consumption, production of excess sludge were obtained, and the reactor dimension and equipment types and other design contents were determined.
