活性污泥处理系统的计算机模拟

Computer simulation of activated sludge process

介绍了以活性污泥 1号模型 (ASM1)和固体通量沉淀模型为基础 ,结合反应器原理 ,用 VB6.0计算机语言建立城市污水活性污泥模拟器的方法 ,探讨了生物反应器和二沉池的模拟工艺流程、各组分的物料平衡关系和欧拉法数值积分的步长选取等问题。模拟器的校准结果表明 ,该模拟器建立的思路和方法是可靠的 。

Based on the activated sludge model NO.1(ASM1) and Takacs secondary clarifier model, a simulator was developed with reactor principle by compiling computer programs. Simulating process and mass balance for components in the biological reactor and second settling were analyzed. The time step of Eular integration was studied. The adjusted results show that methods used in the simulator were reliable. The developed simulator can be used as a useful tool for process design and prediction.
