Abstract

A pilot plant has been operated in order to investigate the performance and operating characteristics of the plant concept developed for the extension of the main Vienna STP. Due to the different operational modes included in the plant concept, modelling of the carbon degradation becomes of crucial importance. A new activated sludge model is introduced which combines parts of the carbon degradation model concepts as they have been released in the ASM1-model and the ASM3-model, respectively. A method is presented which utilises results from mass balance calculations and sludge stabilisation experiments to reduce the uncertainty in the determination of the values of the simulation model parameters.

摘要

为了研究为维也纳主要污水处理厂扩建而开发的工厂概念的性能和运行特性，已运行了一个中试工厂。由于该工厂概念包含不同的运行模式，碳降解建模变得至关重要。引入了一种新的活性污泥模型，该模型结合了分别在ASM1模型和ASM3模型中发布的部分碳降解模型概念。提出了一种方法，该方法利用质量平衡计算结果和污泥稳定化实验来减少模拟模型参数值确定中的不确定性。
