This paper presents validation and implementation results of a benchmark developed for a specific full-scale oxidation ditch wastewater treatment plant. A benchmark is a standard simulation procedure that can be used as a tool in evaluating various control strategies proposed for wastewater treatment plants. It is based on model and performance criteria development. Testing of this benchmark, by comparing benchmark predictions to real measurements of the electrical energy consumptions and amounts of disposed sludge for a specific oxidation ditch WWTP, has shown that it can (reasonably) be used for evaluating the performance of this WWTP. Subsequently, the validated benchmark was then used in evaluating some basic and advanced control strategies. Some of the interesting results obtained are the following: (i) influent flow splitting ratio, between the first and the fourth aerated compartments of the ditch, has no significant effect on the TN concentrations in the effluent, and (ii) for evaluation of long-term control strategies, future benchmarks need to be able to assess settlers' performance.
本文介绍了为某特定全尺寸氧化沟污水处理厂开发的基准测试的验证和实施结果。基准测试是一种标准模拟程序，可作为评估为污水处理厂提出的各种控制策略的工具。它基于模型和性能标准的制定。通过将基准测试预测结果与某特定氧化沟污水处理厂的电能消耗和污泥处置量的实际测量值进行比较，对该基准测试进行的测试表明，它可以（合理地）用于评估该污水处理厂的性能。随后，经过验证的基准测试被用于评估一些基本和先进的控制策略。获得的一些有趣结果如下：（i）沟渠第一和第四曝气隔室之间的进水流量分配比，对出水总氮浓度没有显著影响；（ii）为了评估长期控制策略，未来的基准测试需要能够评估沉淀池的性能。
