In the United Kingdom, trickling filters remain the most widespread secondary biological treatment process for municipal sewage treatment in terms of number of installations. Ongoing improvement in environmental quality of surface waters requires many of these sites to meet stringent effluent standards. Since publication of the original model for nitrification on mineral media trickling filters by Pearce and Williams in 1999 and the model for nitrification on plastic media filters by Pearce and Edwards in 2010, they have attracted widespread use. Since publication, the models have undergone some refinement and benefitted from an increased application range. Furthermore, recent publications by Pearce and Yang have delivered widely based models for predicting average and seasonal humus tank effluent suspended solids and variability at a resolution of daily 95th percentile performance. This paper presents recent developments of the nitrification models and consolidates the suite of models now available for trickling filter design, evaluation and operation.

滴滤池模型套件的开发和扩展

在英国，就安装数量而言，滴滤池仍然是城市污水处理中最普遍的二级生物处理工艺。地表水环境质量的持续改善要求许多此类场所满足严格的废水标准。自 1999 年 Pearce 和 Williams 发表矿物介质滴滤器硝化原始模型以及 2010 年 Pearce 和 Edwards 发表塑料介质过滤器硝化模型以来，它们已吸引了广泛的应用。自发布以来，这些模型经过了一些改进，并受益于应用范围的扩大。此外，Pearce 和 Yang 最近发表的出版物提供了基于广泛基础的模型，用于预测平均和季节性腐殖质池废水悬浮固体和变异性，分辨率为每日 95% 的性能。本文介绍了硝化模型的最新进展，并整合了目前可用于滴滤池设计、评估和操作的模型套件。
