开发了一个模型程序，用于预测半间歇运行的PAC/UF系统中PAC对TOC的去除。对不同的碳剂量和反洗频率进行了模型预测。利用大规模PAC/UF试验的现场数据成功地验证了这些预测。建模过程有助于此类单元的设计。

A modeling procedure was developed to predict TOC removal by PAC in PAC/UF systems operating in a semi-batch mode. Model predictions were made for different carbon doses and backwashing frequencies. These predictions were successfully verified using field data from large-scale PAC/UF pilots. The modeling procedure can facilitate the design of such units.
