Intensive use of the benchmark simulation model No. 1 (BSM1), a protocol for objective comparison of the effectiveness of control strategies in biological nitrogen removal activated sludge plants, has also revealed a number of limitations. Preliminary definitions of the long-term benchmark simulation model No. 1 (BSM1_LT) and the benchmark simulation model No. 2 (BSM2) have been made to extend BSM1 for evaluation of process monitoring methods and plant-wide control strategies, respectively. Influent-related disturbances for BSM1_LT/BSM2 are to be generated with a model, and this paper provides a general overview of the modelling methods used. Typical influent dynamic phenomena generated with the BSM1_LT/BSM2 influent disturbance model, including diurnal, weekend, seasonal and holiday effects, as well as rainfall, are illustrated with simulation results. As a result of the work described in this paper, a proposed influent model/file has been released to the benchmark developers for evaluation purposes. Pending this evaluation, a final BSM1_LT/BSM2 influent disturbance model definition is foreseen. Preliminary simulations with dynamic influent data generated by the influent disturbance model indicate that default BSM1 activated sludge plant control strategies will need extensions for BSM1_LT/BSM2 to efficiently handle 1 year of influent dynamics.
基准模拟模型1号（BSM1）是一种用于客观比较生物脱氮活性污泥厂控制策略有效性的协议，对其的大量使用也揭示了一些局限性。已对长期基准模拟模型1号（BSM1_LT）和基准模拟模型2号（BSM2）进行了初步定义，以分别扩展BSM1用于评估过程监测方法和全厂控制策略。BSM1_LT/BSM2与进水相关的干扰将通过一个模型生成，本文提供了所使用建模方法的概述。利用BSM1_LT/BSM2进水干扰模型生成的典型进水动态现象，包括日变化、周末、季节和节假日影响以及降雨，通过模拟结果进行了说明。作为本文所述工作的成果，已向基准开发者发布了一个提议的进水模型/文件以供评估。在此次评估之前，预计将对BSM1_LT/BSM2进水干扰模型进行最终定义。利用进水干扰模型生成的动态进水数据进行的初步模拟表明，对于BSM1_LT/BSM2，默认的BSM1活性污泥厂控制策略需要扩展，以便有效处理一年的进水动态变化。
