摘　　要：为了准确评估在低有机负荷条件下,水厂生物活性炭池与模型试验生物活性炭滤柱对有机污染物的去除效能差别,提高模型研究成果对工程设计参数的实际参考价值,文中通过一组中试模型水厂全面模拟长江下游水源大型水厂的运行实际情况,以COD_(Mn)、DOC、UV_(254)、三维荧光为评价指标,分析水厂与模型单元在不同季节水温条件下上述有机污染物指标的出水和去除率特点,总结模型试验与水厂实际之间的结果差别。对于特定污染物指标有特定去除率要求的,在实际工程中的设计参数选择需要考虑不同季节条件下的偏差影响,并留有一定富裕量。Under the condition of low organic load, removal efficiency difference of organic pollutants between biological activated carbon(BAC) filter in the water treatment plant(WTP) and the model test biological activated carbon filter column is useful for the practical reference value of the model research results to the engineering design parameters. This paper comprehensively simulated the operation of large WTPs in the lower reaches of the Yangtze River through a group of model WTPs, taking COD_(Mn),DOC,UV_(254) and three-dimensional fluorescence as evaluation indices, and summarized the difference between the treated water and removal rate characteristics of the above organic pollutant indices of the model unit test and the actual BAC filter results of the WTP. If there were specific requirements for specific pollutant removal rate, the design parameter selection in the actual project needed to take the influence of deviation under different seasonal conditions into accounts, and a certain margin should be considered.
