摘　　要：柠檬酸排放废水有机污染物浓度高、颜色感观差,需对其进行深度处理。在高O3投加量(约40 mg/L),低水力停留时间(生物活性滤池和O3柱分别为25 min和10 min)条件下,生物活性滤池+O3工艺对柠檬酸废水的COD、色度和UV254的平均去除率分别为76%、93%和27%。试验出水达到城市杂用水水质标准(GB/T18920-2002),可直接回用于柠檬酸发酵过程。工艺的应用为厂家减少排污费、降低生产成本的同时,实现了废水的资源化利用。Citric acid wastewater with high strength organics and poor sense was treated by BAF＋O3 of advanced treatment. Under the conditions of great O3 dosage （about 40 mg/L） and short HRT （25 min and 10 min respectively for BAF and O3 column）, the average removal rate of COD,colority and UV254 in citric acid wastewater reached to 76%,93% and 27% respectively; the effluent reached the standard of the municipal use water （GB/T 18920-2002） and could be used directly for the fermentation process of citric acid. The application of the technological process could realize the utilization ofwastewater resource while decreasing the cost of discharging wastewater and production cost.
