摘　　要：采用多填料复合式UAF/BAF两级工艺处理洗涤剂废水,考察了滤速对洗涤剂废水处理效果的影响。结果显示,当滤速为1. 4 m/h、BAF气水比为2∶1时,UAF对COD、表面活性剂(LAS)、TP的平均去除率分别为54%、27%、12%,BAF对COD、LAS、TP的平均去除率分别达到33. 2%、66. 4%、81. 5%,系统出水COD、LAS、TP的平均浓度分别为56、3. 1、0. 5 mg/L,达到《污水综合排放标准》(GB 8978—1996)的一级标准。UAF提高了废水的可生化性,降低了LAS的毒性,强化了BAF对难降解有机物、LAS和TP的去除效果,解决了洗涤剂废水处理难达标问题。The detergent wastewater was treated by a two-stage process of multi-filler combined UAF/BAF, and the effect of the filtration rate on the treatment efficiency was investigated. The results showed that the average removal rates of COD, LAS and TP were 54% , 27%, 12% in UAF and 33.2% , 66.4%, 81.5% in BAF, respectively, when the filtration rate of the system was 1.4 m/h and the volume ratio of air to water in BAF was 2 ： 1. The average concentrations of COD, LAS, and TP in the effluent were 56 mg/L, 3.1 mg/L, and O. 5 mg/L, respectively, which all reached the first class standard in Integrated Wastewater Discharge Standard （GB 8978 - 1996）. The results indicated that UAF improved the biodegradability of detergent industry wastewater, reduced ened the BAF＇ s removal efficiency of refractory organics, LAS and TP. effluent to satisfy the standards were solved. the toxicity of LAS, and strength-ened the BAF＇ s removal efficiency of refractory organics, LAS and TP. The problems in the treatment of effluent to satisfy the standards were solved.
