采用内循环三相流化床工艺处理含环己基甲酸废水,以自行研制的改性聚氨酯为载体,研究了各因素对环己基甲酸降解过程的影响.结果表明,进水中120 mg/L环己基甲酸对生物流化床中的微生物有明显的毒害作用,经过2周左右的驯化,毒害可基本消除.在进水COD为1 200 mg/L,反应器内溶解氧控制在3 mg/L,容积负荷<3.14 kg/(m3·d)时,出水COD可稳定达到《污水综合排放标准》(GB 8978—1996)规定的二级排放标准.
採用內循環三相流化床工藝處理含環己基甲痠廢水,以自行研製的改性聚氨酯為載體,研究瞭各因素對環己基甲痠降解過程的影響.結果錶明,進水中120 mg/L環己基甲痠對生物流化床中的微生物有明顯的毒害作用,經過2週左右的馴化,毒害可基本消除.在進水COD為1 200 mg/L,反應器內溶解氧控製在3 mg/L,容積負荷<3.14 kg/(m3·d)時,齣水COD可穩定達到《汙水綜閤排放標準》(GB 8978—1996)規定的二級排放標準.

The wastewater containing cyclohexane carboxylic acid has been treated by the three-phase biological flui-dized bed process,using the self-made and modified polyurethane as carrier.The influences of the factors on the degradation course of cyclohexane carboxylic acid are studied.The results show that 120 mg/L of cyclohexane car-boxylic acid in the influent has obvious tonic effect on the micro-organisms in the biochemical fluidized bed.The eff-ect could basically be eliminated after acclimated for about two weeks.When the influent COD is l 200 mg/L,the dissolved oxygen in the reactor controlled at 3 mg/L,and volume load<3.14 kg/(m3·d),the effluent can steadily reach the second level requirements specified in the Integrated Wastewater Discharge Standard(GB 8978—1996).
