摘　　要：表面处理行业废水水质复杂,单靠常规的生化处理很难稳定达标(COD<80 mg/L)。采用生物膜强化水解酸化/MBR工艺对综合废水进行处理,研究不同浓度重金属离子(Cu^(2+)、Ni^(2+)、Cr^(6+))冲击负荷下该工艺对COD、VFAs的去除效果,并与常规水解酸化/MBR组合工艺进行对比。结果表明,随着重金属浓度的升高,两种工艺对COD和VFAs的去除效果具有显著性差异。在30 mg/L的金属离子冲击下,生物膜强化工艺和常规工艺对COD的去除率分别为78.5%和67.2%,平均出水COD分别为64和97 mg/L,生物膜强化工艺的处理效果更好,且出水水质达到了行业排放标准。In order to control the pollution of wastewater from the surface treatment industry, the discharge of COD should be less than 80 mg/L, it is difficult to achieve this standard by conventional bio- chemical treatment. Therefore, the biofilm enhanced hydrolysis acidification/MBR process was used to treat the surface industrial comprehensive wastewater. The removal efficiency of COD and VFAs by the combined process under shock loads of different concentrations of heavy metal ions （Cu2~ , Ni2~ and Cr6＋） was investigated and compared with that by conventional hydrolysis acidification/MBR process. The results showed that with the increase of heavy metal concentration, the removal efficiency of COD and VFAs was significantly different between the two combined processes. Under the shock of metal ions at a concentration of 30 mg/L, the removal rates of COD by the combined biofilm process and the convention- al combined process were 78.5% and 67.2%, with the average effluent COD concentration of 64 mg/L and 97 mg/L, respectively. The combined biofilm process had a better treatment effect and could achieve the industrial discharge standards.
