摘要：

研究了厌氧折流板反应器(anaerobic baffled reactor, ABR)与曝气生物滤池(biological aerated filter,BAF)的组合工艺处理大蒜切片废水的运行特点。结果表明：ABR的最佳水力停留时间（HRT）为24?h，有机负荷(COD)小于6?kg/m3·d为宜，COD的平均去除率可达87%；BAF的最佳HRT为16?h，最佳气水比为10∶1，进水有机负荷(COD)宜保持在1.1～1.4?kg/m3·d，COD的平均去除率为82.0%。ABRBAF组合工艺COD总去除率保持在98.4%～98.7%之间，出水的COD质量浓度为79～94?mg/L，出水水质满足GB89781996《污水综合排放标准》一级标准。

Abstract:

The combined process of anaerobic baffled reactor and biological aerated filter was used to deal with garlic industrial wastewater. The results showed that for ABR, the optimum HRT and organic load rate (OLR) were 24 hours and below 6?kgCOD/m3·d, respectively, and the COD removal efficiency was 87%. The optimum running condition of the BAF was at HRT 16 hours, the OLR 1.1～1.4?kgCOD/m3·d and the gas/water rate of 10∶1 with a COD removal rate of 82.0%. After being treated by the combined process of ABRBAF, the COD removal rate could reach 98.4%～98.7%, and the effluent COD ranged from 79?mg/L to 94?mg/L. Which could meet the Iclass criteria specified in the Integrated Wastewater Discharge Standard (GB89781996).
