摘要
采用混凝沉淀-序批式生物膜反应器(SBBR)工艺处理酱菜废水,工程运行结果表明,工艺适合低盐度酱菜废水处理,当进水COD质量浓度为800.0～1200.0 mg/L,NH4-N为20.0～40.0 mg/L,TP为4.0～7.0 mg/L时,处理后出水COD浓度为64.0 ～88.0mg/L,NH4-N浓度为2.0～4.0 mg/L,TP浓度为0.3～0.5 mg/L,达到污水综合排放标准(GB 8978-1996)一级标准.
Abstract
The combined process of "coagulation sedimentation-sequencing batch biofilm reactor (SBBR)" was used for treating the pickle wastewater.The results showed that the process was suitable for low salinity pickled wastewater.When the influent COD was 800.0-1200.0 mg/L,NH4 +-N was 20.0-40.0 mg/L and TP was 4.0-7.0 mg/L,the effluent COD was 64.0-88.0 mg/L,NH4 +-N was 2-4 mg/L,and TP was 0.3-0.5 rng/L,which could meet the first grade criteria of the national integrated wastewater discharge standard (GB8978-1996).
