| 摘 要： | 为实现黄连素废水的规模化处理,针对黄连素废水可生化性差、有机污染物浓度高等特点,采用UASB-MBR(升流式厌氧污泥床-膜生物反应器)组合工艺,利用微生物的生化反应去除废水中的高浓度有机物和黄连素,考察在不同HRT(水力停留时间)下CODCr和黄连素的去除效果,并采用GC-MS(气相色谱-质谱联用仪)对系统进、出水中的特征污染物进行分析. 结果表明:①在UASB与MBR的HRT分别为96、66 h,84、58 h,72、50 h,60、41 h,以及进水ρ(CODCr)和ρ(黄连素)分别为2 030.0~3 660.0和19.0~400.0 mg/L的条件下,CODCr和黄连素的平均去除率均可达到90.0%以上,出水ρ(CODCr)平均值低于150.0 mg/L,ρ(黄连素)平均值低于4.0 mg/L. ②UASB与MBR的HRT分别为72、50 h为最佳运行条件. ③UASB可以明显降低废水中特征污染物的种类和浓度,UASB出水经MBR处理后,废水中的11种主要特征污染物均得到有效降解.

| Abstract: | As a typical antibiotic pharmaceutical wastewater, berberine wastewater contains high concentrations of refractory and toxic organic pollutants. In this study, a pilot-scale upflow anaerobic sludge blanket-membrane bioreactor (UASB-MBR) system was built for the treatment of berberine wastewater. The system used biochemical reactions to remove high concentrations of organic matter and berberine. The effects of different hydraulic retention times (HRT) were observed, and GC-MS was used to analyze signature organic pollutants (SOP) in the influent and effluent. The results showed that:1) With HRT of 96,4, 72 and 60 h for the UASB reactor, and 66,8, 50 and 41 h for the MBR, and with influent CODCr and berberine concentrations of 2030.0-3660.0 and 19.0-400.0 mg/L, respectively, more than 90.0% CODCr and berberine removals were achieved. The average effluent CODCr and berberine concentrations were lower than 150.0 and 4.0 mg/L, respectively. 2) The HRTs of UASB and MBR were 72 and 50 h respectively for the best operating conditions. 3) By using GC-MS, analysis of the SOPs in the influent and effluent suggested that USAB treatment could significantly reduce the SOPs species and their relative concentrations. After MBR treatment, 11 main organic pollutants in the wastewater could be effectively degraded. |
