- 摘要:
- 以UASB—SBR耦合工艺处理高浓度大蒜加工废水为目标,采用高有机负荷及接种培菌法或自然培菌法快速启动UASB和SBR反应器,考察pH、HRT、温度对高浓度大蒜加工废水中有机物去除效果及脱氮除磷性能的影响,利用高通量测序技术分析SBR污泥系统的菌群结构,并分析UASB—SBR耦合工艺对高浓度大蒜加工废水的处理效果。结果表明,通过延长HRT的方式可成功启动UASB反应器,在进水COD浓度为9 800 mg/L、温度为(35±2) ℃的条件下,UASB最佳工艺参数:HRT为45 h、pH为7.5;SBR接种培菌法具有更高的耐冲击负荷能力,有效去除有机物浓度阈值为6 000 mg/L,在进水COD浓度为6 000 mg/L的条件下,SBR最佳工艺参数:循环时间为12 h、温度为25 ℃;Bauldia和Flavobacterium为SBR活性污泥系统的优势菌属,具有较强的有机物降解能力和反硝化能力;UASB—SBR耦合工艺对COD、TP、NH3-N、TN的平均去除率分别高达99%、94.77%、95.44%、94.87%,对高浓度大蒜加工废水的处理效果显著。
- Abstract:
- UASB-SBR coupling process was applied to treat high concentration garlic processing wastewater. The UASB and SBR reactors were rapidly started by high organic load, inoculation culture or natural culture methods. The effects of pH, HRT and temperature on the removal of organic matter, nitrogen and phosphorus from high concentration garlic processing wastewater were investigated. The microbial community of sludge from SBR system was analyzed by high-throughput sequencing technology, and the performance of UASB-SBR coupling process was investigated. The UASB reactor was successfully started by extending HRT. When the COD in influent was 9 800 mg/L and the temperature was (35±2) ℃, the optimum HRT and pH of UASB were 45 h and 7.5, respectively. The inoculation culture method in SBR had higher impact load resistance, and the threshold for effective removal of organic matter concentration was 6 000 mg/L. When the COD in influent was 6 000 mg/L, the optimal cycle time and temperature of SBR were 12 h and 25 ℃, respectively. Bauldia and Flavobacterium were the dominant bacteria in SBR activated sludge system and had strong organic matter degradation and denitrification ability. The UASB-SBR coupling system had the average removal rates of COD, TP, NH3-N and TN as high as 99%, 94.77%, 95.44% and 94.87%, respectively, and it had a remarkable treatment performance of high concentration garlic processing wastewater.
