| 摘 要： | 采用膨胀污泥床反应器与外置管式超滤膜组成厌氧膜生物反应器(AnMBR)处理高浓度豆制品废水,实验连续运行240d,AnMBR平均处理量30～160L/d,研究了反应器的处理效果并获得了最佳水力停留时间(HRT).实验结果表明,AnMBR处理高浓度豆制品废水能够达到较好的效果,当进水COD为10g/L左右时,最佳HRT为18h,COD去除率约90%,此时相对应的有机负荷(OLR,以COD计)为13.6kg/(m3.d);稳定运行期间,单位COD气体产率为0.10～0.25L/g,甲烷含量在70%左右:在0.1MPa操作压力条件下进行膜的运行试验,考察了不同清洗方式的效果,采用最佳清洗方式膜通量可以恢复到新膜的90%左右.

| Abstract: | The efficiencies of treating high concentration soybean processing wastewater(30~160 L/d) by a side-stream anaerobic membrane bioreactor(AnMBR) were studied for over 240 days.AnMBR was comprised of a expanded granular sludge bed reactor and a side-stream ultrafiltration membrane module.The effects of hydraulic retention time(HRT) on the system performance and efficiencies of different cleaning methods on the membrane fouling were explored.The optimal HRT was about 18 h at 10 g COD/L feeding(OLR was about 13... |
