The start-up procedures and characteristics of the granular sludge from a novel double circle (DC) anaerobic reactor for treating traditional Chinese medicine (TCM) wastewater were investigated. Following a start-up period, the DC reactor demonstrated good chemical oxygen demand removal at 96.87%. The Fourier transform infrared spectra and excitation-emission matrix (EEM) fluorescence spectra from the soluble microbial products of the effluent showed that amino acid and aromatic compounds in TCM wastewater were effectively removed by the DC reactor. The peak of the particle size distribution from the granular sludge in the first reaction area of the DC reactor ranged from 700 to 1500 µm with a mean size of 513 µm, and the mean size of the granular sludge in the second reaction area was approximately 250 µm. The protein-like peak in the EEM fluorescence clearly decreased and the coenzyme F420 of the fluorescence peak clearly increased for the extracellular polymeric substances of the granular sludge.
研究了一种新型双循环（DC）厌氧反应器处理中药废水时颗粒污泥的启动过程及特性。经过启动期后，DC反应器对化学需氧量的去除效果良好，去除率达96.87%。出水可溶性微生物产物的傅里叶变换红外光谱和激发-发射矩阵（EEM）荧光光谱表明，DC反应器能有效去除中药废水中的氨基酸和芳香族化合物。DC反应器第一反应区颗粒污泥的粒径分布峰值在700至1500 µm之间，平均粒径为513 µm，第二反应区颗粒污泥的平均粒径约为250 µm。颗粒污泥胞外聚合物的EEM荧光中类蛋白峰明显降低，荧光峰辅酶F420明显增加。
