摘要: 在高含固污泥厌氧反应器中投加浓度为20 mmol·L-1（以P元素计）的磷酸盐缓冲溶液，考察不同pH值的缓冲溶液对污泥厌氧消化效果的影响。结果表明，投加pH为7.0的缓冲溶液后，总甲烷产量达到最大值61.08 L，较对照提高了38.1%，而投加pH为7.5和8.0的缓冲溶液后对产甲烷过程产生了抑制。投加缓冲溶液的各组厌氧消化至45 d，污泥的VS去除率均高于对照组。动力学研究表明，蛋白质和多糖的降解符合一级反应动力学，投加缓冲溶液有利于加速蛋白质的降解，而对多糖的降解无明显影响。

Abstract: Batch experiments were conducted to investigate the effect of phosphate buffer solution (PBS) at different initial pH levels on the anaerobic digestion of high-solid sludge. Maximum methane production (61.08 L) was achieved with the addition of PBS at the initial pH of 7.0, which was 38.1% higher than that in the control group, while the phosphate buffer solution at pH 7.5 or 8.0 inhibited the methanogenesis process. In comparison with the control group, the VS removal efficiency increased in all reactors with the addition of PBS after 45 days of digestion. The degradation of proteins and polysaccharides followed the first-order kinetics. The addition of PBS accelerated the degradation of proteins, while it had no significant impact on the degradation of polysaccharides.
