This paper presented results from anaerobic co-digestion of pulp and paper sludge (PPS) and monosodium glutamate waste liquor (MGWL). A bench-scale anaerobic digester, 10 L in volume was developed, to operate under mesophilic (37 ± 2°C) batch condition. Under versatile and reliable anaerobic conduct, high efficiency for bioconversion of PPS and MGWL were obtained in the system. The accumulative methane yield attained to 200 mL g(-1) VS(added) and the peak value of methane daily production was 0.5m(3)/(m(3)d). No inhibitions of volatile fatty acids (VFAs) and ammonia on anaerobic co-digestion were found. pH 6.0-8.0 and alkalinity 1000-4000 mg CaCO(3)/L were got without adjustment. This work showed that there was a good potential to the use of PPS and MGWL to anaerobic co-digestion for methane production.
本文介绍了纸浆和造纸污泥（PPS）与味精废液（MGWL）的厌氧共消化的结果。开发了一种 10L 的中温（37±2°C）批量厌氧消化器，在多功能且可靠的厌氧条件下，该系统实现了 PPS 和 MGWL 的高效生物转化。累积甲烷产率达到 200mL g(-1)VS（添加），每日甲烷最大产量达到 0.5m(3)/(m(3)d)。没有发现挥发性脂肪酸（VFAs）和氨对厌氧共消化的抑制作用。无需调节即可获得 pH 值 6.0-8.0 和碱度 1000-4000mg CaCO(3)/L。这项工作表明，利用 PPS 和 MGWL 进行厌氧共消化生产甲烷具有很好的潜力。
