An innovative municipal solid waste separation technology - water separation was developed in China recently. The purpose of this study was to evaluate the feasibility of anaerobic digestion from water sorted organic fraction of municipal solid waste (WS-OFMSW) to methane. A group of bench-scale (35 L) mesophilic (30 + or - 2 degrees Celsius) batch anaerobic digestions were carried out with three total solids in reactor (TSr = 16.0%, 13.5% and 11.0%). The biodegradability of WS-OFMSW with VS/TS of 61.6% was better than that of mechanically sorted OFMSW but still poor than that of source sorted OFMSW. No inhibitions of metal ions, volatile fatty acids and ammonia on anaerobic digestion were found. The reactors with TSr 16.0%, 13.5% and 11.0% achieved methane yield of 273, 283 and 314 L/kgVS and VS removal rate of 26.1%, 35.8% and 41.8%, respectively. The average methane content in biogas was about 66% for all reactors.
最近，中国开发出一种创新的城市固体废物分离技术——水分离法。本研究旨在评估从水选有机部分城市固体废物（WS-OFMSW）中厌氧消化生产甲烷的可行性。采用三组总固体浓度（TSr）为 16.0%、13.5%和 11.0%的中温（30+或-2°C）批式（35 L）厌氧消化反应器进行了一系列实验。VS/TS 为 61.6%的 WS-OFMSW 的生物降解性优于机械分选 OFMSW，但仍逊于源头分选 OFMSW。未发现金属离子、挥发性脂肪酸和氨对厌氧消化有抑制作用。TSr 为 16.0%、13.5%和 11.0%的反应器的甲烷产量分别为 273、283 和 314 L/kgVS，VS 去除率分别为 26.1%、35.8%和 41.8%。所有反应器中沼气的平均甲烷含量约为 66%。
