摘　　要：以沈阳市某小区城市有机垃圾(BMW)为研究对象,研究其季节特性及其在厌氧消化时产气方面的差异。结果表明,BMW总固体(TS)含量随季节变化明显,春、冬季高于夏、秋季,冬季最高,为17.55%(质量分数,下同),比夏季高3.31百分点,一年中的平均值为15.91%;挥发性固体(VS)含量随季节变化规律与TS相反,夏、秋季略高于春、冬季,夏季最高,为87.20%,春季最低,为85.08%,平均VS为86.10%,整体来看,VS随季节变化不明显。对分类后BMW进行厌氧消化,发现冬季BMW排放量少,但产气潜能却比夏季高8.5%。This study takes the organic waste from one residential area of Shenyang as the research object,aim to research their seasonal characteristics and gas production capacity during anaerobic digestion.Results showed that the total solid（TS）of bioorganic municipal waste（BMW）varied obviously with the seasons,it is higher in spring and winter than in summer and fall,the TS content achieved the highest value of 17.55%（wt%）in winter,which was 3.31points higher than that in summer,and the average TS value was 15.91%.The seasonal variation rules of VS was completely opposite with that of TS content.VS content of BMW was little higher in summer and fall than in spring and winter,the highest and lowest VS value of 87.20%and 85.08% was found in summer and spring separately,and the mean VS content of the whole year was 86.10%.Overall,the seasonal variation of VS was not as great as TS content.The BMW of different season was anaerobic digested separately,it was found that the winter BMW production was relatively low,however,its gas potential production rate was 8.5% higher than BMW of summer.
