| 摘 要： | 三峡库区固体有机废物厌氧发酵产生的气体有CH4、CO2、H2S、NH3、H2及多种微量气体。通过分析,三峡库区城镇每年产生垃圾约394万t,人畜禽粪尿每年约为380万吨,整个三峡库区每年填埋垃圾平均产生的甲烷气的量为2.9亿kg,人畜禽粪尿厌氧发酵产生的甲烷量为2.3亿kg,甲烷是一种比较重要的温室气体,对温室效应的贡献率仅次于二氧化碳,其他气体除了对产生区域有较大影响外,由于量小(二氧化碳除外),对整个大气环境影响相对较小。

| Abstract: | The gases generated by anaerobic fermentation of organic solid wastes in Three Gorges Reservoir Area are CH_4,CO_2,H_2S,NH_3,H_2 and some micro-gases.Data analysis shows that in the cities and towns of Three Gorges Reservoir Area,4 380 thousand tones of garbage,3 800 thousand tones of faecal were generated each year.In landfill of the garbage in average of 290 millions kg of CH_4 was generated,also in average of 230 millions kg of CH_4 was generated from the faecal.CH_4 is a very important greenhouse gas;the proportion of its contribution to greenhouse effect is next to CO_2.Other gases only have small influence on the whole atmospheric environment. |
