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.
