- 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.
