Abstract: | Objective] In order to reduce the ammonium release and nitrogen loss in the process of aerobic fermentation,the aerobic fermentation experiments of municipal solid waste were carried out in the laboratory.Method] The effect of initial fermentation conditions on ammonium release was studied and the ammonium release conditions were optimized by the orthogonal test.Result] The orthogonal experiment results showed that initial C/N and condition temperature were the important factors for ammonium release.The optimized conditions was listed as follows: the moisture 60%,C/N 40:1,pH value 7.0 and condition temperature 25 ℃.Conclusion] It might provide the theoretic basis for the reducing of nitrogen losses in the process of aerobic fermentation and air pollution. |
