生物质资源收集过程成本、能耗及环境影响分析
收集 成本 环境
2009/11/5
基于秸秆类生物质资源的岛式分布特点，建立了描述秸秆收集过程成本、能耗和污染物排放的数学模型. 针对单资源岛秸秆收集过程，讨论了压缩对秸秆收集成本、能耗及环境的影响，建立了计算秸秆收集过程的临界收集量和临界运输距离的数学表达式，并对收集成本和能耗进行了参数敏感性分析. 结果表明，无论压缩与否，秸秆单位收集成本与a'0.5(a'为可利用资源密度)成反比，与运输距离成正比. 不压缩时收集成本与Q0.5(...

C/N对沼气产气量的影响
C/ N 沼气 产气量
2009/7/13
以鲜猪粪和风干稻草为原料, 采用批量发酵法研究不同C/ N(18/ 1 、23/ 1 、28/ 1 、33/ 1 、38/ 1 、43/ 1) 对厌氧发酵产气量和产气特性的影响。结果表明, 在常温条件下, 各处理沼气发酵均能迅速启动, 但C/ N 为23/ 1 的处理发酵启动最快;C/ N 为33/ 1 的处理60 d 发酵平均日产气量、总产气量和TS 产气率最高。
