| 摘 要： | 结合N2O的产生机理,分析温度、含水率、NO2--N和底物质量浓度、pH和碱度、O2以及基质等因素对N2O释放的影响,试图探讨不同因素对N2O释放的影响规律,以期对生化过程中N2O的控制提供理论和技术支持。N2O的释放是温度、含水率、C/N、O2浓度、反应底物质量浓度、基质以及传输过程交互作用的结果。含水率、C/N、基质及温度等可通过不同途径影响溶解氧的质量浓度而影响N2O释放量;pH、NO2--N、NH3-N及温度等通过影响硝化、反硝化细菌的活性或对各阶段酶的抑制作用而影响N2O释放;土壤利用类型、植被种类、污水脱氮过程各参数等,会间接影响硝化和反硝化过程从而影响N2O的释放。

| Abstract: | Based on the mechanism of N2O production,the influence factors were analysed including temperature,moisture content,NO2--N,substrate concentration,pH,alkalinity,O2 and substrate.The influencing law of N2O was explored to provide theoretical and technical support for N2O during biochemical process.N2O emission was the results that temperature,moisture content,NO2--N,substrate concentration and substrate acted together.Moisture content,C/N,substrate and temperature could affect dissolved oxygen concentration ... |
