摘要
N2O是大气中重要的温室气体之一,大量研究表明,污水生物处理的硝化反硝化过程是N2O的重要强源之一.通过对硝化反硝化全过程的机理分析,探讨了N2O的逸出机理.同时阐述了外界因素对N2O逸出量的影响规律.据此优化实际运行中的污水生物脱氮工艺,以达到有效控制N2O逸出的目的.
N2O is an important green house gas in the atmosphere. Research suggests that biological nitrification and denitrification of wastewater is one of the important sources of N2O. The mechanics and the affecting rules of outer factors of N2O emission are discussed here. So the actual technic of the biological denitrification of wastewater is optimized in order to control N2O emission effectively.
