METHANE,THE MOST ABUNDANT AND STABLE HYDROCARBON GAS IN THE ATMOSPHERE,PLAYS AN IMPORTANT ROLE IN THE PHOTOCHEMISTRY OF BACKGROUND TROPOSPHERE.THE GREENHOUSE EFFECT OF METHANE IS CONSIDERED TO BE 25 TIMES OF THAT OF CARBON DIOXIDE IN THE ATMOSPHERE.NITROUS OXIDE IS ONE OF THE EFFECTIVE CREENHOUSE GASES.THE CURRENT ATMOSPHERIC NITROUS OXIDE IS PAAROXIMATELY 310 PPB AND IS INCRESING AT A RATE OF 0.2-0.3%/YR.IN THIS PROJECT,WE STUDY ABOUT THE DEVEROPMENT OF THE URBAN ENVIRONMENT PRESERVATION SYSTEM ADAPTED TO THE GLOBAL ENVIRONMENT PRESERVATION.HYDROGEN FERMENTATIONS BECAME STABLE AFER 50 DAYS.AND IT DID NOT EFFECT THE DIFERENCE OF SEED SLUDGE.NITROUS OXIDE DISSOLVED IN THE EFFLUENT FROM THE FIRST REACTOR WAS EFFECTIVELY CONSUMED IN THE SECOND REACTOR (ANOXIC TANK) BY DENITRIFICATION.ADDITION OF METHANOL INTO THE FIRST REACTOR WAS AN ORGANIC CARBON SOURCE FOR DENITRIFIERS WAS EFFECTIVE TO SUPPRESS NITROUS OXIDE PRODUCTION IN THE REACTOR.ENVIRONMENTAL ADVANTAGE OF DISTRICT HEATING SYSTEM UTILIZING THE WASTE HEAT FROM SEWAGE WAS EXAMINED BY USING THE METHOD OF LIFE CYCLE ASSESSMENT.CARBONDIOXIDE EMISSION IN OPERATION STAGE IS LOWER WHEREAS THAT IN CONSTRUCTION STAGE IS HIGHER IN THE DISTINCT HEATING SYSTEMEMIT LESS CARBONDIOXIDE THAN THE CURRENT CONDITION.

甲烷是大气中最丰富、最稳定的烃类气体，在对流层背景光化学中起着重要作用。甲烷的温室效应是大气中二氧化碳的25倍。氧化亚氮是温室气体之一。目前大气中氧化亚氮的含量为310 PPB，并以0.2-0.3%/年的速度增加。YR.在这个项目中，研究了适应全球环境保护的城市环境保护系统的发展。氢发酵在50天后趋于稳定，不影响种泥的差异。第一反应器的发酵液中溶解的氧化亚氮在第二反应器中被继续消耗（缺氧罐）在第一反应器中加入甲醇作为反硝化反应器的有机碳源，抑制了反应器中N2 O的产生，用生命周期法分析了利用污水余热的区域供热系统的环境优势评估。运行阶段的二氧化碳排放量较低，而施工阶段的二氧化碳排放量较高，在不同的供热系统中，二氧化碳排放量低于当前条件。
