摘  要：
利用好氧堆肥降解装置对餐厨垃圾和绿化废弃物进行处理,研究了2个进气温度(35,45℃)和3个通风速率(1.5,2.5,4 m3.h-1)6个处理组在堆肥过程中温室气体排放的变化规律.在餐厨垃圾和绿化废弃物15 d好氧堆肥过程中,堆肥第3～4天,各处理组CO2体积分数达到最高值,其中处理6的CO2体积分数在第3天达到11%,处理4在第4天达到8%;CH4的排放在第4～5天达到最高值,其中处理3和处理4的CH4体积分数在第5天分别达到14%和12%,CO2,CH4的排放变化趋势均是先升高后降低,最后趋于平缓的过程.在相同的通风速率下,大体上呈现温度越高,CO2排放体积分数越高,高浓度CH4的排放主要集中在堆肥高温前、中期.通风速率越小,CH4的排放浓度越高,通风速率越大,CH4的排放浓度越低,说明温度对CO2排放浓度影响显著,通风速率对CH4的排放浓度影响显著.

摘  要：
A degradation device of aerobic composting was used to process kitchen waste and greening waste,and the variation of the greenhouse gas emissions under the condition of inlet temperature(35,45 ℃) and ventilation rate(1.5,2.5,4 m3·h-1) in six groups were studied.During the 15 days of aerobic composting process,the emissions concentration of CO2 reached the highest value in each treatment group on 3~4 d,the concentration of CO2 reached 11% and 8% in the third group and the sixth group.The concentration of CH4 reached the highest value on 4~5 d.In the third group and the sixth group,the concentration of CH4 reached 14% and 12%,respectively.The trend of the emissions of CO2 and CH4 increased at first and then decreased,at last flattened.In the same ventilation rate,the higher temperature was,the higher the concentration of CO2.Higher the concentration of CH4 focused on the early and middle stage in high composing temperature.The lower the ventilation rate was,the higher the emission concentration of CH4.The higher the ventilation rate was,the lower the emission concentration of CH4,which mean that the temperature has significant influence on CO2 emission concentration and that ventilation rate has significant influence on CH4 emission concentration.
