通风方式对厨余垃圾堆肥H2S和NH3排放的影响
Effect of ventilation mode on H2S and NH3 emissions during kitchen waste composting
摘要
Abstract
In order to reduce odor substances emissions during kitchen waste composting process,experiments were designed to investigate the effects of ventilation mode on H2 S and NH3 emissions.Aerobic composting of kitchen waste and cornstalks was conducted at a ratio of 85 ∶ 15(wet weight basis)in 100-L reactors for 30 days.The gas emissions were analyzed with a force aeration at rates of 2.2 (T1,continuous ventilation),3.3 (T2,run 40 min and stop 20 min) and 6.6(T3,run 20 min and stop 30 min) m3/(m3 · h),respectively.The results showed all compost products met with national sanitation standard and reached maturity according to composting temperature.In the case of the same total air volume for three treatments,intermittent ventilation was beneficial to reduce H2S emission,but excessive ventilation increased the total sulfur loss during composting process.The NH3 emission reduced as the ventilation decreased,and ventilation mode had little effect on NH3 emission.Taking comprehensive consideration of non-hazard index,H2S and NH3 emissions,and compost quality,the ventilation mode of 3.3 m3/(m3 · h)(run 40 min and stop 20 min) was recommended to be applied to control H2S and NH3 emissions during kitchen waste composting process.关键词
