添加过磷酸钙对蔬菜废弃物堆肥中氨气及温室气体排放的影响
Effects of superphosphate addition on NH3 and greenhouse gas emissions during vegetable waste composting
摘要
Abstract
To study the effects of superphosphate (SP) on the NH3 and greenhouse gas emissions,vegetable waste composting was performed for 27 days using 6 different treatments.In addition to the controls,five vegetable waste mixtures (0.77 m3 each) were treated with different amounts of the SP additive,namely,5％,10％,15％,20％ and 25％.The ammonia volatilization loss and greenhouse gas emissions were measured during composting.Results indicated that the SP additive significantly decreased the ammonia volatilization and greenhouse gas emissions during vegetable waste composting.The additive reduced the total NH3 emission by 4.0％ to 16.7％.The total greenhouse gas emissions (CO2-eq) of all treatments with SP additives were decreased by 10.2％ to 20.8％,as compared with the controls.The NH3 emission during vegetable waste composting had the highest contribution to the greenhouse effect caused by the four different gases.The amount of NH3 (CO2-eq) from each treatment ranged from 59.90 kg · t-1 to 81.58 kg · t-1; NH3(CO2-eq) accounted for 69％ to 77％ of the total emissions from the four gases.Therefore,SP is a cost-effective phosphorusbased fertilizer that can be used as an additive during vegetable waste composting to reduce the NH3 and greenhouse gas emissions as well as to improve the value of compost as a fertilizer.关键词
