生物质炭对猪粪堆肥过程中氮素转化及温室气体排放的影响
Effects of biochar on nitrogen transformation and greenhouse gas emissions during swine manure composting
摘要
Abstract
Nitrogen loss and greenhouse gas emissions are the main problems resulting from the composting of livestock manure. To address this issue, a composting experiment with biochar additions of 0％(B0), 5％(B1), 10％(B2), and 15％(B3)was conducted, and ammonium and nitrate concentrations, ammonia volatilization, and greenhouse gas emissions were monitored to investigate the effects of biochar on nitro-gen loss and greenhouse gas emissions during the composting of pig manure and straw. The results showed that the addition of biochar could increase the composting temperature, and the thermophilic stage arrived 3 to 5 days in advance of that of the control. NH+4 content under the B0, B1, B2, and B3 treatments was higher by 6.6％, 41.8％, 51.9％, and 48.6％than the initial value, respectively. In addition, the ammonia volatilization was lower by 23.1％, 68.6％, and 78.4％under B1, B2, and B3 treatments than that of the control, respectively. Biochar addi-tion could decrease methane and nitrous oxide emissions by 16.3％～23.5％and 50.2％～70.7％, respectively, while CO2 emissions were sig-nificantly decreased by 20.9％under the B2 treatment from that in the control. In summary, the composting period was shortened and the ni-trogen loss and greenhouse gas emissions were reduced when applying biochar for manure composting.关键词
