沸石和过磷酸钙对鸡粪条垛堆肥甲烷排放的影响及其机制
Effects of Adding Zeolite and Superphosphate on Greenhouse Gas Emission and Methanogens During Chicken Manure Composting
摘要
Abstract
To study the effects of zeolite and superphosphate amendments on CH4 emission during the high-temperature composting, an outdoor pilot scale experiment was carried out for 46 days. The composting materials were chicken manure and rice bran, and the adding amendments were zeolite and superphosphate. The study detected CH4 emission and analyzed the structure of methanogens through PCR-DGGE and the numbers of methanogens through Quantitative Real-time PCR. The results indicated that there was more CH4 emission during the middle and late composting maturing phase, zeolite and superphosphate amendments delayed and cut CH4 emission peak. CH4 emission peak of the control treatment occurred on the 31th day of the composting (CH4, 66.08g/(m2?d)), while occurred on the 35th and 39th day in zeolite and superphosphate treatments, respectively (CH430.24 g/(m2?d) and 27.38 g/(m2?d)), and CH4 emission was reduced by 47.23% and 56.20% with zeolite and superphosphate amendments. There was no significant difference of community structure of methanogens between zeolite and superphosphate treatments, but the adding amendments of zeolite and superphosphate increased the air permeability during the late composting maturing phase, increased CO2 and CH4 emission proportion and reduced the concentration of methanogens. So, zeolite and superphosphate could reduce CH4 emission in chicken manure composting effectively, and superphosphate is better on CH4 emission reduction.关键词
