黑水虻生物堆肥处理鸡粪养分转化及气体排放规律研究
A study of nutrient transformation and gas emission during chicken manure biocomposting with black soldier fly
摘要
Abstract
[Objectives]The purpose of this study was to explore the effects of the addition of black soldier fly on the nutrient and maturity of materials and gas emissions changes of materials during the transformation of chicken manure,providing scientific basis for promoting the biological composting of chicken manure by the black soldier fly.[Methods]Two treatments were set up in this experiment,one treatment was fresh chicken manure added with black water fly larvae(BSF treatment)and the other treatment was without black water fly larvae(control),comparing the changes of physical and chemical properties,greenhouse gas and ammonia emissions between these two treatments.[Results]Feed insect ratio of chicken manure treated with black solider fly was 6.70,and the biotransformation rate was 38.3%,the fresh weight reduction rate of the material was 66.0%,but the fresh weight reduction rate of the control group material was only 47.6%.In the experiment with a period of 12 days,the accumulated CO2 emission of the BSF treatment group was lower than that of the control group in the first 6 days,then the accumulated CO2 emission was higher than that of the control group,but CH4 emission was far lower than that of the control group.In addition,no obvious N2O emission was observed in both BSF treatment group and control group,and the non-CO2 global warming potential of BSF treatment group was significantly lower than that of the control group,which was only 7.09%of that produced in control group.Meanwhile,its cumulative emission of ammonia was higher than that of the control group.[Conclusions]The black soldier fly could directly reduce the amount of high-moisture material chicken manure and transform it into economically valuable insect body and vermiculite sand,and its emission potential of greenhouse gas was significantly lower than that of the control group.So,biocomposting of chicken manure by the black soldier fly was a low carbon,high efficiency and high value livestock and poultry manure treatment mode.关键词
