摘　　要：湿垃圾三相分离固渣是厌氧消化过程产生的主要固态衍生物,黑水虻生物转化能够将其中的有机质转换成自身物质,同时产出生物蛋白,是一项环境友好型技术。为探究黑水虻生物转化过程恶臭污染释放规律,本文采用对照法设置黑水虻实验组与空白对照组,通过便携式检测仪检测各组内污染组分浓度。结果表明,氨气是生物转化过程中的主要污染成分,浓度可达48.344mg/m3,是空白对照组的2倍以上。此外,硫化氢、VOC、甲硫醇等典型污染物,浓度也明显高于空白组,研究成果对于黑水虻养殖恶臭污染高效控制具有科学指导意义。The separated solid residue is the main product from anaerobic digestion.Biotransformation of Hermetia illucens is an environmentally friendly technology,which can convert organic matter into its own substances and produce biological proteins at the same time.In this paper,the pollution characteristics of waste gas produced in the biotransformation process of Hermetia illucens fly were analyzed and studied.A control method was used to set up the experimental group and the blank control group,and the concentration of contaminated components in each group was detected by portable detector.The results showed that ammonia was the main pollution component in the biotransformation process,with a concentration of 48.344 mg/m3,more than twice that of the blank control group.In addition,the concentration of typical pollutants such as hydrogen sulfide,VOC and methyl mercaptan is also significantly higher than that of the blank group.The research results have scientific guiding significance for the efficient control of odor pollution from Hermetia illucens breeding.
