黑水虻虫卵添加量对餐厨垃圾生物转化的影响

Effect of the Addition Amount of Hermetia illucens L. Egg on Bioconversion of Food Waste

研究不同比例的虫卵添加量在黑水虻生物转化技术中对生物转化过程和鲜虫产量的影响,探索黑水虻生物转化技术对餐厨垃圾的减量化水平,以餐厨垃圾和稻壳粉为主料和辅料,每吨养殖料中分别投加80、100、120、150g虫卵。结果表明:当每吨养殖料中投加100g虫卵时,鲜虫产量最大;另外,虫卵添加量越大,黑水虻幼虫对餐厨垃圾的生物转化速率越快。说明每吨养殖料投加100g虫卵时可获得最大的经济效益;加大虫卵投加量可以缩短餐厨垃圾的处理周期,黑水虻生物转化技术对餐厨垃圾的减量化水平最高约为79%。

To study the effect of different proportion of egg addition amount on bioconversion process and output of worm, and explore the reduction level of food waste caused by bioconversion technology of H. illucens , the experiment used kitchen waste and rice husk powder as the main and supplementary materials,80,100,120 and 150 g of eggs were added to 1 ton of breeding material. The results showed that output of worm was the highest when 100 g eggs were added to 1 ton of breeding material. The larger the amount of eggs added, the faster the bioconversion rate of food waste by H. illucens . The study showed that the maximum economic benefit can be obtained when 100 g eggs were added 1 ton of breeding material, and increasing the amount of insect eggs can shorten the processing cycle of food waste, the maximum reduction level of food waste by the technology was about 79%.
