Study on the Treatment Technology and Nutrient Transformation of Kitchen Garbage by Hermetia illucens
[Objective]To study the nutrient laws of Hermetia illucens transformation treatment of kitchen waste.[Method]Using Hermetia illu-cens and kitchen waste as research objects,Hermetia illucens were used to convert kitchen waste at normal temperature(C1,C2,C3)and high temperature constant temperature(S1,S2,S3),and the reduction rate,conversion rate,insect protein,fat and other parameters of kitchen waste were measured.[Result]Hermetia illucens significantly increases the conversion rate of kitchen waste at temperatures ranging from 30 to 33℃compared to normal temperature.S1,S2 and S3 increased the conversion rate by 9.26%,10.73%and 19.63%compared to C1,C2 and C3,respectively.The S3 group with 7.2 kg added had the highest conversion rate,and a feed to insect ratio of 2.68 to 3.20∶1 showed its ob-servable economic benefits.Hermetia illucens could convert 24.46%of low protein and 21.24%of low fat kitchen waste into high-quality feed and biodiesel raw materials with high protein and fat content of up to 43.12%and 28.58%in 21 days.58.32%-62.74%of protein and 60.14%-63.47%of fat in kitchen waste were ultimately converted into the protein and fat of the insect itself.[Conclusion]This utilization method of converting kitchen waste through Hermetia illucens will have great potential in the future.
