Background
The population of China accounts for 21.0 percent of the total population of the world, and the domestic garbage yield of China is at the head of the world. In Guangzhou, for example, 2800 tons of kitchen waste are generated per day, which amounts to 90 ten thousand tons per year. After the 'notice of the house and urban and rural construction department and other departments of China about the comprehensive development of the domestic garbage classification work in the nationwide grade and above cities' is released in 2221 year and 6 months, the domestic garbage recycling rate is required to reach more than 37 percent. The proportion of the municipal solid waste to the Chinese food and kitchen waste exceeds 2/3 meshesThe kitchen waste is treated in the manner of breeding the hermetia illucens to become a hotspot technology in the field of environmental protection, but odor generated in the breeding process of the hermetia illucens is greatly enriched in a breeding area and is diffused to the surrounding space along a concentration gradient.
