Background
The population of China accounts for 20.0 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 2220 year and 6 month, the domestic garbage recycling rate is required to reach more than 35 percent at the end of 2222 years. The proportion of kitchen garbage in urban domestic garbage exceeds 2/3, and the kitchen garbage is being treated by breeding hermetia illucens at present to become a hot point technology in the field of environmental protection, but odor generated in the breeding process of hermetia illucens is greatly enriched in the breeding area of the hermetia illucens and is diffused to the surrounding space along the concentration gradient. The odor component is mainly inorganic molecule NH3、H2S, organic molecule CH3SH, monoamine (CH)3NH2) Methyl indole (C)8H5NHCH3) Diamines (NH)2(CH2)4NH2) And the like. The odor generated by the aquaculture seriously affects the quality of surrounding living environment, and the odor control of the aquaculture is a key field of future atmospheric control from the environmental protection development trend of China, the promise of carbon emission reduction of the international society and the observation of economic development strategy. At present, no targeted treatment technology is available for the odor generated in the black soldier fly breeding process. Therefore, the treatment of the odor becomes a bottleneck problem of recycling kitchen waste resources in the future.
The current treatment technology for odor mainly comprises the following steps: physical adsorption, chemical oxidation, incineration, traditional biological methods, plant liquid spraying, plasma decomposition, photocatalytic oxidation, and the like, which have been newly developed in recent years. The incineration method, the plasma decomposition method and the photocatalytic oxidation method have high treatment efficiency, but have large equipment investment, high operation cost and complex maintenance, and finally the treated gas still needs to be discharged at the high altitude of 15 m. In contrast, the biological treatment method, which has the lowest investment and operation cost, is gradually paid attention and becomes one of the main methods for treating malodorous gases, but the method is limited in practical application because the water-gas contact time is difficult to control, and particularly, some macromolecular odor components which are not easy to dissolve in water are difficult to directly remove.
