Embodiment 1

[0025] The collected food waste is separated from solid and liquid, so that the water content of the separated food waste is 65%, and then it is broken into particles with a particle size of 2 to 50 mm. The food waste: wheat bran mass ratio is 1:0.25 Add wheat bran to the kitchen waste to form a treatment material, then add 12 million 3-6 day-old black soldier fly larvae to each ton of the treatment material, and then add EM bacteria powder to form a mixture; mix The material is loaded into the drum from the feed port 9, and the feed port 9 is closed. Turn on the exhaust fan 4 to generate an air flow inside the drum 1, and the extracted air is filtered by the air filter 5 and discharged, and every hour, the drive device 7 (motor) is turned on to drive the roller 6 to rotate, and the roller 6 is driven by friction. Drum 1 rotates slowly and evenly, and the rotation time is about 10 minutes, which can fully mix the black soldier fly larvae, auxiliary materials and kitchen waste,...

Embodiment 2

[0027] The collected kitchen waste is subjected to solid-liquid separation, so that the moisture content of the separated food waste is 85%, and then it is broken into particles with a particle diameter of 2 to 50 mm, and the food waste: (wood chips+wheat bran ) at a mass ratio of 1:1, add wood chips and wheat bran (mixed at a mass ratio of 1:1) to kitchen waste to form treatment materials, and then add 5 million 3-6-day-old black soldier flies to each ton of treatment materials Larva, then EM bacteria, forms mixture; Mixture enters in the drum type bioprocessor according to the mode of embodiment 1 and handles, and the temperature of control mixture is 32~42 ℃, and relative humidity is 35~75%, handles 24 After 1 hour, you can add an appropriate amount of mixture to increase the processing capacity. The number of additional additions should not exceed 2 times, with an interval of 24 hours. After 5 days, the treatment is completed, unloading, and then sifted to separate the blac...

Abstract

The invention discloses a process for treating restaurant-kitchen garbage by utilizing Hermitia illucens, which comprises the following steps of: carrying out solid-liquid separation on restaurant-kitchen garbage, wherein, the water content is 65-85%; crushing the restaurant-kitchen garbage into grains with the grain diameter of 2-50mm; adding auxiliary materials in the restaurant-kitchen garbageto form a treating material, wherein, the mass ratio of the restaurant-kitchen garbage to the auxiliary materials is 1: (0.25-1); adding 5,000,000-12,000,000 Hermitia illucens larvas which are 3-6 days old in per ton of processing material to form a mixture, wherein, the auxiliary materials are vegetable fiber auxiliary materials; adding the mixture into a barrel of a drum-type Hermitia illucens bioprocessor; leading the temperature of the mixture in the barrel to be 32-42 DEG C, and the relative humidity to be 35-75%; unloading after 3-5 days; sieving to separate the Hermitia illucens larvasand the treating remnants; and drying and smashing the treating remnants to be used as a feed. In the process provided by the invention, the treating period is controlled within 72 hours on the ideal condition, thus the restaurant-kitchen garbage can be transformed into a finished product of the feed, thus providing good guarantee for the continuous operations of restaurant-kitchen garbage treatment plants; and the space and resources are saved for the smaller inventory, and the potential pollution risks are avoided.

Description

Technical field: [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a process for treating kitchen waste by using black soldier flies. Background technique: [0002] According to the survey, kitchen waste accounts for a large proportion of municipal solid waste, accounting for about 35% of the total weight. At present, a large amount of kitchen waste produced by hotels, restaurants, restaurants, and canteens is basically recycled, sold and disposed of by itself. , mainly used as feed for fish, shrimp and pigs, part of which is illegally processed into hogwash oil in underground workshops and re-supplied to catering companies. The coexistence of various channels for the transportation and treatment of food waste makes government supervision ineffective and makes illegal activities organic. It can be exploited, thus laying many hidden dangers for public health and environmental pollution. [0003] Under the current ci...
