Abstract

The invention provides a biological treatment process of kitchen waste. The process comprises the following steps: (1) inorganic substances in the kitchen waste which cannot be degraded are sorted, moisture is squeezed by extrusion, grinding is carried out or not, and a nourishing material is formed; (2) larvae which are carried out by biological treatment are inoculated into the nourishing material, the larvae digest the kitchen waste for 6-8 days, the kitchen waste is transformed, and the material becomes a mature material; (3) the mature material is screened, in order to obtain living larva bait and larva excreta as well as materials which are not digested; (4) the living larva is further dried and crushed, in order to obtain insect protein powder; (5) the larva excreta and the materials which are not digested are used as an organic fertilizer.

Description

A kind of technique of changing food waste biological treatment
Technical field
The invention belongs to environmental technology field, be specifically related to a kind of technique of changing food waste biological treatment.
Background technology
In existing changing food waste processing method, there are form anaerobic fermentation methane method, composting process, fermented feed method. Unareobic fermentation methagen factor of created gase is low, and organic matter transformation rate is low, has high input, and economic benefit is low. Composting process floor space is large, and easily raw miscellaneous bacteria, mosquito, easily cause foul smell secondary pollution. The product application of fermented feed method is restricted, and energy consumption is high. There is in actual applications certain defect in said method.
Biological treatment changing food waste is a kind of less investment, high efficiency, the easy method of promoting. . CN102350433A and number of patent application 2014102429308 disclose similar bioremediation, and these two kinds of methods also come with some shortcomings. What number of patent application 2014102429308 was introduced is a kind of device with changing food waste cultivation black soldier flies, poor practicability. What CN102350433A introduced is the technique that a kind of black soldier flies is processed changing food waste, and still a kind of device in essence needs to add a large amount of auxiliary materials (changing food waste: auxiliary material method amount is than being 1:(0.25 ~ 1) to increase processing cost in processing procedure.
Summary of the invention
The present invention be directed to the deficiency of existing changing food waste treatment process, a kind of simple and practical high efficiency changing food waste treatment process is provided. This technique can be the organic fertilizer of living animal bait, insect albumen powder and high-quality by changing food waste organic matter transformation, and its organic matter transformation rate is more than 92%.
Technical scheme of the present invention is a kind of technique that adopts biological method to process changing food waste, comprises the pretreatment of changing food waste, the biochemical treatment of black soldier flies, the processing of larva polypide.
Changing food waste treatment process of the present invention, comprises the following steps:
Changing food waste transports into factory, drops into feed bin, sorts out bulk inorganic material. Extrusion dehydration, after extruding, material moisture, 70% ~ 90%, is thrown material into raising dish. Spray lactic acid bacteria or saccharomycete or its combination raising dish.
Black soldier flies or fly worm's ovum are linked in raising dish, the raising material of the changing food waste of preset water content 55% ~ 65% in raising dish.
Raising dish is placed in 22 ~ 23 DEG C of temperature, carries out ovum in the environment of relative humidity 65 ~ 70%. 1-2 instar larvae after ovum, access raising dish. Per kilogram is brought up 500 ~ 1200 of material inoculations. The thickness of bringing up material is 8 ~ 15cm.
It is 27 ~ 33 DEG C that the raising dish of inoculation larva is placed in to temperature, in the environment that humidity is 55 ~ 70%, digests changing food waste with larva, can increase to bring up material or do not increase bring up material in larva raising process depending on material digestion situation.
Larva is brought up 6-8 days, brings up material and substantially digests formation taking larva excreta as main particulate material, is digestion and finishes, and now material is ripe material. All materials are moved to screen cloth and screen, isolate larva polypide or excreta and not and digestion material.
Larva polypide can be used as bait and sells, and also can dry, and is ground into insect albumen powder.
Brief description of the drawings
Figure below is the artwork of kitchen of the present invention rubbish biological processing.
Detailed description of the invention
Following examples are to further illustrate of the present invention, and claim of the present invention is protected not by embodiment is limit.
Embodiment 1:
100 kilograms of changing food wastes, sort out bulk inorganic material. Extrusion dehydration, after extruding, material weighs 55 kilograms. Throw material into raising dish, spray 100 milliliters, lactic acid bacteria or saccharomycete. By 30000 access raising dishes of 2 black soldier flies larvas in age. The thickness of bringing up material is 10cm. It is 30 DEG C that the raising dish of inoculation black soldier flies larva is placed in to temperature, rearing of larvae in the environment that humidity is 55%. Larva is brought up 6-8 days, brings up material and substantially digests formation taking larva excreta as main particulate material. All materials are moved to screen cloth and screen, isolate 13.8 kilograms of larva polypides, 11 kilograms, organic fertilizer. Larva polypide drying is pulverized and is obtained 4.31 kilograms of insect albumen powders.
Embodiment 2:
200 kilograms of changing food wastes, sort out bulk inorganic material. Extrusion dehydration, after extruding, material weighs 125 kilograms. Throw material into raising dish, spray 300 milliliters, lactic acid bacteria or saccharomycete. By 80000 access raising dishes of 2 chrysomyia megacephala larvas in age. The thickness of bringing up material is 15cm. It is 33 DEG C that the raising dish of inoculation chrysomyia megacephala larva is placed in to temperature, rearing of larvae in the environment that humidity is 65%. Chrysomyia megacephala larva is brought up 6-8 days, brings up material and substantially digests formation taking larva excreta as main particulate material. All materials are moved to screen cloth and screen, isolate 19.5 kilograms of larva polypides, 27 kilograms, organic fertilizer. Larva polypide drying is pulverized and is obtained 4.88 kilograms of insect albumen powders.
