Problems solved by technology

Compared with chemical surfactants, biosurfactants still have great disadvantages: (1) The production methods of biosurfactants vary greatly with different microorganisms, so it is difficult to give a general ideal production guidance route; (2) Biosurfactants The low concentration and amphipathic nature of surfactants in the fermentation broth prevents their effective separation and high production costs

Embodiment 1

[0033] This example is the preparation example of degreasing preparation.

[0034] Grease-degrading bacteria agent, nutrient activator and surfactant were prepared respectively.

[0035] The oil-degrading bacteria agent is composed of three dried bacteria of Bacillus subtilis, Bacillus coagulans and Bacillus licheniformis in a weight ratio of 1:1:1, and the concentration of viable bacteria of Bacillus subtilis is (5~9)×10 8 CFU / g, the viable concentration of Bacillus coagulans is (5~9)×10 8 CFU / g, the live bacterial concentration of Bacillus licheniformis is (1~4)×10 8 CFU / g.

[0036] The nutritional activator is composed of 95% brown sugar, 5% malt infusion powder.

[0037] The surfactant is mixed by the following raw materials in parts by weight: 9 parts of sodium dodecylbenzene sulfonate, 24 parts of sodium fatty alcohol polyoxyethylene ether sulfate, 14 parts of fatty alcohol polyoxyethylene ether, coconut oil fatty acid 3 parts of diethanolamide, 3 parts of urea, 47 p...

Embodiment 2

[0040] This example is the preparation example of degreasing preparation.

[0041] Grease-degrading bacteria agent, nutrient activator and surfactant were prepared respectively.

[0042] The oil-degrading bacteria agent is composed of the dried bacteria of Bacillus subtilis and Bacillus coagulans in a weight ratio of 2:1, and the concentration of viable bacteria of Bacillus subtilis is (5-9)×10 8 CFU / g, the viable concentration of Bacillus coagulans is (5~9)×10 8 CFU / g.

[0043] Nutrient Activator consists of brown sugar.

[0044] The surfactant is mixed by the following raw materials in parts by weight: 24 parts of sodium fatty alcohol polyoxyethylene ether sulfate, 15 parts of fatty alcohol polyoxyethylene ether, 12 parts of sodium dodecylbenzenesulfonate, alkanolamide 3 parts, 46 parts of water.

[0045] The degreasing preparation is prepared according to the following method, and the parts are all parts by weight: (1) After stirring and mixing 1 part of the oil-degradi...

Embodiment 3

[0047] This example is the degradation test of the oil removal preparation prepared in Example 1 on kitchen waste grease.

[0048] Initially add 250kg of composting microbial inoculum to the aerobic composting kitchen waste disposer with a volume of 600L, and the composting microbial inoculum is prepared according to the preparation method described in the patent application number CN201410468958.3. 100kg of food waste is put into the kitchen waste every day. Among the food waste, animal offal, skin and other meat food wastes account for 50%, vegetables, potatoes and other plant food wastes account for 50%, and the oil content of food waste is 8% to 10%. %. The food waste disposer is kept ventilated and stirred and kept at a temperature above 35°C for aerobic composting. After 10 days of continuous feeding of food waste, it can be observed that the waste residue is very greasy, black muddy, and accompanied by a sour smell. Now record the grease content in the rubbish residue...

Abstract

The invention discloses an efficient aerobic composting oil removing preparation for kitchen waste. The efficient aerobic composting oil removing preparation comprises grease degradation bacteria, nutrition activators and surfactants. The grease degradation bacteria include bacillus subtilis, bacillus coagulans or / and bacillus licheniformis; the surfactants are neutral surfactants without disinfection effects. The invention further provides a method for preparing the efficient aerobic composting oil removing preparation. The method includes steps of (1), weighing the grease degradation bacteria and the nutrition activators according to a weight ratio, stirring the grease degradation bacteria, the nutrition activators and water, mixing the grease degradation bacteria, the nutrition activators and the water with one another to obtain mixed liquid and then allowing the mixed liquid to stand still at the room temperature for 2-4 hours; (2), adding the surfactants into the mixed liquid obtained at the step (1), mixing the surfactants and the mixed liquid with one another and dissolving the surfactants in the mixed liquid to obtain the efficient aerobic composting oil removing preparation. The efficient aerobic composting oil removing preparation and the method have the advantages that grease can be emulsified, the microbial grease degradation speeds can be increased, in other words, the composting efficiency of the kitchen waste can be improved, and the grease content can be reduced and reaches 5%-7% from the original 25%-28% within 48 hours.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a degreasing preparation for high-efficiency aerobic composting of kitchen garbage and a preparation method thereof. Background technique [0002] With the development of my country's economy and the acceleration of urbanization, the discharge of urban domestic waste is increasing, and the proportion of kitchen waste is increasing day by day, accounting for 37-62% of urban domestic waste. Food waste is very easy to deteriorate, rot, breed harmful microorganisms and mosquitoes, produce a large amount of toxins and emit foul-smelling gases. If it is not treated, it will seriously affect the appearance of the city, damage the health of residents, and destroy the quality of the environment. [0003] High-efficiency aerobic composting is a technology that uses microorganisms to degrade food waste. It has the advantages of low cost, fast degradation, small footprint, reductio...
