Abstract
The invention relates to treatment and utilization of fungus sticks of waste edible fungi, and in particular discloses a novel raw material for preparing active carbon. The invention also discloses a method for preparing the active carbon from the fungus sticks of the waste edible fungi, which comprises a physical method and a chemical method. The physical method comprises the following steps: carbonizing the fungus sticks of the waste edible fungi at a temperature of 450 DEG C, then introducing certain quantity of water vapor into a revolving furnace to perform high-temperature activation for 1 to 2 hours, and obtaining the active carbon after cooling, acid cleaning, water rinsing and drying; and the chemical method comprises the following steps: soaking the fungus sticks of the waste edible fungi by using phosphoric acids with different concentrations until the fungus sticks of the waste edible fungi are just wetted, then performing carbon activation for 1.5 to 2.5 hours, and obtaining the active carbon after cooling, rinsing and drying. The method has the advantages that the fungus sticks of the waste edible fungi are provided with high added value and are recycled. The method, can greatly improve the growing problem of environmental pollution on the one hand, and can increase the income per capita to certain extent on the other hand, improve the living standards of people, and also can achieve the optimized allocation of resources to a greater degree.
Description
Technical field
What the present invention relates to is a kind of method of preparing active carbon from fungus sticks of waste edible fungi, belongs to the processing of discarded edible mushroom bacterium rod and utilizes technical field.
Background technology
At present, substituting stuff cultivation is all adopted in the plantation of all kinds of edible mushroomss, and substratum is promptly polluted after using, and has only the part substratum recycling after treatment.China's edible mushrooms kind is many, plantation distributes extensively, output is big, and annual meeting produces a large amount of waste materials, particularly old producing region and scale production district.If these waste materials do not carry out appropriate processing in time, come great hidden danger will for the development of Edible Fungi, gently then cause environmental pollution, heavy then cause disease and pest to spread in a large number and endanger, cause the serious underproduction even total crop failure.If this waste material is used as biomass energy, meet the needs of construction of current China conservation-minded society and environment and Development of Economy.
Summary of the invention
What the present invention proposed is a kind of method of preparing active carbon from fungus sticks of waste edible fungi, aims to provide discarded edible mushroom bacterium rod high added value, realizes utilizing again.
Technical solution of the present invention: this method comprises physics method or chemical method, and wherein the physics method comprises following processing step:
A. discarded edible mushroom bacterium rod is crushed to 6～40 orders, removes mechanical impurity.
B. with the discarded edible mushroom bacterium rod charing in 450 ℃ of muffle furnaces that mixes, carbonization time 1～2h.
C. under steam atmosphere, be warming up under 800～950 ℃ with the heat-up rate of 5～20 ℃/min and activate, soak time is 1～2h.
D. through being cooled to be after 5% hydrochloric acid soln embathes 20min after 25 ℃, with massfraction, washing, dry gac.
450 ℃ of preferred carbonization temperatures, carbonization time 1.5 hours.
Preferred steam atmosphere, 10 ℃/min of heat-up rate, 850 ℃ of activation temperatures, soak time 1.5 hours.
Chemical method comprises following processing step:
A. discarded edible mushroom bacterium rod is crushed to 6～40 orders, removes mechanical impurity;
B. be the phosphoric acid solution dipping discarded edible mushroom bacterium rod of 35～45 ° of Be ' with concentration, solid-liquid ratio is 1: 2.4～3, make it just wetted till;
C. be warming up to 400～600 ℃ and carry out the charcoal activation in activation furnace, the charcoal soak time is 1.5～2.5h;
D. after being cooled to 25 ℃, rinsing, dry back water ratio≤10% promptly get gac.
Select for use phosphoric acid as activator, preferably phosphoric acid concentration is 38 ° of Be '.
500 ℃ of preferred activation temperatures, soak time 2h.
Advantage of the present invention: Edible Fungi is all greatly developed in various places at present, after the plantation edible mushrooms, left edible fungus stick does not also obtain development and use at present, and current edible fungus stick is being used in the agricultural fertilizer of part just, thereby and some goes out of use and causes environmental pollution.Owing to edible fungus stick is to be come by wood working mostly, therefore can utilize edible fungus stick to produce gac, this method is that the utilization of discarded edible mushroom bacterium rod opens up a new way, it makes this cheap product of edible fungus stick become a kind of new function material gac, make edible fungus stick really obtain recycling, thereby also promoted the development of edible mushrooms industry.Also further enrich simultaneously the kind of gac raw material, promoted the development of gac industry.
