Description
Technical Field
The invention relates to the technical field of fungus dreg treatment, in particular to a method for recycling antibiotic fungus dreg and application thereof.
Background
The antibiotic fungus dreg (simply referred to as fungus dreg) is one of main wastes discharged by pharmaceutical enterprises such as antibiotics and the like, belongs to dangerous waste, and most of components in the fungus dreg are water, and the solid mainly comprises hypha, residue, residual raw materials, salts, metabolites, residual antibiotics and the like, and has the characteristics of high yield, easy spoilage, difficult treatment and the like; meanwhile, the dry solids of the fungus residues contain protein, cellulose, grease and the like, and have higher nutrient substances. In order to bring the economic benefit of the fungus dreg into play, the fungus dreg can be recycled by means of fertilizer, feed, fuel, raw material and the like.
The technical route of fungus dreg fertilizer mainly comprises slurry spraying granulation and composting, wherein the slurry spraying granulation needs to add water and heat and condition fungus dreg, and adopts high-temperature wind as a heat source, so that the defects of large exhaust emission, large environmental hazard, high production energy consumption and the like exist; the composting needs to be further fermented after reasonably storing the fungus residues, and has the defects of large occupied area, low turnover speed, easy generation of malodorous gas, inflammability, explosiveness, complex subsequent treatment process, incapability of eliminating certain antibiotics and the like. The common antibiotic residues are used as feed for the breeding industry, however, due to safety factors, the technical route of large-scale feed of the common antibiotic residues cannot be implemented, and the common antibiotic residues are generally only used as carriers of veterinary drugs and cannot be used as common feed. As the fungus dreg has a large amount of organic matters, the fungus dreg can be used for fuel, however, the fungus dreg is easy to generate nitrogen oxides and other problems in the combustion process, the subsequent treatment difficulty is high, the added value is low, and the economic benefit is poor. In addition, the extraction of the fungus residues or the extraction after fermentation is expected to produce useful raw materials such as humic acid, enzyme preparations, fungus agents and the like, but the raw material utilization mode has the problems of limited demand of subsequent products, small production scale, incapability of processing a large amount of fungus residues and the like.
At present, most of treatment processes for recycling bacterial residues have the problems of difficult dehydration, high yield, high treatment difficulty, generation of a large amount of peculiar smell gas, serious pollution of the treatment process, residual antibiotics after treatment and the like, so that the recycling of the bacterial residues has a large limitation. Therefore, it is necessary to develop a method for recycling the bacterial residues, which is easy to process, does not cause pollution, has large processing capacity and has no antibiotic residues after the processing.
Disclosure of Invention
The invention aims to provide a method for recycling antibiotic fungus dreg and application thereof, and the method has the advantages of low production cost, large treatment capacity, simple and convenient treatment process, environmental friendliness and the like.
The invention provides a method for recycling antibiotic fungus residues, which comprises the following steps:
a) Tabletting the antibiotic wet fungus residues to obtain fungus residue tablets;
b) Spreading the fungus dreg pieces on a metal plate, and heating the metal plate by using a heat source to dry the fungus dreg pieces to obtain dry fungus dreg;
c) And (3) crushing and granulating the dry fungus residues to obtain fungus residue particles.
The invention does not limit the source of the antibiotic wet fungus dreg strictly, and can be various antibiotic fungus dreg discharged by various antibiotic pharmaceutical enterprises; the antibiotic fungus dreg recycling treatment method has universality and can be used for various different antibiotic fungus dreg, such as amoxicillin fungus dreg, cephalosporin fungus dreg and the like.
The antibiotic wet bacterial dreg has great amount of mycelium, intracellular water, protein, cellulose and other matters, and has the unique features of being viscous, non-flowing, fully dissolved during stirring, high ductility, etc. and has the factors of difficult dewatering, easy production of odorous gas, etc. Generally, the moisture content of the antibiotic wet bacterial residues is not less than 80%, for example, 80-90%.
The inventor performs a large number of fungus dreg treatment tests including a squeezing test, a strip extrusion test, a baking test and the like; the research results show that: the wet fungus residues are placed in the filter bags to be squeezed to have certain squeezability, but intracellular water in the fungus residues cannot be squeezed out, and continuous treatment is difficult to realize; when the wet fungus residues are extruded, the wet fungus residues are easy to break after being extruded for a certain length (more than or equal to 5 cm) and cannot be well molded; baking wet bacterial residues has the problems of intracellular water overflow, scorching of the surfaces of the bacterial residues, burnt smell and the like, and the wet bacterial residues cannot be effectively treated. The traditional mode can not effectively reduce the water content in the fungus dreg and can not realize good forming of the fungus dreg.
The antibiotic fungus dreg recycling treatment method creatively adopts a plane drying mode, namely: firstly, tabletting antibiotic wet fungus dreg, then spreading the obtained fungus dreg tablets on a metal plate, heating the metal plate by a heat source, and drying the fungus dreg tablets by using the high temperature of the metal plate. The research finds that: the slow deep drying can be realized when the fungus residues are treated by the plane drying mode; in the process, intracellular water in the fungus dreg is gradually released and dried, so that the problems of viscosity and the like caused by overflow of the intracellular water are avoided, and the condition that the surface of the fungus dreg is burnt and the like is avoided, so that the quality of fungus dreg products is influenced. The method can mildly and well remove intracellular water in the fungus dreg, can avoid the generation of peculiar smell gas, has good removal effect on residual antibiotics in the fungus dreg, can also furthest reserve nutritional ingredients in the fungus dreg, realizes higher yield, ensures the formability of products and the quality of the products, has natural aromatic smell, is favorable for the subsequent recycling of the fungus dreg, and has the advantages of low production cost, large treatment capacity, simple and convenient treatment process, environmental friendliness and the like.
Specifically, the main purpose of tabletting the antibiotic wet bacterial residues in the step A) is to control the thickness and the size of the bacterial residues during subsequent plane drying, so as to ensure the plane drying effect and the drying efficiency; wherein the thickness of the fungus dreg tablet can be controlled to be 0.4-0.6cm, preferably about 0.5 cm; meanwhile, the area of the fungus dreg tablet can be controlled to be 80-120cm 2 Preferably 100cm 2 . The shape of the fungus dreg tablet is not strictly limited, for example, a rectangular die can be used for tabletting, and the fungus dreg tablet is rectangular at the moment, and can be 20-30cm in length and 4-5cm in width.
In the step B), the metal plate is not strictly limited, so long as the heat is favorably transferred to the fungus dreg tablet, for example, a steel plate and the like can be adopted; the area of the steel plate can be 1000m 2 Above, thereby facilitating mass production. The heat source for heating the metal plate is not strictly limited, for example, conventional heat sources such as hot air, hot steam and the like can be adopted, and particularly, waste heat flue gas of a boiler and a kiln can also be adopted as the heat source, so that the purposes of energy conservation and environmental protection are realized. The arrangement of the heat source is not limited, and the heat source may be disposed below the metal plate for heating, for example. During heating, the heating temperature can be controlled to be 160-180 ℃ and the heating time can be controlled to be 80-100min.
In the treatment method of the invention, the specific process of plane drying (i.e. flat drying) comprises the following steps:
1) And (3) heating:
in the heating section, the temperature of the wet fungus residues is gradually heated to about 100 ℃, and the process needs about 10-15 min.
2) Loose transition:
after the temperature is raised by the temperature raising section, bacterial residues reaching about 100 ℃ are gradually broken, intracellular water is released, a large amount of intracellular water is gushed out, so that the humidity of the bacterial residues is not reduced and reversely raised, the bacterial residues gradually become loose, the fluidity is increased, and the bacterial residues are not suitable for being too thick in the tabletting step, and flow easily and are not easy to uniformly react if the bacterial residues are too thick. In the loose-leaf stage, there is oxidation process of intracellular substances such as cellulose, and the color of fungus dreg gradually becomes dark, and the color of caramel is developed, and meanwhile, aromatic smell is released. The duration of the loose transition period is about 15-20 min.
3) Cracking section:
the fungus dregs passing through the loose-leaf stage have water content reaching more than 80 percent and become loose-leaf state, thus forming a liquid reaction environment; at this time, a small amount of antibiotics remained in the fungus residues are gradually cracked and disappeared under the liquid and high-temperature environment. The duration of the cleavage stage is about 25-30 min.
4) Evaporating to dryness:
and continuously heating the fungus residues passing through the cracking section, wherein the fungus residues are continuously in an evaporation state, the originally released intracellular water is gradually reduced, the fungus residues are gradually dried, and the final water content is adjustable and is generally controlled below 10%. As the mushroom residue is evaporated to dryness, the color of the mushroom residue gradually decreases, the final color is light reddish brown, the color similar to that of beef jerky and the mushroom residue has obvious fragrance. The duration of the steaming section is about 30-35 min.
The whole spreading and drying process lasts for about 80-100 min; the water content of the dry fungus residues after flat drying is less than 10%, and the detection result of antibiotics in the dry fungus residues is negative (fungus liquid detection).
The fungus dreg pieces after being spread and dried can be shoveled off from the surface of the metal plate, and are crushed and molded after being cooled; the specific modes and process conditions of crushing and molding are not strictly limited, and the method can be reasonably set according to the subsequent recycling requirement.
Specifically, the dry fungus residue can be crushed to 200-300 meshes; wherein, the crushing can be carried out by a crusher, and the rotating speed of a cutter head of the crusher can be controlled to be more than or equal to 14000r/min during crushing, and the crushing time is less than 3min.
Further, a roll granulator may be used for shaping the crushed dry fungus dreg into spherical fungus dreg particles with a certain particle size by the extrusion action of a pair of steel rolls with hemispherical pits. The particle size of the fungus dreg particles is not strictly limited, and may be 3-5mm, for example. The optimal particle size of the spherical fungus dreg particles is about 4mm, and the spherical fungus dreg particles can meet a certain roundness and meet the requirements of farmland application. The rolled spherical particles can be inspected and packaged and can be used as farmyard manure subsequently.
The invention also provides fungus dreg particles which are prepared according to the preparation method.
The invention also provides application of the fungus dreg particles in fertilizer, feed, fuel or raw materials.

Comparative example 1
The wet fungus residue in the embodiment 1 is put into a filter bag, and is pressed by applying pressure, water can be slowly discharged in the initial stage of pressing, but the water is difficult to press in the follow-up stage, and the water is not discharged any more; the addition of potassium carbonate to the wet sludge as an electrolyte/coagulant is somewhat improved, but it is still difficult to significantly reduce the moisture content of the wet sludge.
The results show that: the surface bright water of the wet bacterial residues is easy to remove by squeezing, and the intracellular water is difficult to remove by squeezing, so that the water content of the wet bacterial residues is difficult to realize by utilizing a squeezing method.
Comparative example 2
The wet fungus dreg of example 1 was extruded, and the result showed that: the molding of the wet fungus residues can only be maintained about 5cm, and the wet fungus residues are broken when exceeding the length, so that long thin strips/noodles cannot be formed; if potassium carbonate is added into the wet bacterial residues to solidify protein, the method has a certain effect on shaping the wet bacterial residues, the shaping length can be increased to about 10cm, and the wet bacterial residues still break beyond the shaping length. This shows that: the wet fungus residues cannot be subjected to drying pretreatment in a manner of extruding the wet fungus residues into thin strips.
Comparative example 3
The bacterial dreg pieces prepared in example 1 were baked by an oven, which uses a stainless steel tubular electric heater (top heating) provided at the top, and the baking temperature was controlled to be about 170 ℃ and the baking time was controlled to be about 90 min.
The results show that: as the baking proceeds, the wet bacterial residues first become darker in surface color, and then the interior begins to become thinner; during the baking process, the humidity gradually increases (rather than decreases), the interior of the fungus dreg becomes loose, and the fungus dreg becomes thin and has fluidity. Meanwhile, substances similar to brown sugar are melted at high temperature, so that the whole body is more unshaped and is adhered to the grate. As the baking proceeds, the surface of the fungus residue appears burnt, burnt smell, but the interior is still very wet. This shows that: drying by adopting an oven can not be used for invalidating wet fungus residues and carrying out subsequent recycling because of the problems of viscosity and the like caused by overflow of intracellular water.
Comparative example 4
The wet fungus dreg in the embodiment 1 is treated by adopting the existing high-temperature slurry spraying granulation process, and in order to realize subsequent drying, the fungus dreg is put into a pool to be rotten for 48-72 hours, steam is introduced to boil, and meanwhile, the mixture is continuously stirred, and serious malodor is generated in the process, so that the odor in a factory is serious; spraying the treated bacterial dreg slurry into a drying furnace, generating a large amount of smoke with serious peculiar smell in the high-temperature slurry spraying granulation process, wherein the smoke contains a large amount of organic matters, water vapor, dust and the like, the temperature in the treatment process is above 500 ℃, and the protein is burnt, so that singeing-like smell appears, and serious pollution is caused to the surrounding environment; the quality detection results of the products are shown in Table 2.
Comparative example 5
The wet fungus dreg of the example 1 is treated by adopting a composting mode, the fungus dreg is placed in a composting pond, bacteria are utilized for secondary fermentation, the fungus dreg is continuously decayed and is in a liquid state, a large amount of oxygen in the air is required to be consumed in the process, and serious malodor is generated and released into the air. After the treatment for 60 days, the final fertilizer liquid still needs to be concentrated, spray dried and other links to produce solid fertilizer, and the process is complex and the yield is low; after composting, the loss of solid matters in the original bacterial residues is over half, the material loss is serious, and the benefit is poor; the quality detection results of the products are shown in Table 2.
