Description
Technical field
The utility model relates to a kind of organic waste treating apparatus, and more particularly, it is the device of three sections anaerobic digestion methane productions of high solid two-phase of raw material with the perishable organic wastes that the utility model relates to a kind of.
Technical background
Perishable organic wastes mainly refer to live and production process in produce the discarded object of easily corrupt and easily biological-degradable, comprise rubbish from cooking, hogwash, vegetables, fruit and meat packing discarded object etc.Because quickening of urbanization process and growth in the living standard, perishable organic wastes not only significantly increases on absolute yield, and the shared ratio in the rubbish also significantly improves after give birth in the city, and this part rubbish accounts for more than 50% of domestic waste total amount at present.The characteristics of perishable organic wastes maximum are that the moisture and the content of organic matter are higher, and moisture is generally more than 70%, the content of organic matter in butt generally more than 90%.These characteristics makes present main cities domestic rubbish disposal technology all have some problems, and for example, the higher content of organic matter causes producing the greenhouse gases methane of a large amount of polluted underground waters and edaphic percolate and unordered discharging in the landfill process; And higher moisture need be added a large amount of extra auxiliary fuels when causing burning disposal.In fact, sanitary landfills of today is had relatively high expectations to addressing, and occupation of land face ground is bigger, in many big cities, has been difficult to find the place that is fit to sanitary landfills; For burning disposal, owing to there is secondary pollution problems, government and street levels is also held careful attitude to burning disposal at present.Therefore, press for a kind of new non-secondary pollution of exploitation and the little processing mode of floor space.Effective processing to perishable organic wastes can make a significant contribution for urban garbage disposal.The characteristics of high moisture content and high organic content make that perishable organic wastes is more suitable for carrying out Anaerobic Digestion, and can obtain clean reproducible energy (biogas) in disposal of refuse.
Organic matter anaerobic digestion product methane process comprises 4 steps: the outer hydrolysis of born of the same parents, product acid, product acetate and product methane.The outer hydrolysing step of born of the same parents refers to be monose, amino acid, glycerine and LCFA with polysaccharide, starch, dietary fiber, protein and hydrolysis of lipid under poly carbohydrase, amylase, cellulase, protein enzyme and action of lipase; Produce the micromolecular compound that sour step refers to that hydrolysis produces and under the effect of acid-producing bacteria, be decomposed into simpler acetate, propionic acid, butyric acid, pyruvic acid, lactic acid, valeric acid, ethanol and a spot of carbon dioxide and hydrogen; Produce organic acid product (except that acetate) that the acetate step refers to produce sour step and further be converted into the process of acetate, carbon dioxide and hydrogen; Produce the methane step and refer to that acetate generates the process of methane and carbon dioxide and carbon dioxide and hydrogen generation methane.The anaerobic digestion product methane technology of efficient stable need guarantee the balance between hydrolysis acid process and the product acetic acid and methane producing process, the small molecular organic acid that the hydrolysis acid process produces can in time be produced the utilization of methane process, thereby avoid the organic acid accumulation to suppress the interior microorganism of fermentation system, especially to the inhibition of methanogen, because methanogen is lower to organic acid tolerance concentration, when being accumulated to 13000mg/L, organic acid concentration will suppress methanogenesis activity fully.
The perishable organic wastes main component is polysaccharide, starch, dietary fiber, protein, they belong to the material of easy hydrolysis acidification, the hydrolysis rate of producing acid is very fast in anaerobic digestion process, by comparison, producing the methane process is the rate-limiting step of whole anaerobic digestion process, is easy to generate organic acid when causing perishable organic wastes to carry out Anaerobic Digestion and suppresses.Suppress for fear of organic acid, traditional single-phase anaerobic digestion can only be finished under lower fermentation raw material concentration (being lower than 4%), and for the perishable organic wastes as this class of rubbish from cooking, its total solids content is generally 15%～25%.At this moment, not only need to consume a large amount of water and be used to turn down material concentration, and lower material concentration greatly reduces perishable organic wastes Anaerobic Digestion efficient and produces the biogas ability.Therefore, exploitation unrestraint efficient anaerobic digestion process for producing biogas becomes the key of perishable organic wastes minimizing and energy processing.
Summary of the invention
Main purpose of the present utility model is to overcome deficiency of the prior art, and providing a kind of is the device of three sections anaerobic digestion methane productions of high solid two-phase of raw material with the perishable organic wastes, to improve anaerobic digestion stability, treatment effeciency and to produce the biogas ability.
