Description
Technical field
The utility model belongs to the refuse treatment engineering technical field, relates to a kind of equipment for treating organic refuse, especially relates to a kind of efficient back-mixing circulation anaerobic fermentation unit.
Background technology
Developing rapidly of China's economy increases urban population rapidly at present, and living standards of the people improve constantly, and urban restaurant trade is become increasingly prosperous, and the generation of organic waste is unprecedentedly increased.National urban sales of the catering industry in 2006 are 10345 hospitals, and sack was 12,352 hundred million yuan in 2007, every year on average with 17.9% speed increment.Do not comprise small-sized cities and towns, annual more than 2,000 ten thousand tons of the organic wastes that produce in national big and medium-sized cities.
Present stage, utilize organic waste as raw material production biogas, not only efficiently utilize organic waste and related category rubbish the like waste, and can also solve the problem that feces of livestock and poultry class marsh gas raw materials deficiency causes biogas engineering to leave unused.Because the content of cellulose of organic waste is higher, lignocellulose is difficult for decomposing in anaerobic digestion process, and easily layering forms scum silica frost, and is mobile relatively poor, the discharging difficulty.At present, the marsh gas fermentation process for organic waste high cellulose content raw material mainly contains: liquid digestion, solid-state digestion and solid-liquid two-phase digestion process.Liquid digestion techniques has been widely used in the processing of mixing raw material abroad, but because material water ratio is high, and the required digestive organ volume of this technology is larger, heating and stirring energy consumption are high, and microorganism is easily run off with discharging.Because the organic waste solids concn is high, the input and output material difficulty, the digestion of organic garbage methane engineering solid feeds intake as main take sequence batch (, mainly contain overlay film groove dry type, garage (freight container) formula and red-sludge plastic anaerobic digestion process, as: the organic waste high solid weighing apparatus Hair Fixer fermentation methane tank (patent No.: 200620034522.4).Owing to have the characteristics such as aerogenesis peak, low ebb be obvious in the single digestion period, so the sequence batch (biogas engineering adopting mostly the mode of a plurality of different digestion phase reactor parallel connection to move.The problems such as sequence batch (exists generation unstable, and input and output material labour intensity is large, in the situation that the price of labour power increases day by day, this technique more and more is restricted in the application of big-and-middle-sized biogas.Solid-liquid two-phase digestion process separates with methanogenic phase mutually to reach product acid, and utilizes natural pond liquid to reflux and realize circulation inoculation by solid phase and liquid phase fermentation raw material are divided in different zones.According to the difference of number of reactors, separate type two-phase and integrated two-phase anaerobic digestion techniques are arranged.Separate type two-phase technique can be criticized the continuous and steady operation that the digestive organ parallel connection reaches whole system by continuous dosing or a plurality of order that is in different digestion phases of solid phase digestive organ, technique (number of patent application: 201010198942.7) such as a kind of organic waste producing biogas by two-stage anaerobic fermentation, because a plurality of digestive organs being set, cost of investment is higher, and two-phase is difficult to separate fully, produces acid and easily produces mutually methane.The integrated two-phase anaerobic digestion techniques is to realize the continuous anaerobic technique of solid phase and the digestion of liquid phase subregion in same reactor, as: a kind of method (patent No.: 200710061604.7) of the organic waste raw material mixed fermentation of methane bacterium refluxing and pulverizing being produced biogas.This technology by continuity feed intake, discharging so that the biogas production continous-stable, still, discharging is still very difficult.
Organic waste has the characteristics of himself, when carrying out sanitary landfill, has the problems such as floor space is large, secondary pollution, potential safety hazard; Burn the minimizing degree maximum, initial investment and working cost are higher, treating processes may produce the danger wastes such as Dioxins, flying dust, are subjected to common people's degree of awareness to limit and supervise restriction, and burning disposal is appointed right Difficulty; The compost treatment organic solid castoff exists then that heavy metal is difficult to separate, nitrogen loss is serious, energy expenditure is large, the shortcomings such as the high and difficult collection of odor concentration.
Anaerobically fermenting is under anaerobic, and organic matter is carried out the process that decomposition and inversion is CH4 and CO2.Have following advantage: (1) floor space is little, treatment cycle is short; (2) fermenting process can produce methane as clean energy source and high-quality soil ulmin fertilizer; (3) fermenting process is easily controlled, and does not produce secondary pollution; (4) but complete closed process, can not pollute surrounding enviroment.
More to anaerobically fermenting research at present, homogenous anaerobic fermentation and diphasic anaerobic fermentation are arranged; Mesophilic digestion and thermophilic fermentation; Wet type fermentation, dry type fermentation and half dry type fermentation.
Anaerobically fermenting in the past is often for single material, carbon-nitrogen ratio, water ratio, potential of hydrogen etc. are in smaller scope, need the parameter of adjusting many, particularly the single fermentation material can produce feedback inhibition to methanobacteria, as manure fermentation exist ammonia nitrogen concentration high, to methanobacteria and hydrogenogens restraining effect is arranged, the characteristics such as the fermentation load is low and solid holdup is low; Organic waste has that oil content is large, foreign matter is many, solid holdup is high, the characteristics of the easy acidifying of fermentation substrate; Domestic waste has that organic content is low, composition is large with the space-time fluctuation, the characteristics large to the anaerobic system surging force.Establish respectively treatment facility for various wastes in addition, investment is large and be difficult to bring into play the mass-producing effect.Particularly the inhibition factor of single material is obvious, and material adjusting difficulty is very large.
Organic waste carries out anaerobic fermentation after the pre-treatment, can solve that the fermentation materials uniformity is poor, fermentation efficiency is low, the tunning restraining effect, can enlarge simultaneously the biogas scale of producing, promote liquid natural pond, natural pond slag quality, focus on various organic solid castoffs, improve the level of resource utilization, innoxious and minimizing.
Therefore, a kind of new high-efficiency anaerobic ferment devices carries out organic waste anaerobically fermenting and realizes resource utilization, harmless treatment, both can stop from the source harm of swill, can alleviate again the difficult problem of china natural resources shortage.
