The present invention discloses a kind of preparation method utilizing Chinese medicine slag to produce biogas, relates to a kind of utilization of waste residue of Chinese herbs, belongs to Biomass Energy Utilization field.It is characterized in that: Chinese medicine slag is crushed to 40 orders, access methanobacteria is 10% of Chinese medicine slag total amount, and adjustment carbon-nitrogen ratio is 20 ~ 25:1,10 days treatment times, temperature 53 ~ 55 DEG C; Carry out anaerobic digestion reaction and prepare biogas.Its beneficial effect is: biogas preparation, the equipment that uses are simple, and equipment Operating Management is convenient; Reduce the dependence of town dweller's life to fossil energy, reduce greenhouse gas emission, owing to not containing the toxic gases such as CO in biogas, more favourable to HUMAN HEALTH, obvious environment benefit; And reduce the quantity combusted of stalk, be straw-returning, the sustainable use realizing ploughing in rural area creates conditions; Use biogas to substitute stalk and also can significantly improve farmers' family's living environment, improve the standard of living of peasant, its social benefit and ecological benefits remarkable.
Description
Technical field
The present invention relates to a kind of utilization of waste residue of Chinese herbs, belong to Biomass Energy Utilization field, specifically a kind of preparation method utilizing Chinese medicine slag to produce biogas.
Background technology
Along with developing rapidly of China's Chinese medicine cause, the Chinese medicine slag waste residue amount in big-and-middle pharmacy pharmaceutical factory in all parts of the country increases day by day, and after traditional Chinese medicine extraction, dregs of a decoction discharge and process are the thorny problems of traditional Chinese medicine extraction, and each Chinese medicine manufacturing enterprise will discharge a large amount of dregs of a decoction every day.If these dregs of a decoction are simply deposited in outside, accumulate over a long period, pile up like a mountain, gradually will ferment mildew and rot, maligned, and contaminate environment, works the mischief to the production of the periphery masses and life.The source of pollution that pharmaceutical industry produces are a lot, its Chinese medicine slag is an integral part, before landfill or burning etc. are mainly contained to the treatment process of the dregs of a decoction, the strengthening realized along with technical progress and good manufacture practice for these several years, a part enterprise newly-built or transformation time solve well the dregs of a decoction pollute problem, another part enterprise then utilizes the dregs of a decoction, turns waste into wealth.
Traditional Chinese medicine enterprise, while producing a large amount of Chinese patent medicine, can produce a considerable amount of dregs of a decoction, and dealing carefully with of these dregs of a decoction usually makes producer and environmental administration feel a delicacy about.According to statistics, the quantity discharged of plant medicine slag is often only just up to more than 650,000 tons by China, and only Tianjin pharmaceutical factory just can produce 3000 tons of plant medicine slags every year.The dregs of a decoction are generally wet stock, and very easily corrupt, taste is smelly different.The dregs of a decoction transporting plant area are at present main mainly with stacking disposal, very easily cause severe contamination to surrounding enviroment.The form of early stage Chinese medicine slag process mainly comprises landfill, burning, FX stacking etc.The dregs of a decoction, due to rainwater shower, easily cause the pollution to surrounding enviroment, in the area that ground water table is more shallow, particularly serious on the impact of water quality.In the face of these challenges, the mankind must explore a green sustainable development road, implant low-carbon economy theory, using enterprise as final driving force and executive agent, advance the development of low-carbon economy pattern from links such as production technique, energy expenditure, utilizations of waste as resource.
Summary of the invention
The object of the present invention is to provide a kind of preparation method utilizing Chinese medicine slag to produce biogas, it is main for solving the dregs of a decoction mainly with stacking disposal, very easily causes the drawbacks such as severe contamination to surrounding enviroment.
For achieving the above object, a kind of preparation method utilizing Chinese medicine slag to produce biogas of the present invention, is characterized in that:
1. charging and pre-treatment: Chinese medicine slag is crushed to 40 orders, access methanobacteria is 10% of Chinese medicine slag total amount, and adjustment carbon-nitrogen ratio is 20 ~ 25:1,10 days treatment times, temperature 53-55 DEG C;
2. anaerobic digestion reaction: complete hybrid anaeroic digestor (CSTR) technical process: in adjustment Chinese medicine slag TS concentration 8 ~ 13% scope, after entering CSTR, CSTR adopts mechanical stirring, frequency 50HZ, amplitude 15r/min, temperature 60 °, whole day successive reaction, regulate pH6.5 ~ 7.8, under air-proof condition, produce thick biogas, thick biogas is drawn from fermentor tank;
3. solid-liquid separation: the natural pond liquid after fermentation is discharged from fermentor tank, carries out solid-liquid separation, wherein separating obtained natural pond liquid is recovered.
Described a kind of Chinese medicine slag that utilizes produces the preparation method of biogas, it is characterized in that: describedly prepare H in biogas
2s controls at 100ppm.
A kind of preparation method utilizing Chinese medicine slag to produce biogas of the present invention, its beneficial effect is: the equipment that biogas uses is simple, and equipment Operating Management is convenient; Use as cooking gas in cities and towns, significantly can reduce the dependence of town dweller's life to fossil energy, reduce greenhouse gas emission, owing to not containing the toxic gases such as CO in biogas, therefore use safer, more favourable to HUMAN HEALTH, its obvious environment benefit; Using as cooking gas in rural area, can reduce the quantity combusted of stalk, is straw-returning, and the sustainable use realizing ploughing in rural area creates conditions; Use biogas to substitute stalk and also can significantly improve farmers' family's living environment, improve the standard of living of peasant, its social benefit and ecological benefits remarkable.
