Background technology
Along with the fast development of livestock breeding breed scale, the environmental pollution that farm animal excrement causes is serious day by day, and Chinese annual farm animal excrement generation has reached 1,900,000,000 tons at present, has surpassed 2 times of industrial solid castoff discharge capacity.Existing farm animal excrement treatment technology effect is unsatisfactory, because moisture height in the farm animal excrement, volume are big, the disposal cost height, therefore most of farm animal excrement is directly discharged, if but farm animal excrement is drained into river, lake, then can make body eutrophication, pollute, if and directly stack with solid form, then can take a large amount of soils, the poisonous and harmful substance that the farm animal excrement fermentation produces also can cause air and phreatic pollution, and therefore, the processing of livestock breeding farm animal excrement has become a great problem of enterprise.
And owing to the demand of people to green, environmental protection food, plant husbandry is at present also being sought the substitute that substitutes inorganic fertilizer.
The utility model content
In view of this, in order to address the above problem, the utility model provides a kind of agricultural little ecological zero-emission cogeneration system, can carry out harmless treatment to farm animal excrement, and the excreta after the processing can be used as the fertilizer of plant species.
The purpose of this utility model is achieved in that the little ecological zero-emission cogeneration system of agricultural, comprises the greenhouse, is provided with its feeding house and plant planting facility in the described greenhouse, and described its feeding house ground is provided with the microbial fermentation layer.
Further, described microbial fermentation layer thickness is 50-100cm;
Further, the thickness of described microbial fermentation layer the best is 80cm;
Further, also be provided with water body in the described greenhouse, the area of described water body is the 8-70% of greenhouse area;
Further, be provided with automatic feeding and drinking-water system in the described its feeding house;
Further, the area of its feeding house is less than or equal to plant planting facility area;
Further, be provided with heat-conducting system in the microbial fermentation layer of described its feeding house;
Further, described heat-conducting system is many water pipes.
The little ecological zero-emission cogeneration system of agricultural of the present utility model, farm animal excrement are by after the microbial fermentation layer fermentation process, and for plant species provides abundant fertilizer, the temperature that fermentation simultaneously produces is that good condition has been created in livestock and poultry and vegeto-animal growth; By dispensing probiotics and medicine in the microbial fermentation layer, can ferment fast to farm animal excrement, harmless treatments such as decomposition, absorption, desinsection, the ovum that goes out, passivation; Simultaneously, the carbonic acid gas that farm animal excrement fermentation and livestock and poultry and aquatic products produce can make photosynthesis of plants abundant again, is beneficial to plant growing; The oxygen that plant discharges can improve the air quality of livestock and poultry house.Aquatic products can be cultivated microorganism again.In addition, the utility model also has following advantage:
1) economize ground, livestock and poultry and plant species form the ecosystem closely, do not need the outer soil of occupying volume to handle the excrement dirt simultaneously, and 10-20% saves the area;
2) water-saving, its feeding house does not need the water flushing, water saving 85-90%;
3) growth under the nutrient environment that the farm animal excrement fermentation provides of material-saving, the edible thalline in the microbial fermentation layer can be used as the high-quality feed of livestock and poultry rapidly, improves meat, saves feed 20-30%;
4) energy-conservation, because the heat that fermentation produces and the heat insulating ability in greenhouse can save energy 10-20%, under the microbial fermentation layer, heat-conducting system is set simultaneously, can regulate the cogeneration system temp. and humidity, promote animal and plant growth, also can be peasant household hot water is provided;
5) economize medicine, the useful thalline in the microbial fermentation layer can reduce the incidence of disease of livestock and poultry, and the damage by disease and insect of the plant species of application of organic fertilizers also can reduce;
6) economize fertilizer, the carbonic acid gas that livestock and poultry are breathed out can promote the growth of plant species, makes its Net Photosynthetic Rate reach 29.43 micromoles/square metre second, more than 2 times of Da Putong greenhouse, and the oxygen of photosynthesis generation simultaneously also can promote the growth of livestock and poultry;
7) all degraded utilizations in system of zero-emission, farm animal excrement and plant waste do not have sewage and ight soil outwards to discharge, and can not produce foul smell yet, greatly improve environment.
Other advantages of the present utility model, target, to set forth in the following description to a certain extent with feature, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.
Referring to Fig. 1, the agriculture little ecological zero-emission cogeneration system of present embodiment, comprise greenhouse 1, described greenhouse 1 can adopt plastic tunnel or miniature greenhouse, be provided with at least a in its feeding house 2 and water body 3 or the plant planting facility 4 in the described greenhouse 1, the area of its feeding house is less than or equal to plant planting facility area, referring to Fig. 2, described its feeding give up 2 ground or be arranged with the microbial fermentation layer 5 of 50-100cm, the thickness of best microbial fermentation layer 5 is 80cm, microbial fermentation layer 5 can be selected sawdust for use, agricultural byproducts waste materials such as husk, add the go out Chinese herbal medicine of ovum of microbe leaven and desinsection therein, earthworms etc. are breeded fish in the water body 3, and fish is to make system fertile and that cultivate microorganism, also can regulate simultaneously the microclimate environment in the greenhouse, for livestock and poultry supply drinking water and provide the growth water for plant.Be provided with heat-conducting system in the microbial fermentation layer 5 of described its feeding house 2, described heat-conducting system is made up of thermal conductive water pipe 6, and thermal conductive water pipe 6 feeds cold water, can get up to regulate the effect of temperature, and it can derive hot water in winter, can make the cooling of fermentation bed summer; Also be provided with automatic feeding and drinking-water facility in the described its feeding house 2.Described water body 3 is provided with automatic water supply system.
The agriculture little ecological zero-emission cogeneration system of present embodiment, make livestock and poultry, microorganism and water body, plant species be combined into microecosystem, livestock and poultry and aquatic products excreta are handled the fertilizer of back as plant species, plant species is as livestock and poultry, aquatic products foodstuff, realize zero-emission, efficient energy-saving.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and obviously, those skilled in the art can carry out various changes and modification and not break away from spirit and scope of the present utility model the utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, intention then of the present utility model comprises these changes and modification interior.
