Abstract
The invention discloses a method for producing chlorella for feeding by using livestock excrement, which comprises the following steps: constructing a small methane tank, performing enlarge cultivation on chlorella, cultivating a chlorella mother liquor, culturing in a large pool, harvesting the chlorella, drying, and collecting. The chlorella culture is simple, the livestock excrement used for producing the chlorella for feeding has large application value, waste livestock excrement can be changed into valuable resources, and the cultured chlorella can be used as food, feeds, health products and fine chemicals.
Description
Technical field
The invention belongs to biological technical field, be specifically related to utilize feces of livestock and poultry to produce the method for feeding chlorella.
Background technology
Chlorella contains abundant nutritive value, and Chlorella pyrenoidesa is in the environment growing, and its protein content accounts for 50% of dry weight, and apparently higher than vegetable-protein, and protein quality is high, and albumen indispensable amino acid is up to 62%.If take chlorella albumen indispensable amino acid as benchmark, index is 100%, and animal proteinum essential amino acid index is generally 80-90%, each albumen essential amino acid index 60-80%, all higher than general animal/vegetable protein, have abundant fat, under nitrogen hunger condition, the accumulation of Chlorella pyrenoidesa lipid acid can reach 86% simultaneously, carbohydrate is not less than 20%, chief component cell walls, is the important component part of algae ortho acid, has abundant VITAMIN and trace element simultaneously.Chlorella is extremely suitable for feed preparation.The a large amount of feces of livestock and poultry of annual generation at present, not only enormous amount, and disperse, be difficult to process.Also do not have at present a kind of technology to produce chlorella by the ight soil of livestock and poultry.
Summary of the invention
The object of the invention is to, a kind of method of utilizing feces of livestock and poultry to produce feeding chlorella is provided, feces of livestock and poultry is turned waste into wealth, can also produce feeding chlorella.
The method of utilizing feces of livestock and poultry to produce feeding chlorella provided by the invention, comprises the following steps:
(1) build 10 cubic metres of little methane-generating pits or anaerobically fermenting pond and prepare anaerobic fermented liquid;
(2) chlorella enlarged culturing, is placed in 50ml triangular flask with 1: 1 ratio, expands 500ml to, then expands 5000ml to, then expand 50000ml to, then expand 500000ml to from 50ml, prepares nutrient chemical cultivate according to this order;
(3) cultivation of chlorella mother liquor, builds a cement pit, long 5 meters, wide 2 meters, and dark 0.5 meter, upper cover plastic greenhouse, configures 2 of the calrods of 2000 watts, and one, qi of chong channel ascending adversely machine, inoculates 0.5 cubic metre of chlorella vulgaris, adds 50% cultivation agent, 50% anaerobic fermented liquid;
(4) great Chi cultivates, and great Chi is long 20 meters, wide 2 meters, and dark 0.3 meter, in pond, configure inflator, algae in pond is constantly circulated, make illumination, heat transfer, mass transfer even;
(5) chlorella is gathered, and chlorella was cultivated after a couple of days, in the time of biomass high 5%, gather, the amount of gathering is the half of chlorella nutrient solution, and remaining half is as the mother liquor of cultivating for the second time, so iterative cycles, in suitable season, can gather once for every three days, each 12.5 cubic metres of left and right, after gathering, algae liquid flocculates with flocculation agent, removes supernatant tentatively concentrated, and the bead liquid butterfly centrifugal machine after concentrating separates, obtain algae mud, with collecting after compressor compresses;
(6) dry and collection, wet algae can dry or utilize the sun to dry, and pulverizes, and finally once collects dry algae powder 50-60 kilogram, and season, humidity was applicable to, and can obtain dry algae powder 750-900 kilogram every day.
The method of utilizing feces of livestock and poultry to produce feeding chlorella provided by the invention, its beneficial effect is, chlorella is cultivated simple, produce feeding chlorella with feces of livestock and poultry and there is very large using value, not only can make feces of livestock and poultry make a silk purse out of a sow's ear, and the chlorella of cultivating can be used as food, feed, healthcare products, fine chemistry industry etc.
Embodiment
Below in conjunction with an embodiment, the method for utilizing feces of livestock and poultry to produce feeding chlorella provided by the invention is described in detail.
Embodiment
The feces of livestock and poultry that utilizes of the present embodiment is produced the method for feeding chlorella, comprises the following steps:
(1) build 10 cubic metres of little methane-generating pits or anaerobically fermenting pond and prepare anaerobic fermented liquid;
(2) chlorella enlarged culturing, is placed in 50ml triangular flask with 1: 1 ratio, expands 500ml to, then expands 5000ml to, then expand 50000ml to, then expand 500000ml to from 50ml, prepares nutrient chemical cultivate according to this order;
(6) cultivation of chlorella mother liquor, builds a cement pit, long 5 meters, wide 2 meters, and dark 0.5 meter, upper cover plastic greenhouse, configures 2 of the calrods of 2000 watts, and one, qi of chong channel ascending adversely machine, inoculates 0.5 cubic metre of chlorella vulgaris, adds 50% cultivation agent, 50% anaerobic fermented liquid;
(7) great Chi cultivates, and great Chi is long 20 meters, wide 2 meters, and dark 0.3 meter, in pond, configure inflator, algae in pond is constantly circulated, make illumination, heat transfer, mass transfer even;
(8) chlorella is gathered, and chlorella was cultivated after a couple of days, in the time of biomass high 5%, gather, the amount of gathering is the half of chlorella nutrient solution, and remaining half is as the mother liquor of cultivating for the second time, so iterative cycles, in suitable season, can gather once for every three days, each 12.5 cubic metres of left and right, after gathering, algae liquid flocculates with flocculation agent, removes supernatant tentatively concentrated, and the bead liquid butterfly centrifugal machine after concentrating separates, obtain algae mud, with collecting after compressor compresses;
(6) dry and collection, wet algae can dry or utilize the sun to dry, and pulverizes, and finally once collects 55 kilograms of dry algae powders, can obtain 800 kilograms of dry algae powders every day.
