The 3rd purpose of the present invention provides a kind of method for preparing substratum for breeding earthworm.
The 4th purpose of the present invention provides a kind of method for preparing fertilizer for plantation forage grass.
The 5th purpose of the present invention provides a kind of method for preparing pollution-free energy source for generating.
" technician " can draw its other purposes of the present invention after reading the application under the enlightenment of present specification.
The invention provides a kind of method of gradient treating organic wastes, this method comprises: the method for gradient treating organic wastes is characterized in that this method comprises:
(1) organic waste is carried out anaerobically fermenting;
(2) biogas of fermentation back generation is used for generating, and the methane-generating pit rest part precipitates, and the slag charge of precipitation gained is made the Twospore Mushroom substratum;
(3) tankage after the Twospore Mushroom results are made earthworm feedstuff.
The invention provides a gradient treating organic wastes method again, this method is for handling carrying out described anaerobically fermenting after the organic waste pre-treatment again.
Described organic waste are pig and/or cow dung.
The invention provides the 5th gradient treating organic wastes method, the waste liquid of described anaerobically fermenting and wormcast are used to plant forage grass.
Method provided by the invention utilizes anaerobic digestion techniques for example to handle cow manure, produces biogas, marsh gas power generation; Natural pond slag plantation Twospore Mushroom, mushroom tankage breeding earthworm; Wormcast mixes also field kind forage grass with natural pond liquid, and the forage grass cowboying forms a kind of optimum ecological circulation system.All linked with one another, be benefited successively, really realized the waste material maximum using.
In view of the pig of collecting, cow dung are contained impurity such as a large amount of fibers, xylogen and silt in just.Pig, cow dung just and wash-down water change with weather and environment, therefore, carry out need carrying out before the anaerobic digestion necessary such as usual pre-treatment such as desilting, water quality, the water yield, temperature adjustment, to guarantee that subsequent anaerobic digestion normally moves.
Anaerobic digestion can get three kinds of products, biogas, natural pond slag and natural pond liquid, biogas is used for generating, natural pond liquid is used for kind of a feed, the natural pond slag is used for the culture material of bisporous mushroom, traditional fermentation is based on " aerobic fermentation ", cycle reaches January, and labour intensity is big, and energy waste is many, fermentative processing before and after the sowing, be the artificial and two spore bacterium technical finesse processes of the organism of fermentation death of striving property unexpectedly theoretically,, wherein exist multiple microorganism based on the anaerobism kind by the natural pond slag that obtains after the anaerobism " fermentation ", being exposed in the air several minutes promptly can be dead, reaches the treatment effect of spontaneous fermentation like this.Through the natural pond of anaerobically fermenting slag, be the high quality raw material of cultivating bisporous mushroom, really realize non-polluted cultivation.
The mushroom tankage are fed earthworm, and wormcast and natural pond liquid are used to plant forage grass, and fresh high-quality forage grass is fed milk cow, has not only guaranteed the output of milk cow, and has guaranteed the quality of milk.
Pig and/or cow dung just digest the biogas that produces the back and are used for generating, than its fund return rate height that directly burns of raw coal as an alternative, be on the one hand since the livestock and poultry farms in scale majority away from cities and towns, the construction cost height of distance and gas line network; The calorific value that is one cubic metre of biogas on the other hand is only suitable with one kilogram of raw coal.And plant is the large electricity consumer, and the waste heat of generating is used for fermentation raw material intensification, insulation or mushroom house and heats up, and this has not only improved the economic worth of biogas self, has alleviated the sharp contradiction of local power shortages again.
