Ferment reacts, and adds RW enzyme agents to continue to react 5h in 1% ratio after reaction 8h, and reaction adds again the water dilution of 8 times of amounts after terminating,
Stir, it is standby；
(3) by the mixed liquor after dilution in (2) with 14-20m3The speed of/s is passed through in membrane bioreactor to be carried out nitrifying instead
Should, the nitrogen phosphorus substance contained in feces is removed, gained treatment fluid Jing nano modification solid-liquid separation membrane filtrations obtain the excrement after remove impurity
Just, drying and processing is carried out to it, then is recycled.
Preferably, the ethanol mass concentration in described (1) in extractant is 85%.
Preferably, the polydextran gel and thin base polydextran gel are needed at normal temperatures and pressures, are 60- with mass concentration
70% alcohol solution dipping 15h, being stirred continuously expands gel, is washed away to be filtered dry after residual ethanol with salt-free water and reuses.
Preferably, the drying meanss are vacuum drying, and products therefrom is uniform.
Preferably, the microbial inoculum is bacillus cereuss, yeast and Lactobacillus buchneri with 7：2：3 ratio is mixed, institute
Fermentation temperature is stated for 30-45 DEG C, pH regulator scope is 5.3-6.7.
Preferably, the membrane bioreactor is integral type, is capable of achieving the cross-flow reaction effect of face, and floor space is little,
More fully, the film is a kind of new utilization process for suspension polymerization, and adds metallic zinc and obtained ceramic membrane for reaction.
The invention has the beneficial effects as follows：A kind of processing method of swine excrement of the present invention, not only can be in swine excrement
Zoohormone is extracted, and on the one hand can have certain understanding to animal bodies situation by the hormone for extracting, and on the other hand may be used
