Automatically flow into the setting pot that gathers materials；
(2) the agitated metering of primary biogas slurry flowed into the setting pot that gathers materials is pumped into one-level anaerobic device, in one-level anaerobism dress
Put middle first fermentation 10-15 days；
(3) biogas residue and biogas slurry are separated after first fermentation, obtains two grades of biogas slurries；
(4) two grades of biogas slurries are pumped into secondary anaerobic device secondary fermentation 5-7 days；
(5) biogas residue and biogas slurry are separated after secondary fermentation, obtains three-level biogas slurry；
(6) three-level biogas slurry is pumped into three-level anaerobic device and decomposes digestion；
(7) decompose biogas slurry after digestion and pass through the aerobic filtering of level Four；
(8) biogas slurry after the aerobic filtering of level Four, purifies water into multi-format biology aerobic pond；
(9) biogas slurry enters back into bio-oxidation pond after entering multi-format biology aerobic pond；
(10) enter and regeneration pond be pumped into after bio-oxidation pond, the Water Sproading in regeneration pond is recycled or for irrigating,
It can be used for being rinsed swinery excrement in step (1) during recycling.
In the step (2), through COD (COD), BOD (biochemical oxygen demand (BOD)) degraded in first fermentation biogas slurry extremely
50-60%.
In the step (2), the biogas produced through first fermentation is used to generate electricity, and the waste heat produced that generates electricity is used for：Support pig
Nursing cote is warmed oneself, for installation for fermenting heating, for warmhouse booth heating.
Isolated biogas residue produces pollution-free vegetable melon and fruit through dehydration for warmhouse booth in the step (3) or processing is made
Into organic fertilizer.
Two grades of biogas slurries are through COD (COD), BOD (biochemical oxygen demand (BOD)) in secondary fermentation biogas slurry in the step (4)
Degrade to 70-80%.
Three-level biogas slurry is through decomposing COD (COD), BOD (biochemical oxygen demand (BOD)) in digestion biogas slurry in the step (6)
Degrade to 90%.
The aerobic filtering of level Four includes by-pass filtration, secondary filtration, three-stage filtration, quadrupole filter in the step (7)；It is described
By-pass filtration, secondary filtration, three-stage filtration, quadrupole filter are respectively in by-pass filtration pond, secondary filtration pond, three-stage filtration pond, four
Carried out in the filtering ponds of pole, rubble is inserted in the by-pass filtration pond, and middle sand is inserted in secondary filtration pond, and fine sand is inserted in three-stage filtration pond,
Level Four filtering ponds are inserted with sponge.Pass through the aerobic filter and remove suspended substances SS of level Four.
Stone, porous cinder, sulphur-cake are inserted in multi-format biology aerobic pond form aerobic flora in the step (8).
Aquatic animals and plants are cultivated in bio-oxidation pond in the step (9), the ammonia in biogas slurry is removed by aquatic animals and plants
Nitrogen.
The aquatic animals and plants are the one or more in water peanut, water hyacinth, lobster, loach.
Beneficial effects of the present invention are：First the flushing inflow of livestock and poultry cultivation night soil water is gathered materials setting pot, then divided
Level fermentation, is every time separated biogas residue and biogas slurry during fermentation, COD, BOD in biogas slurry of progressively degrading, improves fermentation efficiency；Just
The biogas that secondary fermentation is produced is for generating electricity, and the waste heat produced that generates electricity is used to support the heating of pig nursing cote, heats, supplies for installation for fermenting
Warmhouse booth heating, realizes recycling for biogas, saves aquaculture cost；Using the aerobic filtering of level Four to the natural pond after fermentation
Liquid is filtered, the water quality in purification biogas slurry；Aerobic flora in multi-format biology aerobic pond is carried out to the organic matter in biogas slurry
Decompose, bio-oxidation pond further absorbs the harmful components in biogas slurry；Finally enter regeneration pond recycling；The present invention is logical
Livestock and poultry cultivation night soil is fermented after first, purified treatment is then carried out to biogas slurry, biogas residue produces nothing through dehydration for warmhouse booth
Public hazards vegetable melon and fruit is processed into organic fertilizer, the biogas slurry recycling after purified treatment, realizes the zero of fecal sewage
Discharge, while effective utilization to excrement.
