The flow tube 25 that weir 24 communicates is connected；Toilet-flushing sewage enters in the first pond 21, and the particulate matter contained in its sewage is made in gravity
It is upper with lower precipitation, sewage, separation of solid and liquid is realized, sewage enters in the second pond 22 from downflow weir 24, flow tube 25；Then from
The bottom up motion of two pond 22, under turbulent water effect, the seed sludge in the second pond 22 is in suspended state and is mixed with sewage
Splice grafting is touched, and carries out anaerobic fermentation；Then the sewage in the second pond 22 enters in the 3rd pond 23 from downflow weir 24, flow tube 25, from
The bottom up motion of 3rd pond 23, under turbulent water effect, the seed sludge in the 3rd pond 23 is in suspended state and sewage
Mixing contact, carries out anaerobic fermentation.
The three-level anaerobic organism septic tank 2 plays settlement of sewage and anaerobism hair equivalent to the combination of anaerobic pond and sedimentation basin
Sedimentation basin is played a part of in the effect of ferment, the first pond 21, and fermentation is played a part of in the second pond 22 and the 3rd pond 23, so as to reach one
The multiplex purpose in pond, can remove the suspension in fecal sewage can degrade the organic matter of sewage again.
Then the toilet-flushing sewage after being processed through three-level anaerobic organism septic tank 2 enters in overflow balancing tank 3, using elevator pump
31 are lifted into hydrolysis acidification pool 4.Therein, overflow balancing tank 3 is the effect of water inlet before and after reconciling, to three-level anaerobic organismization
