Embodiment 1
[0036] The integrated gas internal circulation anaerobic baffle membrane bioreactor is a cuboid, and the length ratio of the anaerobic baffle reaction zone to the anaerobic membrane bioreactor is 1:3.
[0037] The anaerobic sludge is inoculated according to the different sludge concentrations in the anaerobic baffle reaction zone 1 and the anaerobic membrane biological reaction zone 17 . Pump the pig farm waste water (COD=10000-15000mg / L, SS=1000-2000mg / L) from the water inlet 5, pump it to the first compartment of the anaerobic baffle reaction zone 1, and then pass through the second compartment (each compartment passes through the downflow zone and upflow zone in turn), the removal rates of COD and SS are 90-93% and 75-80% respectively, that is, after COD and SS pass through the anaerobic baffle reaction zone, they enter the anaerobic The concentration of membrane bioreaction zone 17 is respectively 700-1500mg / L and 200-500mg / L; Pig farm waste water will pass through grid 7 ...
Embodiment 2
[0040]The integrated gas internal circulation anaerobic baffle membrane bioreactor is a cuboid, and the length ratio of the anaerobic baffle reaction zone to the anaerobic membrane bioreactor is 1:3.
[0041] The anaerobic sludge is inoculated according to the different sludge concentrations in the anaerobic baffle reaction zone 1 and the anaerobic membrane biological reaction zone 17 . Pump cattle farm wastewater (COD=20000-22000mg / L, SS=25000-28000mg / L) from water inlet 5, pump to the first compartment of anaerobic baffle reaction zone 1, and then pass through the second compartment (each compartment passes through the downflow zone and upflow zone in turn), the removal rates of COD and SS are 85-90% and 80-85% respectively, that is, after COD and SS pass through the anaerobic baffle reaction zone, they enter the anaerobic The concentration of membrane bioreaction zone 17 is 2000-3300mg / L and 3750-5600mg / L respectively; Cattle farm waste water will pass through grid 7 when e...
