Overall current reach plug flow（Stream of pulses）Effect；Reach each water inlet and meet local quick, well-mixed purpose completely,
Guarantee the per share sewage response time in the reactor.
7. modified baffled bioreactor according to claim 5, it is characterised in that：To the sewage for continuously entering, using big
The double siphon cloth tank of specification variable cross-section, realizes that flooding time is extremely short, and water stopping time is longer（This parameter can be according to compartment volume and stream
The parameter designing such as speed determine turn on pump, termination of pumping time）As flooding time is less than 65S, interval time is more than the water intake mode of 15min.
8. modified baffled bioreactor according to claim 1, it is characterised in that：According to ecological island effect, filler is set
Layer, arranges the A Ke with huge specific surface area in anaerobism section and overgrows state filler, and reinforced anaerobic treatment effect is adopted in aerobic section
Bottom aeration head aeration, gas-water ratio 1：1.5～3, filler adopts superfine fibre elastic filler, is covered with each reaction compartments；Anaerobism
3～10h of hydraulic detention time, the height according to sewage load chooses aerobic section 1.5～3.0h of hydraulic detention time respectively；Normal
Under the conditions of temperature, 40% or so COD can be converted into methane.
9. modified baffled bioreactor according to claim 1, it is characterised in that：To high concentration wastewater treatment reactor,
Filler is alternately arranged with volcanic rock or ceramic grain filter using high grade iron-carbon filler, and using more technique compartment quantity；Make
Water quality reaches and is better than design standard；Ferrum carbon filler can also be utilized while having biological treatment function as biofilm carrier
The principle of galvanic element carries out redox reaction to pollutant, reaches the double effectses of cooperative reinforcing；Effluent recycling can be adopted
Mode, effluent recycling ratio is 300%, minimum 10% to the maximum.
10. modified baffled bioreactor according to claim 1, it is characterised in that：As flooding time is short, reaction is stopped
Time is long；So sludge dam, sedimentation effect good, the second pond of common process can be saved；Effluent quality is good；Using detesting
Oxygen-aerobic combination arrangement, reduces COD amount of oxidation as far as possible, not only reduces power consumption and shortens the aerobic reaction time, while subtracting
Lack CO2 discharge, meet sustainable sewage disposal theory calls.
