Former operational mode is changed to daily 6 cycles of operation, 240 minutes each periods by this stage, wherein intake 5 minutes,
Later be aerated 230 minutes, superficial gas velocity be 0.7-0.9 cm/s, stop aeration after wait for sludge settling start after 2 minutes from
Discharge outlet drains, and water discharge time is 3 minutes, enters next cycle later；It is 0.9 ± 0.1 millimeter that this stage, which can form grain size,
Granule sludge；This stage continues 7 to 10 days.The purpose in this stage is：There is good settleability what is filtered out on last stage
On the basis of the activated sludge of energy, shearing force is controlled in a smaller range by adjusting aeration quantity, is promoted compared with small particle
The formation of granule sludge, while the small particle sludge of initial stage formation can be protected not destroyed by larger shearing force.
Phase III controls aeration quantity, obtains the aerobic particle mud that grain size is 1 millimeter to 8 millimeters：
This stage running mode is daily 6 cycles of operation, and 240 minutes each periods exposed later wherein intaking 5 minutes
Gas 230 minutes, superficial gas velocity are adjusted to 0.7-1.5 cm/s to regulate and control the size of shearing force, wait for sludge heavy after stopping aeration
Drop started to drain from discharge outlet after 2 minutes, and water discharge time is 3 minutes, enters next cycle later；This stage can form grain size
1 to 8 millimeter of granule sludge, this stage continue 5 to 10 days.The purpose in this stage is：In tiny formed on last stage
On the basis of grain sludge, the size of shearing force is controlled by adjusting aeration quantity, further promotes the formation and increasing of granule sludge
It is long, finally obtain the aerobic particle mud of desirable particle size.
In the above three stage, the water surface elevation after water inlet higher than gas phase separation deflector (6) and is less than overflow port (8)；
The water surface after water outlet is located at water outlet.
Based on the above-mentioned technical proposal, it is an advantage of the invention that：
1) it is provided with dual chamber partition board (12), the ratio of height to diameter of reactor can be increased, enhance mud mixture in reactor
In circulation；2) it is provided with gas phase separation deflector (6), the circulation trend of mud mixture can be increased, while mud can be made
The surrounding that gas in water detaches deflector from gas phase is overflowed, and has achieved the effect that gas phase detaches；3) it is double up and down to be provided with contraposition
Inclined mouth type hydraulic balance mouth (13) can effectively make the hydraulic balance in two Room of culture apparatus, heavy caused by avoiding thus
Shallow lake sludge disturbance, while Double-oblique mouth can effectively stop that gas and muddy water influence the circulation shape of mud mixture in dual chamber up and down
State；4) it is provided with arc-shaped surface water conservancy diversion storage mud plate (14), the resistance of sludge circulation can be effectively reduced, be provided simultaneously with storage
The effect of sludge spoil disposal；5) it is provided with the vertical aeration tube of elbow (16), can effectively reduce aeration muddy water circulation in this way
Effect, increase the power of muddy water circulation.
The incubation of aerobic particle mud is clearly divided into three phases by fast culture process, for each stage
Different sludge qualities and state provide corresponding mode of operation, can effectively and rapidly turn out be not easy to disintegrate, grain
The controllable aerobic particle mud of diameter.

Mouth draining, water discharge time are 3 minutes, enter next cycle later；This stage can form that grain size is 0.9 ± 0.1 millimeter
Grain sludge；This stage continues 7 to 10 days.The purpose in this stage is：It is being filtered out on last stage with good settling property
On the basis of activated sludge, shearing force is controlled in a smaller range by adjusting aeration quantity, is promoted compared with small size particle
The formation of sludge, while the small particle sludge of initial stage formation being protected not destroyed by larger shearing force；
Phase III controls aeration quantity, obtains the aerobic particle mud that grain size is 1 millimeter to 8 millimeters：
This stage running mode is daily 6 cycles of operation, and 240 minutes each periods were aerated 230 later wherein intaking 5 minutes
Minute, superficial gas velocity is adjusted to 0.7-1.5 cm/s to regulate and control the size of shearing force, waits for sludge settling 2 to divide after stopping aeration
Start to drain from discharge outlet after clock, water discharge time is 3 minutes, enters next cycle later；This stage can form grain size 1 to 8
The granule sludge of millimeter, this stage continue 5 to 10 days；
In the above three stage, the water surface elevation after water inlet higher than gas phase separation deflector (6) and is less than overflow port (8)；Water outlet
The water surface afterwards is located at water outlet.
