The treatment in stage, and, it is necessary to be circulated treatment to sewage, so repeatable above-mentioned cycle period is walked in actual mechanical process
Suddenly, other states are realized by controlling the start and stop of the inlet duct, aeration stirrer of each treatment region to coordinate, is completed whole
Individual circular treatment.
Preferably, sludge pump 41 is set in the fourth process area 40, after step 5, starts sludge pump, make the everywhere
Non-return valve 80 between sludge in reason area 40 passes through in the treatment region 10 of fourth process area 40 and first is come back at first
In reason area 10.Contain substantial amounts of microorganism and organic matter because carrying out abundant reacted sludge in fourth process area 40, with one
Fixed activity, it is also in itself a process for allowing microorganism to accelerate breeding that the sludge of backflow can play a part of inoculation backflow.And
If sludge does not flow back, the disposal ability of new sludge is limited, influences whole extent of reaction.Need also exist for explanation is any
After being alternately present by states such as aerobic or anoxic or anaerobism in one treatment region, i.e., the technological process in the treatment region is complete
Into.In addition, can place sludge pump in corresponding treatment region, after technological process completion in each treatment region, sludge pump can
Sludge in each treatment region is taken away.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
