The method of deposition activity sludge is：When system is normally run, first switch valve 12 is opened, second switch valve is closed
14, excess sludge is extracted from second pond or aeration tank using elevator pump 11, by mud and sewage via the first branch pipe 15 and delivery pipe
Road 17 is pumped into knockout drum 21.Excess sludge sewage is stood 20 ~ 25 minutes in knockout drum 21, makes mud and sewage natural subsidence
There is clarified solution in layering, upper strata, and lower floor is activated sludge, now, and excess sludge natural subsidence layer volume accounts for total sewage quantity
1/50th or so.Then, jet submersible sewage pump 24 is opened, is imported clarified solution by clarified solution jet export part 22 clear
In clear liquid surge tank 23, when the liquid level in clarified solution surge tank 23 reaches exterior liquid level controller 231, pass through programme-control system
System, control clarified solution discharging valve 29 is opened, while controlling efflux pump 61 to start, clarified solution is drained into sewage disposal system.Such as
This is operated repeatedly, and predetermined lower level sensor 26 is enriched with until the excess sludge natural subsidence layer height in sewage reaches
When putting, terminate enrichment procedures, using solid method determine MLSS enrichment content, and based on content record.
Storing the method for activated sludge is：After the basic crack MLSS being enriched with, pump 13 and second switch valve are drawn in unlatching
14, COD treatment sewages will be contained and be injected into via the second branch pipe 16 and conveyance conduit 17 in knockout drum 21, level sensor is reached
Behind the position of device 27, pump 13 and second switch valve 14 are drawn in closing, and sewage of this part containing pollutant can be used as microorganism species institute
A part of nutriment needed is supplied to flora in tank.The sewage containing polluter is changed in good time maintains activated sludge in knockout drum
The nutrition supply of interior flora, determines that sewage changes the frequency, specific method is according to the degradation data determined：Determine within every 30 minutes
COD contents in first separation tank 21, when COD measured values are equal to bioanalysis sewage disposal system COD discharge values, its duration can
It is set as that treatment sewage containing COD changes duration；Auxiliary carbon source is provided by nutrition fluid reservoir 31 simultaneously, bacterium in knockout drum 21 is maintained
The Nutrition and Metabolism balance of group.Meanwhile, the temperature in thermostat unit adjustment knockout drum 21 is 22 ~ 35 DEG C, and in storage activity
During sludge, it is aerated by aerator.During aeration, adjustable float aeration head 41 need to be in knockout drum 21 from top to bottom 1/3rd
In the range of adjustment position, aerobic environment region is formed on the upper strata of knockout drum 21, middle level forms anaerobic environment region, lower floor's shape
Into anaerobic zone, so that different floras are survived.Adjusting the method for the position of adjustable float aeration head 41 is：It is determined that being treated containing COD
Handle sewage to change after duration, adjustable float aeration head 41 is lifted up 3 times, 50mm is lifted every time, selected COD is degraded value
Minimum position is fixed as rational position.In addition, also can adjust the aeration quantity of multiple Independent adjustable aeration pumps 42, prevent
Aeration occurred causes the liquor-saturated oxygen of microorganism or serious deficient aeration to cause microorganism mortality.It can be seen according to by observation window 28
Liquid color adjustment aeration quantity in the knockout drum 21 observed：When bacterial activity is preferable, the liquid in knockout drum 21 is in yellowish-brown
Color；When bacterial activity tends to be poor, the liquid in knockout drum 21 is in dark brown；When aeration quantity is excessive, in knockout drum 21
Liquid tends to be creamy white.When condition of storage control where appropriate, activated sludge flora has 3 ~ 6 times of propagation in 6 ~ 13 days, its
Multiplication rate is reduced afterwards.It is when the bacterial activity life cycle vigorous period is the logarithmic proliferation phase, the activity in knockout drum 21 is dirty
Mud is discharged in sewage disposal system, keeps the validity of activated sludge.The activated sludge of storage is being vented back to bioanalysis sewage
After processing system, efflux pump 61 and high-concentration activated sludge discharging valve 25 are closed, above-mentioned enrichment, the process of storage is repeated, carries out
The culture of next batch activated sludge.
The present invention can be monitored, controlled parameter and the operation of above-mentioned each device by control unit；In the presence of control unit,
The activated sludge of storage, when water treatment system occurs abnormal, is back to by enrichment more than repeating, culture, storage process immediately
In sewage disposal system, quick recovery system degradation capability reaches system stable operation purpose.
