At the undesirable weakness of the conventional SBR technology of tradition phosphor-removing effect, the utility model is based on circulating type active sludge method (CAST:Cyclic Activated Sludge System) technology, but takes intermittent water inflow, restricted aeration mode.It is by increasing the waterpower circulation of aerobic biochemical pond 40 mixed solutions in the denitrification stage, strengthen the effect that mixes thereby reach, make denitrification can under the condition of carbon source deficiency, rely on all balanced fully reactions of mud in the pond, reach the purpose that total denitrogenation level increases.Moreover, at the beginning of precipitate phase, carrying out mud simultaneously returns, the amount of returning 15～30%, not only stoped the discharging in advance of phosphorus in the aerobic biochemical pond 40, but also anaerobic phosphorus release be put into the anaerobic pond (biological selecting area) 30 of aerobic biochemical pond 40 leading portions, make dephosphorization and biology be chosen in equalizing tank 30 anaerobic zones and carry out, thereby the phase mutual interference when having avoided denitrogenation dephosphorizing to carry out in same aerobic biochemical pond 40 and the inhibition conflict of bacterial classification make system's phosphor-removing effect better.As shown in figure 10, be the control method schematic flow sheet of the intelligence control system of the utility model SBBR modularization sewage disposal, it specifically comprises the steps:
Step a, fill phase: anaerobic pond 30 sewage enter aerobic biochemical pond 40, actual flooding time t
1＇≤30 minute are higher than any water level of water inlet pipe and the waterhead of water inlet pipe lower edge by detecting anaerobic pond 30, in the hope of aeration scale-up factor K
1, K
1Span is 0≤K
1≤ 1.Equalizing tank 20 is collected the sewage networks water inlet, carries out grid filtration, acidication, homogeneous and all measures, and improves the biodegradability of water inlet, and sewage utilizes the run by gravity effect after this is through the stop more than 3 hours, enter anaerobic pond 30.Mixes with aerobic biochemical pond 40 active sludge that reflux so far at anaerobic pond 30 sewage, polyP bacteria utilizes the carbon source of sewage to carry out endogenic reaction, releases phosphorus, the interior nutritive substance of synthetic cell on the other hand on the one hand, is dephosphorization circulation preparatory condition; Muddy water mixed solution also carries out biological selection activity at this, and aerobic-anaerobic microbe can also be removed a certain amount of organic matter in the substrate, and the sewage mixed solution that collects in this is waited for the beginning in a new SBBR cycle.In the new processing cycle, the fs, anaerobic pond 30 sewage enter aerobic biochemical pond 40.Utilize intake pump 32 to take out anaerobic pond 30 sewage, set flooding time t
1=30 minutes.Because sewage comes amount irregular, can be considered variable, and the design of intake elevation is to decide height on the structure, and sewage time t is taken out on the historical facts or anecdotes border
1＇≤30 minute.Therefore, need detect the air pressure of air lift system by certain hour at interval, as △ P=0, show that anaerobic pond 30 liquid levels are lower than intake, then intake pump 32 idle running should stop into water program, to save energy consumption.
Step b works as K
1＞0.5, enter aeration phase, this aeration phase is divided into 6 trifles, each trifle aeration time t
2＇=15 minute * K
1, to shut down 0-0.35 hour, circulation was stirred 0-0.4 hour.Behind the water inlet end, as record K
1＞0.5, then operational process enters subordinate phase, aeration phase.For the dissolved oxygen content in the accurate Controlling System technical process, but system's aeration is adjustment process.As a kind of selectivity embodiment of the present utility model, aeration phase total time can be 2.5-4.5 hour, is divided into 6 trifles, and each trifle aeration time is about 0.17-0.4 hour.System can realize the accurate control to the dissolved oxygen concentration of different flooding quantity sewage by the adjusting to aeration time, thereby energy-saving and cost-reducing, cuts operating costs.In whole aeration phase, the active sludge of 40 belows, aerobic biochemical pond passes through the organism in good bacteria and the amphimicrobe biochemical degradation sewage under aerobic condition on the one hand, polyP bacteria absorbs the phosphorus in the sewage, make system have dephosphorization function, the accompanying microbial film absorption of ball filler by 40 tops, aerobic biochemical pond and filter substrate in the sewage on the other hand makes organic further degraded.When organic substrate concentration gradient reduces gradually with the passing of aeration time, the nitration reaction in aerobic biochemical pond 40 is enlivened, in each joint dead time of aeration, aerobic biochemical pond 40 is in anoxic condition, as a result denitrification begins to manifest, and sewage begins denitrification process, and denitrification stirs and makes sewage circulation up and down in aerobic biochemical pond 40, fully contact with microbial film and denitrification flora and accelerate mass transfer velocity, thereby make the denitrification denitrogenation action effect better.
Step c, just heavy stage: all air pumps quit work, and make mud reach certain sedimentation ratio in the aerobic biochemical pond.In the just heavy stage, this just heavy time t
3Can be between 0-1 hour.
Steps d, mud returns the stage: pneumatics control mud returns pump operation time t
4=t
1* 20% * K
1, K
1Value 0.5≤K
1≤ 1, make that the variation of the variation of the mud amount of returning and aerobic biochemical pond sewage load is synchronous.This mud returned in the stage, and mud returns pump operation time t
4Can be between 0-0.5 hour, this stage is returned the measure of regularly discharging high phosphorus mud outside system of anaerobic pond 30 and anaerobic pond 30 by high phosphorus sludge, and system finishes the dephosphorization process.
Step e, two heavy stages: sedimentation time is at t
5Set in≤2 hours the scope, in this stage, mud-water separation in the aerobic biochemical pond, sludge settling forms the mud-water separation interface.
Step f, bleeding stage: pneumatics control wet-pit working hour t
6T is worked as in ＇≤0.5 hour
6＇=t
1During ＇, wet-pit quits work.In this stage, water displacement and flooding quantity have functional relation.
Step g leaves standstill the stage: time of repose t
7≤ 1 hour, the microorganism in this stage aerobic biochemical pond was in starvation, and increased activity waits for the next new cycle of operation quietly.
Because the intelligence control system of SBBR modularization of the present utility model sewage disposal adopts Internet of Things remote intelligent control techniques, so said process can both realize remote computer and mobile phone control, also can be by the operation of mobile phone grasp system whenever and wherever possible dynamically.
A kind of specific embodiment as the intelligence control method of the utility model SBBR modularization sewage disposal, can adopts pressure sensor as detecting sensor 74, pressure variation by detecting intake pump 32, wet-pit 404 is in the hope of aeration scale-up factor K1, be converted into water yield parameter through mathematical model, by the computing of SBBR technological mathematical model, obtain the key parameter to system's control again.
(1) control of fill phase: the anaerobic pond 30 that link to each other with equalizing tank 20 this moment is higher than any water level of water inlet pipe 24 and the waterhead of water inlet pipe 24 lower edges is the key parameters that will detect.
Therefore, in described step a, the intake pump 32 atmospheric pressure value Pq of the water inlet pipe 24 lower edge water levels that the last cycle has been recorded are as the calculation constant in this cycle, intake pump 32 starts the intake pump 32 atmospheric pressure value Pt that the beginning water level is surveyed in the back, then has: △ Pn=Pt-Pq, n=1,2,3; By △ P

1≤ 1.When liquid level was lower than water inlet pipe 24 mouth of pipe lower edges, water inlet stopped, and still in idle running, stop signal is the velocity of variation d(Pt of Pt to intake pump 32) be 0, with d(Pt)=0 o'clock Pt value stores reservation, makes the Pq value of next cycle;
Work as K
1＜0.5 o'clock, show that aerobic biochemical pond 40 flooding quantitys are very few, system enters to shut down and treats the water stage that this stage duration is 3 hours.Standby expires, and system intakes again, and asks △ P2=Pt-Pq, but asks the total inflow Q of secondary water inlet
