It is interior at two rows and to be sequentially arranged.
The working principle of the multistage combined domestic sewage purification system of the present embodiment are as follows: sewage divides from into sewage pipe 1
Stream enters in branch sewer, and the outlet of branch sewer is located at the bottom in anoxic bio-contact oxidation area, anoxic biology
Catalytic oxidation area is equipped with elastic filler, which is made of high molecular polymer through special wire drawing, has had flexibility and appropriateness concurrently just
Property, spatially homogeneous radiation state arrange, existing certain mechanical strength, the antiacid alkali of biomembrane, it is ageing-resistant, not by water flow shadow
Ring, be conducive to not only microorganism colonization it is fast, it is easy to fall off but will not be fallen off biomembrane blocking, make microorganism in the state of anoxic will
Acidification is hydrolyzed in pollutant, completes the removal of most COD and nitrifies the effect of denitrogenation；Sewage connects by the first anoxic biology
It is overflowed to after touching 101 biochemical treatment of zoneofoxidation in corresponding first aerobic activated sludge zoneofoxidation 102, this area adds aluminium calcium powder+work
Property sludge enables activated sludge, aluminium calcium powder, pollutant sufficient by the aeration effect of aerobic zone bottom aeration branch pipe
It mixes, activated sludge promotes microorganism under the action of the calcium of certain content and aerobic biochemical reduction COD occurs and goes
Except the nitrogen and phosphorus in sewage, while secretion of the active sludge microorganism to extracellular polymeric is promoted, causes Sludge Surface opposite
Hydrophobicity enhancing, muddy water can be easily separated, and improve treatment effect；Aluminium calcium ion can also promote the shape of sludge wadding body by bridging action
At and maintaining the stability of sludge flocculation structure, so that sludge wadding body is caught by net, roll up the effects of sweeping and adsorb and nitrogen phosphorus of degrading
Pollutant, so that total nitrogen and total tp removal rate improve.Sewage after the reaction of the first aerobic activated sludge zoneofoxidation 102 is through bottom
Reflux enters in the second anoxic bio-contact oxidation area 103, and the inclined plate setting of 103 bottom of third anoxic bio-contact oxidation area makes water
Stream evenly distributedly contacts filler and sludge, the raw wastewater entered from branch sewer at the same time are mixed with promotion denitrification
Effect increases denitrogenation dephosphorizing efficiency；Water after reaction enters the second aerobic activated sludge zoneofoxidation 104 from upper end overflow again, this
Area adds iron sponge powder+activated sludge, by the aeration effect of bottom aeration branch pipe, so that activated sludge and pollutant are sufficiently mixed
Splice grafting touching, due to the special spongy stereochemical structure of sponge iron, provides adequate space for the enrichment and growth of microorganism, is biochemical anti-
The collaboration symbiosis of various microorganisms in device is answered to provide good microenvironment；In addition, due to the special chemical ingredient of sponge iron, it can be with shape
At the Fe2 for the nascent state that a large amount of primary batteries, electrode reaction generate+The Fe3 generated with further oxidation+And their hyrate,
Under the effects of precipitating, flocculation, absorption and volume are swept, the P index in water outlet is greatly lowered；But also have both the work of Biology-iron
With having both chemistry except the multifunctional microbial absorption carrier of P and the effect of biological Inner electrolysis, the purification function of activated sludge can be strengthened
Can, reinforce the removal effect of COD, NH3-N in sewage；Water after reaction continues to connect from bottom inflow next stage third anoxic biology
It touches in zoneofoxidation 105, device, reaction, process and the second anoxic biological in third anoxic bio-contact oxidation area 105
It is identical in zoneofoxidation 103, it overflows in third aerobic activated sludge zoneofoxidation 106 after the reaction was completed, aeration branch pipe is arranged at bottom,
It is wood shavings iron+activated sludge in third aerobic activated sludge zoneofoxidation 106, wood shavings iron construction is fluffy with the contact of sewage and gas
Area is conducive to react greatly, and the iron in filler cooperates with processing sewage with anaerobe, and anti-nitration reaction occurs, converts nitrate nitrogen to
Nitrogen achievees the purpose that denitrogenation；Then enter next stage the 4th anoxic biology from 106 bottom of third aerobic activated sludge zoneofoxidation
In catalytic oxidation 107, by nitrogen phosphorus in multistage AO water, concentration is decreased after above-mentioned multiple nitrification and denitrification at this time, so
Setting branch sewer is not intake herein, and continuing hypoxia response reduces organic matter, and upper end water outlet overflow enters macroreticular resin sea
Continuous aerobic biochemical area 108, bottom are arranged aeration branch pipe and are aerated, the spongy stereochemical structure in same macroreticular resin sponge filler,
There is provided adequate space for the enrichment and growth of microorganism, for microorganisms various in biochemical reactor collaboration symbiosis provide it is good micro-
Environment, and macroreticular resin is one kind with the characteristics of adsorbing, and has the high molecular polymer of concentration, centrifugation to organic matter, is inhaled
Attached effect is to pass through its huge specific surface by the Van der Waals force between it and the molecule that is adsorbed and carry out physical absorption
Work, organic substance is selectively adsorbed from solution, is mentioned to reach separation in anoxic/aerobic combination technique final stage
Pure purpose.The bottom in macroreticular resin sponge aerobic biochemical area 108 is equipped with apopore 24 and reflux pump 25, sewage after reaction from
24 reflux of apopore is to sloping plate deposition Disengagement zone 109, while through reflux water pipe 26 water to be back to the first anoxic raw for reflux pump 25
Denitrification is carried out in object catalytic oxidation area 101；Into 109 lower end of sloping plate deposition Disengagement zone water from bottom to top flow through tiltedly
Plate carries out precipitating and is separated by filtration purified treatment, and sludge is isolated in the lower section in inclined plate area；Bottom in all biochemical zones and inclined plate area
Equipped with sludge pipe 42, base sludge above inclined plate by finally having reached the net of environmental protection standard outside 42 discharger of sludge pipe
Water is discharged by overflow weir 9 and outlet pipe 28.
Multistage combined domestic sewage purification system of the invention subtracts since special filler device is without dosing process
The cost for having lacked the cumbersome and medicament for the treatment of process, makes the high degree of automation of sewage treatment facilitate operation, and branch sewer is set
Meter mode makes water intake mode effectively provide nutrition progress biochemical reaction for anoxic microorganism, and multistage Multilevel A/O Technology is A2O
Improved process, also can more reasonable distribution carbon source, reduce investment and operating cost, processing unit and it is simple to operate easily
Row, with stronger impact resistance and the small advantage of occupied area, reduces sewage treatment dress since integration is inside device
