Description
Technical field
The invention belongs to field of environment engineering, be specifically related to a kind of adjustable biochemistry pool and carry out the adjustable AAO technology of water treatment.
Background technology
Biological denitrification phosphorous removal technique in the municipal sewage treatment at present, mainly by following several kinds:
One, traditional AAO technology: traditional AAO technology is a kind of typical dephosphorization and denitrification process; Its biological reaction tank is made up of for three sections ANAEROBIC (anaerobism), ANOXIC (anoxic) and OXIC (aerobic); This is a kind of preposition anti-digestion type BNR technology of pulling flow type; Be characterized in anaerobism, anoxic and aerobic three sections definite functions, boundary is clearly demarcated, can be according to water inlet condition and water outlet requirement; Create and control three sections space-time ratio and operating condition artificially, as long as the carbon source abundance just can reach than higher denitrification percent as required; When carbon source is not exclusively sufficient, then can make improvements.Conventional process flow is seen Fig. 1.
The traditional biological denitrification dephosphorization technique is the arrangement form of anaerobism (A1)/anoxic (A2)/aerobic (O).This is arranged in theory based on a kind of like this understanding; That is: gather the phosphorus mikrobe effectively release the phosphorus level whether fully; Dephosphorization ability for improving system has extremely important meaning, anaerobic zone before can make and gather the phosphorus mikrobe and preferentially obtain carbon source and be able to abundant dilution.There are following three shortcomings in tradition AAO technology: (1) because anaerobic zone ranks forefront, nitrate salt has a negative impact to anaerobic zone in the returned sluge; (2), instead digest to mix occuping minus advantage, thereby influenced the denitrification effect of system at the carbon source branch because the oxygen-starved area is positioned at system middle part; (3) owing to there is internal recycle; Actually in the excess sludge that the common process system is discharged have only a few part to experience complete to put phosphorus, inhale the phosphorus process; All the other then directly get into aerobic zone by the oxygen-starved area without anaerobic state basically, and dephosphorization is disadvantageous for system for this.
Two. inversion A AO technology---anoxic pond is preposition: the design that anoxic pond is preposition, make the carbon source denitrification of nitrate nitrogen contained in the returned sluge in preposition anoxic pond utilization water inlet, reduce to flow into influence to follow-up anaerobic pond.Process flow sheet sees 2.Inversion A AO technological advantage: 1, for dephosphorization: (1) mud is back to anoxic pond earlier but not anaerobic pond, and the nitrate salt in the mud phegma can be shifted to an earlier date denitrification like this, is unlikely to have influence on the releases phosphorus environment of anaerobic stages; (2) whole mud have all been participated in anaerobism to aerobic process, and this is strong to dephosphorization, and common A/O equals part mud not arrive aerobic process through anaerobism fully owing to internal reflux and without anaerobism, is unfavorable for the dephosphorization process of PAOs.2, for denitrogenation: (1) anoxic section is exactly more direct carbon supplied denitrifying bacteria but not PAOs in advance, and this is favourable to denitrogenation; Denitrifying bacteria can only utilize the remaining residual organic carbon source of PAOs in traditional AAO.
The shortcoming of inversion A AO technology: (1) wants to let him be directed against denitrogenation, and his reflux ratio can't effectively improve; Want to let him be directed against dephosphorization, he but can't supply with the too many carbon source of PAOs.Two contradiction is doomed this technology and can only be applied to the lower occasion of nitrogen phosphorus requirement.(2) unite two into one external reflux and internal reflux, origin is good, but it is big a lot of open by settling tank limit return flow ratio.And bigger reflux ratio causes excess sludge slurry thinner, and water ratio is high, is difficult for press filtration.
Three. distortion AAO technology---anoxic pond is preposition+change system's water intake mode: this distortion AAO technology is not only preposition with anoxic pond, and a water inlet part directly branches to anaerobic pond.The insufficient problem of carbon source possibility in the anaerobic pond has been alleviated in this system when reducing the influence of returned sluge to anaerobic pond.Process flow sheet is seen Fig. 3.
More than three kinds of technologies its relative merits are respectively arranged, different quality adopts different processes to handle as required.When the water inlet total nitrogen is higher than normality threshold, and water inlet total phosphorus data just often, adopts inversion A AO art breading effect as shown in Figure 2 better.When the water inlet total phosphorus is higher than normality threshold, and water inlet total nitrogen data just often, adopts traditional AAO art breading effect as shown in Figure 1 better.When water inlet total nitrogen, total phosphorus data occur two highly or under the situation of influent quality normal (ratio of total nitrogen and total phosphorous is normal), adopt distortion AAO art breading effect as shown in Figure 3 better.
Need a kind of adjustable biochemistry pool of design, it can be regulated according to different water quality, carry out the sewage biochemical treatment to use any one technology in 3 kinds of technologies.
