Definitions

  • the invention patent relates to a sewage treatment reactor.
  • ⁇ 2 /0 and SBR are common processes with high denitrification and dephosphorization.
  • SBR has limited the development of this process due to its high automation and intermittent effluent issues.
  • the traditional ⁇ 2 /0 process for nitrogen and phosphorus removal is not complicated.
  • the anaerobic, anoxic and aerobic three-stage process formed by the improvement of traditional activated sludge can not only effectively remove organic matter, but also simultaneously remove nitrogen. phosphorus.
  • the existing ⁇ 2 /0 also has the problem that the efficiency of nitrogen and phosphorus removal is difficult to be further significantly improved. There are two reasons for this: (1) the existence of carbon source competition for denitrification and phosphorus removal; (2) the presence of microbial phosphorus release and The problem of low phosphorus absorption capacity.
  • the specific analysis is as follows:
  • the existing ⁇ 2 /0 process nitrogen and phosphorus removal is closely related to the reflux ratio. Too low reflux ratio is difficult to have the ideal nitrogen and phosphorus removal efficiency, but too high reflux ratio is also due to the high concentration of DO in the oxygen-deficient (defective) oxygen section, which is difficult to have high denitrification effect and phosphorus release capacity. Therefore, the existing A 2 /0 process controls the reflux ratio of the sludge and mud-water mixture to a lower value, and the ability to release rock and absorb phosphorus is small.
  • the DA 2 /0 reactor has the following characteristics:
  • the present invention integrates a hydrolysis acidification tank before A 2 /0.
  • Most of the poorly soluble organic matter and macromolecular organic matter in the wastewater during hydrolysis and acidification can be degraded into soluble organic matter and small molecular organic matter under hydrolysis and acidification, which can effectively avoid the problem of insufficient A 2 /0 carbon source. This is another key factor for efficient nitrogen and phosphorus removal in the DA 2 /0 reactor.
  • the DA 2 /0 reactor integrates the principles of the A 2 /0 process and the SBR process. Overall, the DA 2 /0 reactor has a significant A 2 /0 sludge reflux system and nitrification reflux characteristics; from a local perspective, the DA 2 /0 anaerobic, anoxic tank replacement operation has a similar SBR Process influent period, reaction period, sedimentation period and drainage sludge discharge stage. This is a possible factor for efficient nitrogen and phosphorus removal in the DA 2 /0 reactor, which needs further investigation.
  • test results of more than 12 months show that the DA 2 /0 reactor is stable and has a high sewage treatment effect, and its COD, nitrogen and phosphorus removal efficiency is much higher than the existing A 2 /0 and SBR processes. .
  • the DA 2 /0 reactor of the invention has the technical advantages of high efficiency of nitrogen and phosphorus removal, stable effluent quality and minimal residual sludge yield, which cannot be replaced by other sewage treatment technologies in a short period of time, which will also make The promotion and application of this technology has long-term market guarantee.
  • the DA 2 /0 reactor study has not been reported yet, and it is the first.
  • the purpose of the present invention is to provide a two-stage anaerobic anoxic replacement operation of a DA 20 sewage treatment reactor, which is characterized by comprising a water tank (1), an acidification tank (2), an anaerobic tank (4), and anoxic acid.
  • the domestic sewage in the water tank (1) passes through the acidification tank (2) in turn, which is tired.
  • the oxygen pool (4), the anoxic tank (5), the aerobic tank (7) and the secondary settling tank (9) receive purified water from the water outlet (15), and the sludge is discharged from the sludge of the secondary settling tank (9). Mouth (14) is excluded.
  • the acidification tank (2) has a suspended membrane packing (3), and the anaerobic tank (4) and the anoxic tank (5) each have a stirrer (6), and the aerobic tank (7) has an aeration Head (8).
  • the aerobic tank (7) has a vacuum pump (12).
  • the acidification tank (2), the anaerobic tank (4), the anoxic tank (5) and the aerobic tank (7) each have a sludge discharge port (10).
  • the acidification tank (2), the anaerobic tank (4), and the anoxic tank (5) each have two series.
  • the process principle is as follows: the influent water is passed through a constant flow pump to a hydrolysis acidification tank provided with an elastic three-dimensional filler, and the hydrolysis acidified bacteria degrades the macromolecular organic matter and the poorly soluble organic matter in the sewage into small molecular organic substances and easily degradable organic substances; and then flows to the phase A phase.
  • the nitrification liquid and the sludge refluxed in the aerobic tank and the sedimentation tank are stirred in the mixer to make the activated sludge microorganisms sufficiently contact with the pollutant matrix in the sewage to cause organic matter degradation, denitrification and release.
  • the acidification tank (2), the anaerobic tank (4), the anoxic tank (5) and both have two series, and when one of the phases is in operation, the other phase is in a resting state. The next time you change the operating state, the opposite is true. Throughout the test process, the two series of successively replaced the operation to achieve the purification of sewage.
  • the DA 20 described in this patent represents two series of anaerobic anoxic replacement operating A70.
  • the structure of DA 2 /0 is characterized by the design of two independent series of sludge return systems and nitrifying liquid reflux systems.
  • the two series of alternate operation modes have largely solved the belt from the nitrifying liquid.
  • the DO in the anoxic tank affects the effect of denitrification and denitrification, thereby ensuring efficient denitrification in the system.
  • the reflux ratio R of the larger flow rate is a key factor. The result will inevitably ensure that one of the phases of the system is normally influent and maintains phosphorus and nitrogen removal. At the same time, the phase in the resting phase undergoes excessive phosphorus release and sufficient denitrification due to excessive hypoxia.
  • the present invention integrates a hydrolysis acidification tank before A 2 /0.
  • Most of the poorly soluble organic matter and macromolecular organic matter in the wastewater during hydrolysis and acidification can be degraded into soluble organic matter and small molecular organic matter under hydrolysis and acidification, which can effectively avoid the problem of insufficient A 2 /0 carbon source. This is a key factor for efficient nitrogen and phosphorus removal in the DA 2 /0 reactor.
