Definitions

  • the present disclosure relates to a field of environmental technologies, more particularly to an anaerobic reactor and an anaerobic wastewater treatment process used for wastewater treatment.
  • An anaerobic reactor is a common apparatus used for wastewater treatment, and the anaerobic reactor treats and converts oxygen consumption substances in the wastewater into biogas by means of anaerobic sludge in the anaerobic reactor.
  • the wastewater contains impurities, such as fiber (cow manure) , straw, or the like.
  • COD chemical oxygen demand
  • the wastewater does not undergo a fiber pretreatment before entering the anaerobic reactor.
  • Mixing homogeneity of the wastewater and the anaerobic sludge is an important factor influencing the treatment efficiency.
  • stirring is usually needed in the anaerobic reactor.
  • methods for improving mixing efficiency by stirring have their own problems, which need to be improved.
  • Stirring by compressed gas the compressed gas is introduced into the anaerobic reactor for stirring. This mode of stirring has problems of high energy consumption and high safety requirements for the anaerobic reactor.
  • Stirring by circulating pump wastewater in an upper portion of the anaerobic reactor is pumped to a lower portion of the anaerobic reactor by a circulating pump to produce an upward flow velocity, such that the wastewater and sludge can be flushed upwardly. This mode of stirring has stirring dead zones.
  • Mechanical stirring a stirring paddle is provided in the anaerobic reactor, the stirring paddle is driven to rotate by an electric motor arranged at a top of the anaerobic reactor through a driving shaft.
  • a distance between the stirring paddle and an inner bottom surface of the anaerobic reactor is usually one third of the height of the anaerobic reactor. If the stirring paddle is too close to the inner bottom surface, stirring energy will be lost and energy consumption and costs will increase. If the stirring paddle is too far away from the inner bottom surface, a stirring dead zone (i.e. a zone which cannot be stirred) often occurs on the bottom of the anaerobic reactor, affecting the mixing effect.
  • the present disclosure realizes the problems existing in the conventional stirring ways, and is intended to solve at least one of the technical problems in the related art at least to a certain extent.
  • the present disclosure proposes an anaerobic reactor and an anaerobic wastewater treatment process that does not need stirring and have low energy consumption. Furthermore, the mixing effect of the sludge and the wastewater is good, and the stirring dead zone on the bottom of the anaerobic reactor is reduced, thereby greatly improving the wastewater treatment efficiency.

  • the sludge on the bottom of the reaction chamber is scraped into the sludge collecting groove by the sludge scraper, such that the sludge can be avoided from depositing on the bottom of the reaction chamber, and the mixing effect of the sludge and the wastewater can be improved. Furthermore, no stirring device is needed, so as to overcome problems brought by the conventional stirring ways. Since the driving device for driving the sludge scraper is arranged on the bottom of the tank body, the driving device can be connected to the sludge scraper without the long transmission shaft, such that the sludge scraper operates steadily and has little vibration and noise.
