Abstract:
Disclosed is a bioreactor for treating sewage comprising an aerobic tank including a mixing cell for receiving sewage to be supplied from an inlet and mixing the sewage with activated sludge and an aerobic reactor tank in which the activated sludge adsorbs organic substance existing in the sewage; a backwashing cartridge filter for removing floc resulting from growth of the activated sludge adsorbing the organic substance; and an anaerobic tank for carrying out a denitrification process for denitrifying treated water flowed through the backwashing cartridge filter using anaerobic ammonium oxidation (anammox) bacteria wherein the backwashing cartridge filter allows the sewage discharged from the aerobic tank to pass through the cartridge filter and separates the floc and the treated water using difference in size between the floc contained in the sewage and pores in the cartridge filter, and wherein foreign matter adsorbed on the cartridge filter is easily removed by means of washing water to be injected into the cartridge filter.

Claim (Index 16):
A method of treating sewage comprising:\n primarily sedimenting sewage containing sludge to separate the sewage into raw sludge and settled sewage water; allowing organic substance in the settled sewage water separated in the primarily sedimenting sewage to be adsorbed on activated sludge such that the organic substance is separated out of the settled sewage water and carrying out a denitrification process; secondarily sedimenting surplus sludge in the settled sewage water, on which the organic substance has been adsorbed, to separate the surplus sludge from treated sewage water; recovering and discharging the treated sewage water from which the surplus sludge has been layer-separated by being sedimented in the secondarily sedimenting surplus sludge; dehydrating the raw sludge recovered by being sedimented in the primarily sedimenting sewage and the surplus sludge recovered by being sedimented in the secondarily sedimenting surplus sludge; anaerobically digesting the raw sludge and the surplus sludge dehydrated to produce biogas; and removing nitrogen by allowing supernatant containing ammonium to react with anaerobic ammonium oxidation (anammox) bacteria.
