ADVANCED SEWAGE TREATMENT SYSTEM COMBINED INDUCING SLUDGE REDUCTION TANK WITH MEMBRANE

摘要

The present invention relates to a sludge reduction type advanced sewage treatment device using a separation film and an advanced sewage treatment method using same, wherein the sludge reduction type advanced sewage treatment device using a separation film can obtain the remarkably improved effect of reducing sludge in comparison to existing biological treatments, can reduce costs for treating sewage, and can stably ensure the quality of treated water by combining a sludge reduction inducing tank and a pressure type membrane separating device with a biological reaction tank in order for large-scaled sewage treatment. The present invention provides a sludge reduction type advanced sewage treatment device using a separation film and a sludge reduction type advanced sewage treatment method using same, wherein the sludge reduction type advanced sewage treatment device using a separation film comprises: an anaerobic tank discharging phosphorus from microorganisms to water; an anoxic tank removing nitrogen from raw water; an aerobic tank in which oxidation and nitrification of organic materials in the raw water are performed and sludge absorbs excess phosphorus; a pressure type membrane separating device equipped with a separation membrane so as to separate the raw water into solid and liquid forms by means of the separation film, discharge the treated water, and concentrate the sludge; a sludge reduction inducing tank inducing the sludge that flows in from the aerobic tank to an initial state of inquilinism and transferring a portion of the sludge to the aerobic tank and another portion of the sludge to the anaerobic tank; and a heating device which is adjacent to the sludge reduction inducing tank and maintains the temperature inside the sludge reduction inducing tank at 30 to 35°C.
