NOVELTY - Urban sewage dispersing treatment comprises e.g. subjecting sewage using intermittent circulation upstream pushing method, dividing treating water inlet cycle into drainage stage and reaction stage, passing sewage from water inlet and drainage stage into aeration pool, pushing sewage through pump flow circulation into reaction pool, making reaction pool sludge bed in a fluidization state, stopping, passing from reaction pool into the next water inlet cycle and drainage stage, carrying out reaction by sewage purification part to purifying from the reaction pool and pushing implement drainage.    USE - The method is useful for urban sewage dispersing treatment (claimed).    ADVANTAGE - The method accelerates the mass transfer rate; treats water which contains low concentrations suspended solid and ensures sewage matrix and sludge are in full contact and completely mixed. The device has simple structure and high loading capacity; consumes less energy and area and is economical.    DETAILED DESCRIPTION - Urban sewage dispersing treatment comprises subjecting sewage using intermittent circulation upstream pushing method, dividing treating water inlet cycle into drainage stage and reaction stage, passing sewage from water inlet and drainage stage into aeration pool, transferring sewage from aeration pool into upward reaction pool, pushing sewage through pump flow circulation into reaction pool, making reaction pool sludge bed in a fluidization state, completing reaction, stopping circulation flow reactor, passing from reaction pool into the next water inlet cycle and drainage stage, passing sewage water into next stage, carrying out reaction by sewage purification part to purifying from the reaction pool and pushing implement drainage. An INDEPENDENT CLAIM is also included for device, comprising a aeration pool and a reaction pool. The aeration tank includes the upper part is connected to aerobic area and facultative area. The upper part of aerobic area is set with water inlet and bottom part is set with aeration element. The reaction pool includes buffer area and anaerobic reaction area. The bottom of buffer area is set with pushing pump for sewage circulation pushing. The reaction pool part is set with water outlet port. The bottom of the reaction pool is set with cloth water pipe. The extending cloth water pipe and facultative area is connected to bottom of reaction pool.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the device utilized in the above mentioned method.
