NITROGEN AND PHOSPHORUS REMOVAL AND REUSE WATER TREATMENT SYSTEM HAVING UPWARD FLUID TYPE CONTINUOUS FILTER

摘要

PURPOSE: A waste water removal and reuse water treatment system is provided to improve the reactivity of a suspended solids-filtering and denitrizing reaction and to improve cleaning performance of a filtering material. CONSTITUTION: A waste water removal and reuse water treatment system comprises an upward fluid type continuous filter(100) filtering waste water. The upward fluid type continuous filter comprises a filtering tank(101), a distribution pipe(103), a double pipe type airlift pipe(105), a cleaning water chamber(106), a cleaning water discharge pipe(107), and a zigzag type cleaning channel(109a). The filtering tank comprises an inlet pipe(103a), discharge pipe(101a), and filtering layer(102) the distribution pipe discharges the waste water to the filtering layer. The cleaning water chamber collects the cleaning water which cleaned a filter material. The zigzag type cleaning channel is installed in the lower side of the cleaning chamber and secondarily cleans the filtered material.
