    • The present invention relates to a continuous-flow water purification apparatus and a water purification method using the same. The continuous-flow water purification apparatus comprises a pumping part for supplying supply water; a membrane filtration part installed at the downstream of the pumping part to filter the supply water with a separation membrane; a backwashing part installed at the downstream of the membrane filtration part to backwash the separation membrane; and a flow control part installed on the membrane filtration part to control the flow of treated water. Therefore, the present invention can increase the space efficiency of the whole water treatment process by eliminating obstacles in the flow of treated water of the water treatment process, can prevent secondary pollutions generated by stay in a storage, and can increase the energy efficiency of the water treatment process by supplying a constant flow without a separate driving facility for compensating for driving power for driving a pollution removal process at a rear end.

    • A method for treating recycle water of wastewater treatment is provided to secure stable quality of effluent by simultaneously reducing a nitrogen load due to the recycle water of wastewater treatment and preventing the recycle water from having bad influences upon a water treatment system such as release suppression of phosphorous from an anaerobic tank and impediment of denitrification in an anoxic tank. In a method for treating recycle water of wastewater treatment, comprising a first settling process, a microorganism treatment process, a second settling process, a sludge returning process, a sludge treating process, and a recycle water treating process, wherein an anoxic tank of the microorganism treatment process is divided into a first anoxic tank(30) and a second anoxic tank(35), the method further comprises: a first denitrifying process of returning the recycle water nitritated in the recycle water treating process to the first anoxic tank to convert nitrite of the recycle water into nitrogen gas; and a second denitrifying process of returning internal return water returned from an aerobic tank(40) to the second anoxic tank to convert nitrate into nitrogen gas. The method further comprises dividingly flowing influent settled through the first settling process into an anaerobic tank(20), the first anoxic tank, and the second anoxic tank to supply a carbon source required for phosphorous release and denitrification.
