A wastewater treatment apparatus performs both initial rainwater overflow treatment and primary treatment. A wastewater treatment method according to the apparatus, the apparatus modifying an existing primary depositing reservoir to an up-flow high-speed filtration facility, the apparatus using a floating filter and biological filter paper applied to an existing depositing reservoir to perform an initial rainwater treatment. The apparatus can be applied to an existing wastewater treatment facility to eliminate the necessity of installing an additional facility for an initial rainwater treatment facility. The apparatus is further capable of adjusting the flow rate into a biological treatment facility to achieve a target water quality. The apparatus comprises: an up-flow high-speed filtration facility for filtering floating matter contained in wastewater using a floating filter; a sludge holding tank; a biological treatment facility for removing dissolved organic matter contained in the water discharged from the up-flow high-speed filtration facility; and a concentrator.

Wastewater treatment apparatus capable of performing both initial rainwater overflow treatment and primary treatment, and wastewater treatment method according to said apparatus

A wastewater treatment apparatus of the present invention is configured to biologically filter wastewater through multimedia by consecutively performing two stages (the first and second stages) for a multimedia biological filtration process. A carbon source and coagulant are respectively injected during the first and second multimedia biological filtration processes. The first stage multimedia biological filtration process is carried out in anoxic conditions and the second stage multimedia biological filtration process is carried out in aerobic conditions. The media for the first and second stage biological filtration processes are arranged in large-middle-middle large-small size. Thus, the present invention can secure excellent treated water while minimizing loss of water-head by maximizing reflux capability of solids.
