Abstract: Disclosed herein is an apparatus for filtering sewage and wastewater. The filtering apparatus has a vertical structure including a filtering belt comprising a filter bag or a filter mesh that can filter out fine impurities. For this, the filtering apparatus includes a drive motor that receives power to drive the apparatus, an upper drive drum that is operated by the drive motor, a lower rotating drum that is interlocked with the upper drive drum, and a filtering belt that is wound and rotated around the upper drive drum and the lower rotating drum. The filtering apparatus cannot only filter out fine impurities less than from 0.1 mm to 0.2 mm but also separate earth and sand, unlike conventional filtering apparatuses that cannot conduct them.

Abstract: An apparatus for treating sewage using a semi-batch process is provided. The apparatus may include an aeration tank, a thickening tank, a dephosphorization tank, and first and second reactor basins. The first and second reactor basins may each include an opening portion formed by opening a side wall thereof so as to be connected with a lateral portion of the aeration tank and an aeration unit installed therein. The apparatus may also include a flow distribution pipe including a start pipe and a pair of flow pipes, a pair of stirrers each provided at a respective side of the auxiliary pipes in each of the pair of flow pipes, operating in turn to stir the dephosphorized sewage overflowing from the dephosphorization, and a decanter installed across the top of the side opposite to the opening portions of the first and second reactor basins.
