<p>PURPOSE: An apparatus for treating sewage/wastewater is provide, which is characterized in that suspended media and micro-filter are installed in an oxidation tank for operating organics decomposition and filtering simultaneously. And back-washing is operated by pressure difference of filtering process. CONSTITUTION: The apparatus comprises the following parts: a suspended media(100) for decomposing organics aerobically; several micro-filters(200), equipped with the suspended media(100), for filtering sewage/wastewater through many micro holes(210); a decompression chamber(300), installed at the lower part of micro-filters(200), for discharging filtered water through a pipe(320) by a filtering pump(310); a back-washing part(400) that is composed of a pump(410), pipe(420), and an injector(430); auto-valves(500)(500a), for controlling the filtering pump(310) and the back-washing pump(410), moved by pressure difference of filtered water flowing into the decompression chamber(300); and a diffusing cylinder(600) for supplying oxygen to the suspended media.</p> |
