<p>A wastewater purifying apparatus has a plurality of treatment chambers (4) to (8) for stepwise purifying wastewater discharged from a lavatory, a storage chamber (9) for storing purified wastewater derived from the downstream most treatment chamber (8) at the most downstream position of the treatment chambers, and a purified wastewater storage tank (2). The apparatus also includes: a suction port (an opening part) (40) formed in the upstream most treatment chamber (4) at the most upstream position of the treatment chambers for sucking the wastewater; reflux means having a reflux channel (35) through which the wastewater in the treatment chambers (5) to (8) disposed on the downstream of the upstream most treatment chamber is refluxed into the upstream most treatment chamber (4); and purified wastewater supply means (46) for supplying the purified wastewater in the purified wastewater storage tank (2) into the upstream most treatment chamber (4). The above arrangement enables to perform expedient and sophisticated purification treatment of the wastewater containing sludge components such as sewage discharged from the lavatory, or miscellaneous effluents generated by pulverizing garbage by a disposer, and to simplify a washing operation of the apparatus.</p> |
