<p>PROBLEM TO BE SOLVED: To efficiently liquefy and decompose fine raw waste refuse contained in the waste water of garbage ground by a disposer and discharged from a kitchen without producing scum and facilitate the aerobic purifying treatment of org. matter in garbage waste water after liquefying decomposition. SOLUTION: In a garbage waste water treatment method consisting of a liquefying decomposition treatment process, an aerobic treatment process and a sedimentation treatment process, when fine raw waste refuse contained in garbage ground water is liquefied to monomeric matter by anaerobic decomposition bacteria, the part above the almost central part in a liquefying decomposition tank 1 is loosely packed with a large number of carriers composed of polyurethane foam having anaerobic bacteria supported thereon. Garbage ground water containing fine raw waste refuse is passed through the filter bed of the carriers 3 to receive filtering and liquefying decomposition and org. matter in garbage waste water after liquefying decomposition is oxidatively decomposed. At that time, a large number of carriers 6 composed of polyurethane foam having aerobic bacteria supported thereon are floated within an aerobic treatment tank 5 and these carriers 6 and garbage waste water after liquefying decomposition of which the quantity is equal to or more than the total quantity of the carriers 6 are aerated and mixed.</p> |
