PROBLEM TO BE SOLVED: To quicken garbage treatment and to make a treating device compact by crushing garbage by a crusher along with water to form a concd. org. sewage, adding an org. matter decomposing enzyme to the sewage and decomposing the org. matter anaerobically and then aerobically. SOLUTION: The garbage discharged from a sink inlet 1 is crushed by a crusher 2 along with water and then introduced into an enzyme reaction tank 3, and an appropriate amt. of enzyme is dripped from a decomposing enzyme storage tank 32 in accordance with the operation of the crusher 2 and stored. A raw org. sewage charged into the reaction tank 3 overflows a weir into a first anaerobic treating tank 41 and anaerobically decomposed, and the treated liq. is introduced into a second anaerobic treating tank 42 , treated in the same way and separated by a solid-liq. separation means. The liq. component is introduced into aerobic treating tanks 51 and 52 , aerated with air to further biologically decompose the org. matter. The treated liq. is introduced into a final settling tank 6, and the supernatant is discharged into a sewerage from an outlet pipe 7. |
