<p>PROBLEM TO BE SOLVED: To provide equipment for treating wastewater such as kitchen wastewater capable of effectively treating even oil in kitchen wastewater. SOLUTION: The treatment process using this equipment is for separating a settled solid component and a floating solid component from kitchen wastewater in a first solid-liquid separation vessel 3, performing the settled solid component and floating solid component to biological treatment in an aerobic digestion tank 4 and returning the treated water to the first solid-liquid separation vessel 3. A separated component in the first solid-liquid separation vessel 3 is biologically treated in an aerobic wastewater treatment tank 5, a settled solid component and a floating solid component separated in a second solid- liquid separation vessel 6 is biologically treated in the aerobic digestion tank 4. The water separating the settled solid component and floating solid component in the second solid-liquid separation vessel 6 is discharged to the outside of the equipment as treated water.</p> |
