TREATMENT APPARATUS FOR ORGANIC-SOLID-CONTAINING WASTEWATER

摘要

PROBLEM TO BE SOLVED: To provide a treatment apparatus for organic-solid-containing wastewater which can give good treated water by a relativly small-sized apparatus by accelerating the decomposition of organic solids including hardly decomposable organic substances contained in wastewater. SOLUTION: This apparatus is equipped with a solid-liquid separation vessel 11 for separating wastewater containing organic solids into organic solids and a liquid; an aerobic solid treatment vessel 12 for aerobically biologically treating the organic solids; an ozone treatment vessel 13 for subjecting the organic solids treated in the aerobic solid treatment vessel 12 to an ozone treatment; and a liquid treatment vessel 14 for biologically treating the liquid.
