APPARATUS AND METHOD FOR WATER AND WASTEWATER TREATMENT USING DISSOLVED OZONE FLOTATION AND PRESSURIZED OZONE OXIDATION

摘要

According to the invention, the solid-liquid separation tank for removing the solids in the raw water; A first bioreactor for microbial treatment of raw water treated in the solid-liquid separation tank; Dissolved ozone flotation tank to remove suspended matter and total phosphorus in the raw water treated in the first bioreactor; And a second bioreactor for microbial treatment of the raw water treated in the dissolved ozone flotation tank.;Such wastewater treatment apparatus has the advantage of combining the biological process and the chemical oxidation process using ozone to efficiently treat the sewage and wastewater containing hardly decomposable substances not treated only by the biological process.
