Wastewater treatment equipment and wastewater treatment method for wastewater containing high-concentration organic matter

摘要

PROBLEM TO BE SOLVED: To treat high TOC wastewater AH with a high volumetric load, stabilize the treatment for decomposing organic carbon, and improve the treatment capacity. SOLUTION: The activated sludge (B2) after anaerobic treatment is provided with an aerobic treatment tank (2) for aerobic treatment of low TOC wastewater and an anaerobic treatment tank (3) for anaerobic treatment of high TOC wastewater. Is recirculated in an aerobic treatment tank (2), and a wastewater treatment facility equipped with an ORP measuring device (5) and an MLSS measuring device (6) in front of the anaerobic treatment tank (3).
