. Apparatus for treating wastewater using a rotating biological contactor with water mill wheels

摘要

The wastewater treatment apparatus of aberration type rotary biological contact type includes a tank and aberration type rotation mechanism, and the rotation mechanism is a plurality of plates fixed to the hub and the hub mounted on the rotation shaft to rotate together with the rotation shaft and the rotation shaft supported on the tank. Has a member. At least one wood fungus is attached to the plate members. By making a number of plate members made of wood, the plate members not only act as a natural carbon source for wood fungi, but also cause secondary metabolic reactions of wood fungi, resulting in the treatment of low concentrations as well as high concentrations of nitrogen-containing wastewater. Will be. By providing a light source means for irradiating visible light at regular intervals, it causes light stress on wood fungi and promotes metabolic reactions of wood fungi, thereby improving water treatment efficiency and performing high concentration nitrogen-containing wastewater treatment. do.
