Description

本発明の排水処理装置は、活性汚泥を含む排水が貯留される処理タンクと、前記排水に浸漬される濾過膜と、オゾンを含む空気であるオゾン化空気を、前記排水の内部にて前記濾過膜の下方で発生させる気体発生手段と、を備え、前記気体発生手段は、前記濾過膜が整列する方向に沿って長軸を有する管路であり、前記濾過膜どうしの間隙の下方に配置された前記管路の散気孔から発生した前記オゾン化空気が、前記濾過膜に付着した前記活性汚泥から成る汚泥層の表面に接触することを特徴とする。

The wastewater treatment apparatus of the present invention is a treatment tank in which wastewater containing activated sludge is stored, a filtration membrane immersed in the wastewater, and ozonized air that is air containing ozone, which is filtered inside the wastewater. Gas generating means for generating below the membrane, and the gas generating means is a pipe line having a long axis along the direction in which the filtration membranes are aligned, and is disposed below the gap between the filtration membranes. Further, the ozonized air generated from the air diffusion holes of the pipe line is in contact with the surface of the sludge layer made of the activated sludge adhering to the filtration membrane .
