Waste water treatment basin sub-divided by blocks for simultaneous nitrification and de-nitrification without mixer assemblies

摘要

An aerobic water treatment system consists of an elongated basin which is sub-divided by a series of blocks. An aerobic water treatment system consists of an elongated basin sub-divided by a series of blocks, each separated from the next by a vertical slit. Water flows from an inlet at one end of the basin to the other where it is discharged. The blocks are raised above the bed of the basin and there are no gaps between the blocks and basin walls. An air inlet releases air underneath the gap separating each block from the next.
