A Trial Method on the Mixing Conditions in the Aeration Tank

In general, the mixing in the aeration tank have an effect on the efficency of this tank. Especially, in the last, the process of nitorogen removal in the aeration tank or in the deep aeration tank is a serious influenced by the mixing. However, research data on the mixing is insufficient, and there is only analysis by the complete mixing or the plug-flow models.
