Research Abstract

Domestic wastewater is treated by conventional activated sludge process. In this system, a mass of excess sludge is generated. The sludge has been treated through a variety of processes and has been reused or landfilled. In this study, the activated sludge process was performed under the high concentration of dissolved oxygen (DO) to suppress the growth of microorganisms for building up the treatment process with lower amount of excess sludge. Under the high concentration of dissolved oxygen, the growth rate was reduced without decrease in the removal rate of the substrate. And, the sedimentation properties are better than those in the conventional process. The genetic engineering analysis has confirmed that different microbial species were cultured under the high DO condition from those in the conventional process.
