The performance and enhancement of pollutants removal in raw municipal sewage by a new pretreatment process were investigated in this study. The experiments were carried out with a GS sedimentation tank in full scale plant. The results revealed that average removal efficiency of TP, TSS, and TN achieved 49%, 67.3% and 20% respectively during stable running period. TSS removal rate could achieve about...
The pilot plant study comprised the sequencing batch reactor (SBR) operational mode of a contact oxidation filtration separation integrated bioreactor (CFBR) for treating municipal wastewater. The CFBR was made up of an upper biofilm reactor and a lower gravitational filtration bed. Polyacrylonitrile balls (50mm diameter, 237 m2/m3 specific surface, 90% porosity, and 50.2% packing rate) were filled...
Effluent of wastewater treatment plant is to be disinfected to protect drinking water sources. DOF(dissolved ozone flotation) was developed to meet this purpose. A DOF is strengthened system with ozone to a DAF(dissolved air flotation) system. A DAF system has good floating power by numerous micro-bubbles, and ozone has strong oxidation capability. And DOF system has good floating power and strong...
