DEVELOPMENT OF THE PORTABLE UNIT-TYPE WASTEWATER TREATMENT SYSTEM UNDER DISASTER

Abstract

 In this study, we confirmed the stable wastewater treatment capacity and effectiveness of the portable unit-type sewage treatment system under disaster conditions. This unit-type wastewater treatment system was constructed in a short period of 26 days. In addition, effluent water quality of this system for one year were less than 15 mg/L for BOD and less than 3000 CFU/mL for total coliform. Furthermore, the GHG emissions of this system were comparable to the conventional activated sludge process. These results suggest that the application of this system to the damaged wastewater treatment plant can quickly recover the water treatment function.
