Abstract
In order to address temporary treatment needs during the renovation of small–scale sewage treatment plants, a portable temporary wastewater treatment unit was developed and tested. This unit combines the “high performance coagulation sedimentation method” with the “single–tank MBR (membrane bioreactor)” and is suitable for use not only during renovations but also in disaster situations. Through practical experiments, the performance and application methods of the unit were verified, demonstrating its ability to adapt to variations in water temperature and BOD levels, ultimately achieving stable treated water. This technology is intended for deployment as an emergency recovery solution during both renovation periods and unforeseen events.
