Abstract
This study was focused on removal efficiency of complex (or mixed) wastewater from agricultural and industrial plant for advanced treatments by HBR-II process, that was well known to be suitable to the treatment of livestock wastewater. The main purpose of this study was intended to evaluate the applicable feasibility of the HBR-II for revamping the present activated sludge process to the advanced one. And also, the settling study including the batch typed experimental column tests was performed to evaluate the coagulation stability of organic colloidal particles in wastewater. The mid-scale plant of HBR-II process between pilot and laboratory was used for this study. As F/M ratio remains constant in the range of 0.20~0.25 $BOD_5/Kg{\cdot}MLSS/Day$, the efficiency of biological treatment increased. It has been shown that the results of biodegradation study were, for removal efficiency(%), $BOD_5$ 98.4%, $COD_{Mn}$ 92.9%, SS 97.5%, T-N 91.3%, T-P 82.3%, respectively, which were relatively higher than other processes. From this study, HBR-II process would be well applied to the biological treatment of agricultural and industrial complex wastewater.
