Abstract
- The aim of this study was to implement central-composite design (CCD) and response surface methodology (RSM) to optimize the operational parameters for hybrid anaerobic baffled microbial reactor (HABMR) remedying mixed printing and dyeing wastewater (MPDW). The individual and interactive effects of three variables, hydraulic retention time (HRT), pH, sludge loading rate (SLR) on the COD and color removal rates were evaluated. In the area of HRT: 12.5–13.9 h, pH: 9.0–9.5 and SLR: 0.27–0.33 kgCOD/(kgMLVSS d), COD and color removal rates of HABMR exceeded 40% and 60%, simultaneously. The check experiment revealed that the amount of COD and color in the effluent could be decreased by 9.97% and 10.12% compared to the usual operating conditions, respectively. The results verified that the RSM was useful for optimizing the operational parameters of HABMR in treating MPDW.
