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 kg COD/(kg MLVSSd), 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.
本研究旨在采用中心复合设计（CCD）和响应面法（RSM）优化用于处理混合印花和染色废水（MPDW）的混合厌氧折流板微生物反应器（HABMR）的操作参数。评估了三个变量（水力停留时间（HRT）、pH 值和污泥负荷率（SLR））对 COD 和颜色去除率的单独和交互作用。在 HRT：12.5-13.9 h、pH：9.0-9.5 和 SLR：0.27-0.33 kg COD/（kg MLVSSd）的范围内，HABMR 的 COD 和颜色去除率均超过 40%和 60%。验证实验表明，与通常的运行条件相比，出水中的 COD 和颜色量分别减少了 9.97%和 10.12%。结果表明，RSM 可用于优化 HABMR 处理 MPDW 的操作参数。
