摘要：

The aim of this study was to investigate color, suspended solids (SS), chemical oxygen demand (COD) and biological oxygen demand (BOD) removal using modified sericite with magnesium (Mg-Sericite) flocculants in dyeing wastewater. Mg-Sericite flocculants successfully removed >95% of color, SS. COD and BOD in dyeing wastewater at the following optimal conditions: Mg-Sericite dosage of 40mg/L, pH of 11, Mg/Sericite ratio of 1.5, settling time of 20min, mixing time of 10min and mixing rate of 100rpm. The bioflocculant, Mg-Sericite, can be a promising flocculants due to its high efficiency and low dose requirements in dyeing wastewater treatment. In addition, Mg-Sericite does not contaminate treated wastewater, which can be recycled to reduce not only the cost and the demand for water but also the extra operational costs for reusing wastewater.
