Abstract:

In order to improve the efficiency of electrocoagulation of indigo wastewater, natural clay minerals were used as synergistic adsorbents to treat indigo dyeing wastewater through a combined process of electrocoagulation and adsorption. The effect of clay type on floc settlement rate and the change of Zeta potential were explored, and the flocculation effect was evaluated by the wastewater color, turbidity, decolorization rate and chemical oxygen demand removal rate. Based on the best minerals selected, the synergistic mechanism of clay minerals and electrocoagulation was further analyzed, combined with floc microscopic observation. The results showed that the addition of clay minerals can reduce the absolute value of the Zeta potential. The main flocculation mechanism of diatomaceous and electrocoagulation was net trapping and sweeping, and it also possessed certain charge neutralization and adsorption bridging effect. After the electrocoagulation reaction was finished, it only needed to add 1 g/L diatomaceous to react for 3 minutes to reduce the absolute value of Zeta potential to the lowest, which was 15.585 mV, and to increase the decolorization rate of wastewater to 94.08%.
