Electrochemical treatment of the anaerobic digestion effluents using a Ti/Pt-IrO(2) electrode was evaluated in this study. The effects of electric current, NaCl dosage, and initial pH on ammonia, nitrate, total organic carbon (TOC), inorganic carbon (IC), final pH, and turbidity variations were studied in a series of batch experiments. It was found that the electric current and NaCl dosage had a considerably larger effect on the oxidization of ammonia; this was less for the effect of the initial pH. In addition, electroflotation was the main mechanism for turbidity, TOC, and IC removals. Further, the IC removal was mainly affected by the pH of wastewater. The electrochemical treatment using Ti/Pt-IrO(2) electrode without pretreatment was feasible for the anaerobic digestion effluent.
本研究评估了使用Ti/Pt-IrO(2)电极对厌氧消化废水进行电化学处理的效果。在一系列间歇实验中，研究了电流、NaCl用量和初始pH对氨、硝酸盐、总有机碳（TOC）、无机碳（IC）、最终pH和浊度变化的影响。结果发现，电流和NaCl用量对氨的氧化影响较大，而初始pH的影响较小。此外，电浮选是去除浊度、TOC和IC的主要机制。此外，IC的去除主要受废水pH的影响。使用Ti/Pt-IrO(2)电极在不进行预处理的情况下对厌氧消化废水进行电化学处理是可行的。
