  • 摘要: 高盐废水是目前水处理领域的难点,主要研究了不同因素下多孔铁碳合金填料对氯离子的去除效果,及Cl-的去除机理。在进水pH为2,停留时间为60 min,Cl-浓度20 000 mg/L条件下进行实验,通过静态实验和连续实验确定Cl-主要去除途径为微电解过程引起的填料吸附。这种合金填料对实际高氯废水也有较好的处理效果,针对变性淀粉废水,在最优条件下填料对废水中氯离子有较强的吸附去除能力,同时COD去除率能达到57%,废水的可生化性得以大幅度提高。
    Abstract: High salt wastewater, especially the high chlorine wastewater, is difficult to be treated. Chloride removal efficiency of porous iron carbon alloy filler in different factors and an in-depth research of Cl- removal mechanism were studied. The experiments were carried out under the conditions of initial pH of 2, reaction time of 60 min, Cl- concentration of 20 000 mg/L. It had found that the mainly removal pathway of Cl- was filler adsorption caused by micro electrolysis process through static and continuous experiments. Experiments showed that this alloy filler also had a good treatment effect on actual high chlorine wastewater. The filler had strong adsorption capacity on Cl- in modified starch wastewater under the optimal conditions. The removal rate of COD could reach 57% and the biodegradability of wastewater was greatly improved at the same time.
