摘要

    摘要
  • 摘要: 提出了一种膜过滤耦合电化学非均相沉淀的新型磷回收工艺对含磷废水进行处理,探究不同膜通量、电流密度、磷初始浓度及极性反转时间对磷去除和回收的影响。结果表明:在磷初始浓度为5 mmol/L、膜通量为22.1 L/(m2·h)和电流密度为20 A/m2的条件下,磷平均去除率为92.0%,产物的主要成分为鸟粪石。在flow-through操作模式下,不同磷初始浓度对磷去除效果无明显影响。当系统连续流运行时,每隔4 h极性反转6 min可使反应器磷去除与回收性能处于相对较优水平,磷去除率维持在90%左右。
    Abstract: A novel phosphorus recovery process combining membrane filtration and electrochemical struvite precipitation was proposed to treat phosphorus-containing wastewater. The effects of membrane flux, current density, initial phosphorus concentration and polarity reversal time on phosphorus removal and recovery were investigated. The results showed that the average phosphorus removal efficiency was 92.0% at an initial phosphorus concentration of 5 mmol/L, a membrane flux of 22.1 L/(m2·h) and a current density of 20 A/m2, and struvite was the dominant composition of the recovered products. In the flow-through operation mode, different initial phosphorus concentrations had no significant effect on phosphorus removal. When the system was operated in continuous flow mode, the phosphones removal rate was maintained at 90% by 6 min polarity reversal every 4 h operation.
