三种新型电极处理含铵废水的研究

Basic Study of Electrochemical Treatment of Ammonium Nitrogen-Containing Wastewater Using Different Electrode

在用电解法处理废水时,电极材料是影响废水处理的重要因素。本研究以硼掺杂金刚石薄膜(BDD电极)、钛阳极(DSA电极)、PbO2/Ti电极为阳极,采用电解的方法对含铵根离子废水(包括含氯离子及不含氯离子两种)进行实验。实验数据表明BDD电极、DSA电极的处理效果优于PbO2/Ti电极.

Ammonium nitrogen(NH+4) is electrochemically decomposed using a boron-doped diamond anode and its NH+4-decomposing properties are investigated.Intensive studies have been done on the electrochemical decomposition of organic compounds using a diamond anode.In actual treatment of wastewater,however,removal of NH+4 from wastewater is also essential because environmental regulations are becoming tighter.In this paper,the NH+4-decomposing properties of a boron-doped diamond anode were compared with those of conventional anodes,a PbO2/Ti anode and a dimensionally stable anode(DSA).
