三维电极法处理高浓度氨氮废水的试验研究

Experimental research on the treatment of high-concentration ammonia nitrogen wastewater by the three-dimensional electrode process

采用三维电极法处理高浓度氨氮废水,无需调节废水p H,控制电压14 V,加入200 g粒子颗粒电极,电解反应2 h,出水调节p H至9,过滤,出水NH3-N<15 mg/L,满足《污水综合排放标准》(GB 8978—1996)中的一级标准,为高浓度氨氮废水的处理探索了新途径,具有广阔的工业应用前景。

The three-dimensional electrode process has been used for treating high-concentration ammonia nitrogen wastewater. Without adjusting p H,by means of controlling the voltage at 14 V,adding 200 g of particle electrodes,reacting for 2 h,adjusting effluent p H to 9,and filtering,the effluent of NH3-N is less than 15 mg/L,which can meet the requirements specified in Level 1 of Integrated Wastewater Discharge Standard（GB 8978—1996）. A new way having broad industrial application prospect has been explored for the treatment of high-concentration ammonia nitrogen wastewater.
