摘要：

采用三维电极法处理高浓度氨氮废水,无需调节废水pH,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pH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。

Abstract:

The three-dimensional electrode process has been used for treating high-concentration ammonia nitrogen wastewater. Without adjusting pH, by means of controlling the voltage at 14 V, adding 200 g of particle electrodes, reacting for 2 h, adjusting effluent pH 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.

Key words: three-dimensional electrode, high-concentration ammonia nitrogen wastewater, wastewater treatment
