摘要
本文研究了复合高铁酸盐对焦化废水中氨氮的去除作用及不同环境因素对氨氮脱除的影响 ,实验结果表明 ,当溶液中高铁酸根浓度为 6 0 .1 4mg/L,温度为 71℃时 ,焦化废水原始水样中的NH3- N浓度可由 3 4 93 .8mg/L降至 1 6 5 3 .9mg/L,氨氮脱除率约为 5 6 % ;对于经生化处理后的氨氮浓度为 2 .70 6 mg/L的焦化废水 ,当溶液中高铁酸根浓度为 1 3 .2 78mg/L,NH3- N浓度可降至 0 .0 3 4 5 mg/L,N去除率达 98.7%以上 。
The removal efficiency of the ammonia-nitrogen in cocking wastewater by compound ferrate was studied. The effects of the FeO 2-_4 concentration, pH and temperature in the removal of NH_3-N were investigated. The results were suggested that the NH_3-N in the crude cocking wastewater could be removed from 3493.8mg/L to 1653.9mg/L when the ferrate concentration was 60.14mg/L and the temperature was 71℃; while in the disposed cocking wastewater, the NH_3-N concentrtration was decreased from 2.706mg/L to 0.0345mg/L when the ferrate concentration was 13.278mg/L, and the removal rate reached 98.7%.
