【摘要】 研究了高铁酸钾滤液的稳定性,并以垃圾渗滤液为处理水样,考察了高铁酸钾滤液对水样中NH4+-N、COD、BOD5的处理效果。研究表明,100mL垃圾渗滤液中投加5mL浓度为21.45mmol/L的高铁酸钾滤液,对氨氮的去除率达到72%,COD去除率达到48%,BOD5去除率达到78%。更多还原

【Abstract】 As a new high efficient multi-functional water treating reagent, the potassium ferrate has many advantages, such as high efficient, non-toxic and non-hazardous. But its application is restricted by its instability. This stability of the potassium ferrate filtrate and the treatment efficiency of NH4+-N、COD、BOD5 of landfill leachate using the potassium ferrate filtrate were discussed. The experimental results showed that: When 5mL potassium ferrate whose concentration is 21.45mmol/L was added to 100 mL landfill leachate, the removal rate of ammonia nitrogen, COD, BOD5 could reach 80%, 46.5%, 70% respectively.更多还原
