| 摘 要： | 用自制微孔扩散式接触反应器对Fe2 催化臭氧化预处理垃圾填埋场后期渗滤液进行了实验分析.结果表明,添加一定量的Fe2 ,对臭氧氧化渗滤液中的化学需氧量(CODC r)具有明显的催化作用.当臭氧流量为8.89 mg/m in、Fe2 添加量为10 mg/L,经90 m in处理后,模拟废水的生化需氧量/化学需氧量(BOD5/CODC r)可由初始的0.17提高至0.35,改善了废水的可生化性;同时,渗滤液的色度、浊度、腐殖酸和悬浮物(SS)也有较高的去除率.

| Abstract: | Fe~(2 ) /O_3 was taken to pretreat the landfill leachate in the later period in a microporous transfer contact reactor specially designed.The experimental results showed that Fe~(2 ) can markedly catalyze ozonation.After 90 min reaction with flux of O_3 8.89(mg/min) and additive quantity of Fe~(2 ) 10 mg/L,the value of BOD_5/COD_(Cr) of landfill leachate in the later period was improved from 0.17 to 0.35,which reflected that the biodegradability of landfill leachate had been improved evidently.At the same time,Fe~(2 ) /O_3 can effectually remove the chroma and turbidity and humic acid and SS of leachate. |
