| 摘 要： | 采用UV-Fe3+-Cu2+-H2O2体系对长沙黑糜峰垃圾填埋场经过生化法处理后的垃圾渗滤液进行了二次深度处理,发现体系在T为30~50℃,H2O2体积分数为0.12 mL/L,Fe3+浓度为0.2 mmol/L,Cu2+浓度为0.2 mmol/L,t为60 min条件下,废水COD从500~700 mg/L降至50~60 mg/L,色度从100倍降至无色,达国家一级排放标准。UV-Fe3+-Cu2+-H2O2体系对成分复杂且难降解的废水具有很好的处理效果,弥补了Fenton和UV-Fenton对pH值的要求过严和催化剂难回收的缺点。

| Abstract: | The paper carried out advanced treatment on the landfill leachate treated by biological and chemical means from the Heimifeng garbage landfill site in Changsha. It is found that when the system is on the condition that T = 30 - 50℃ ,H_2O_2 =0.12 mL/L,Fe~(3+)=0.2 mmol/L,Cu~(2+) = 0.2 mmol/L, t = 60 min, the COD of waste water falls from 500～700 mg/L to 50～60 mg/L, the colour falls from 100-fold to colourless, thus meeting the first level of the national discharge standard. UV-Fe~(3+) -Cu~(2+) -H_2O_2 system can treat the sewage difficult to dissolve with complexed components, overcoming the disadvantages that Fenton and UV-Fenton have a harsh demand on pH and the catalyst is difficult to recycle. |
