臭氧催化氧化技术在垃圾渗滤液深度处理中的应用研究

Application of ozone catalytic oxidation in advanced treatment of landfill leachate

本文研究了臭氧氧化及不同催化剂作用下臭氧氧化对垃圾渗滤液生化出水中COD的去除效果,结果表明:臭氧氧化可有效去除垃圾渗滤液生化出水中COD,臭氧投加量为8.33mg/(L·min),氧化2h的COD去除率在50%~60%之间,氧化时间为4h时可使COD达出水标准,但成本较高;使用C颗粒做催化剂,同样试验条件下COD去除效率可达到65%~70%之间,反应效率明显提升。

The removal of COD from biochemical effluent of landfill leachate by ozonation and ozonation with different catalysts was studied. The results show that ozonation can effectively remove COD from biochemical effluent of landfill leachate.The dosage of ozone is 8.33mg/(L.min). The removal rate of COD in two hours of oxidation is between 50% and 60%. When the oxidation time is 4 hours, COD can reach the effluent standard, but the cost is high..Using C particles as catalyst, the COD removal efficiency can reach 65%~ 70% under the same experimental conditions, and the reaction efficiency can be significantly improved.
