摘要
利用担载型双金属活性组分催化剂 ,考察了反应温度、压力、进料空速和V(空气 )∶V(H2 O) (体积比 )等反应条件对催化湿式氧化处理某农药废水效果的影响。对于该种废水 ,在 4 .2MPa ,2 4 5℃ ,空速为 2 .0h-1,V(空气 )∶V(H2 O) =30 0的反应条件下 ,废水的COD去除率可达到 91.3%。经处理后废水的BOD5/COD >0 .5 ,说明其可生化性能良好。
The wastewater in pesticide plants on the supported bimetallic catalyst is treated and the operation conditions of CWO including temperature,pressure,space velocity and the ratio of air/water are investigated. It is found that the reduction of COD is 91.3% at 245 ℃,4.2 MPa,SV 2.0 h -1 and V (air)∶ V (water)=300. After CWO treatment,the ratio of the BOD 5/COD Cr of the wastewater is higher than 0.5 which exhibits good biodegradability.
