硅藻土对填埋场膜滤浓缩液吸附处理效果研究
|
摘要
探究了硅藻土对填埋场纳滤膜滤浓缩液吸附处理效果,分析了硅藻土投加量、吸附时间及pH对其盐度、电导率和COD去除效率的影响。结果表明,当pH=7、硅藻土投加量为25 g/L、吸附时间为50 min时,膜浓缩液水质有所改善,其COD去除率约为15.37%,其中的盐、腐殖质基本不会被硅藻土吸附而去除,所去除的COD主要来自易降解有机物。
The adsorption treatment effect of the nanofiltration membrane concentrated leachate from landfill site by diatomite was investigated. The effect of diatomite dosage, adsorption time and pH on the removal of salinity, conductivity and COD were discussed. The results showed that the water quality of concentrated leachate was improved at the optimal conditions when p H, diatomite dosage and COD removal rate were 7, 25 g/L, and 50 min, respectively.The highest COD removal rate was 15.37% which could be ascribed to easily degradable organics. However, the salinity and humics of concentrated leachate could not be removed by diatomite adsorption.
