Comparison of Two Types of Multi-soil-layering Treatment System Filled Different Paddings
2种不同模块化填料组合的多级土壤渗滤系统的比较

Two types of multi-soil-layering(MSL) systems,each of them was filled with different padding,including both the layers of mixture layers(ML) and permeable layers(PL),which designed for purifying polluted river water and for studying the difference of the pollutant removal efficiency between them under different operation conditions.The results indicated that the four systems all had great COD removal efficiency and the removal rate of each of them was above 50%.Zeolite-lightweight ceramic pellet system(Z-LC...
