With urban sewage treatment and the matrix of rapid filtration system Research, through the establishment of laboratory simula-tion soil column, for each single matrix material to study the effect of sewage. The results show:peat:soil:slag:The zeolite:vermiculite=2:3:5:1:1 ,comprehensive decontamination optimal effect. When the hydraulic load increases with peat soil、slag、zeolite matrix material sys-tem for the main treatment effect and stability. System smal test on the 2nd box high substrate removal efficiency than the 1st.The 2nd box with 15%.The zeolite, the system is better than the 1st tank removal effect. Efficiency is improved by 10%to 15% and the processing ef-ficiency is stability.
