Comparative Experiment Study on the Total Phosphorus Removal Efficiency of Different Infiltration Media Combinations in the CRI System

Abstract:

The total phosphorus removal efficiency is very low and the TP concentration of the effluent can not reach the national standard of GB18918-2002 in CRI system. In order to solve these problems, a series of comparative experiments on phosphorus adsorption capacity of 5 kinds of special infiltration media are carried out. And then another series of comparative experiments on the total phosphorus removal efficiency of 4 kinds of infiltration media combinations are also conducted, the experimental results show that the phosphorus adsorption capacity of sponge iron is the best one among the special infiltration media selected；the phosphorus removal efficiency of the infiltration media including 1/6 sponge iron is much better than the infiltration media including only sand; and the phosphorus removal efficiency of the infiltration media combination with sponge iron homogeneously mixed with sand, is better than the infiltration media combination with the same weight of sponge iron concentrated. The experimental results will help to explore the development of the new type composite infiltration media of the CRI System.
