Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 2, doi: 10.1007/s11783-017-0920-z

Abstract: Artificial composite soil treatment system with the high infiltration rate (1.394 m·d ) had a good removalThe removal mechanism of TMP and SMX was mainly sorption and was related with hydrogeochemical processThe column with more silty clay at high infiltration rate (1.394 m·d ) had removal rates of 80% to 90%Removal was strongly related to sorption.The results showed that the removal of SMX and TMP was related to hydrogeochemical processes.
