Abstract:Abstract-The aim of this paper was to demonstrate the technical feasibility of AMD treatment using fly ash-doped porous concrete (FAPC). The FAPC were prepared through adding the fly ash into the ordinary porous concretes (PC), and the acid mine drainage (AMD) was treated by FAPC in this paper. The results show that: At influent pH of 2.9-3.4 and 24 h hydraulic retention time, the acidity of AMD was improved significant by FAPC, and which the pH of effluent was maintained at 8-9. The average removal rate of tu… Show more
