Simulation Study on Constructed Rapid Infiltration for Treatment of Surface Wastewater in Town
نویسندگان
چکیده
On the base of land disposal, the objective of this study was to use constructed rapid infiltration (Abbreviation: CRI) to improve slightly polluted surface water in town. The data indicated that the average removal rates of BOD5 and NH4 -N were 80% and 65% in summer, respectively. In winter, the removal rates of BOD5 decreased evidently with the lowering of water temperature, but the change of NH4 -N was not obvious with the lowering of water temperature. The average removal rate of NH4 -N was 60% in winter. The study results indicated that the constructed rapid infiltration system had better purification effect on the slightly polluted water. The system could still operate normally at low temperature in winter.

In this study, we report removal of Diclofenac (DCF) through heterogeneous Fenton process using Fe-ZSM-5 catalyst. The parent catalyst was prepared by hydrothermal technique. Fe species were introduced by wet impregnation. Characterization of the catalysts was carried out using XRD, FT-IR, FE-SEM, N2 adsorption-desorption, NH3-TPD, and acidimetric-alkalimetric titration. The bimetallic catalyst...
