Abstract

Surplus sludge produced by sewage treatment plants is one of the important repositories of antibiotic. In order to reduce the adverse effect of the antibiotics on the environment, the sludge drying reed bed was used to treat the sludge. The experiment investigated the removal efficiency of antibiotics in the process of sludge stabilization by the dry bed with ventilation structure and the sludge drying reed bed with and without ventilation structure. The research project spent four years, including three years loading period and one year natural stabilization period. In this paper, the degradation of target antibiotics (roxithromycin, azithromycin and oxytetracycline) during the natural sludge stabilization period was studied, the effects of different conditions on the removal efficiency of antibiotic were analyzed. The results show that the sludge drying reed bed can effectively remove roxithromycin, azithromycin and oxytetracycline in the sludge, the reed and ventilation structure plays an obvious role for promoting antibiotics removal in the system.
