Abstract

Antibiotics can reach the aquatic environment through varwus sources such as antibiotic industry, hospital effluent and excretion from humans and livestock. The removal of antibiotics from wastewater has not been effective due to their relatively low concentrations and because the conventional wastewater treatment plant (WTP) is not designed to remove them. The problem associated with the presence of antibiotics in low concentrations in the environment is the development of antibiotic resistant bacteria which could lead to severe health problem. The study examined the effectiveness of modified photo-Fenton treatment of an antibiotic wastewater containing amoxicillin and cloxacillin and determined the optimum operating conditions (H20 2/COD molar ratio 2.75, Hz0z/Fe3+ molar ratio 75, HzOz/CzHz04 molar ratio 37.5, irradiation time 90 min and pH 3) of the treatment. A series of experiments modeled by the RSM software were conducted to obtain the optimum operating conditions. Then, under the optimum operating conditions, efficiency of modified photo-Fen ton treatment of the antibiotic wastewater was tested. The efficiency and optimum operating conditions of the modified photo-Fenton treatment were then compared to the efficiency and optimum operating conditions of Fenton and photo-Fenton treatments. The study has found that the biodegradability improved from -0 to 0.35 in 90 min, and the COD, NH3-N and TOC removal were 78.85%, 46.85% and 52.30%, respectively.
