چکیده انگلیسی
The study examined the effect of operating conditions of the Fenton process on biodegradability improvement and mineralization of amoxicillin, ampicillin and cloxacillin antibiotics in aqueous solution. In addition, degradation of amoxicillin, ampicillin and cloxacillin under optimum operating conditions were evaluated. The optimum operating conditions for an aqueous solution containing 104, 105 and 103Â mg/L amoxicillin, ampicillin, and cloxacillin, respectively were observed to be COD/H2O2/Fe2+ molar ratio 1:3:0.30 and pH 3. Under optimum operating conditions, complete degradation of amoxicillin, ampicillin and cloxacillin occurred in 2Â min. In addition, biodegradability improved from â¼0 to 0.37 in 10Â min, and COD and DOC degradation were 81.4% and 54.3%, respectively in 60Â min. Maximum biodegradability (BOD5/COD ratio) improvement was achieved in 10, 20 and 40Â min at antibiotics concentration 100, 250 and 500Â mg/L, respectively for each antibiotic in aqueous solution. Increase in nitrate and ammonia concentration were observed due to mineralization of organic nitrogen, concentration of nitrate increased from 0.3 to 10Â mg/L and concentration of ammonia increased from 8 to 13Â mg/L in 60Â min. The study indicated that Fenton process can be used for pretreatment of amoxicillin, ampicillin and cloxacillin wastewater for biological treatment.
