Abstract: The effect of electrochemical treatment for fosfomycin sodium pharmaceutical wastewater using RuO2/Ti as anode was investigated. The influences of temperature, NaCl concentration, initial pH and electric current on the degradation of CODCr and organic phosphorus were studied in details. The results showed that under the conditions of reaction temperature 80 ℃, concentration of NaCl 0.2 mol/L, initial pH 3.42 and electric current 4.0 A, the concentration of CODCr and organic phosphorus could degrade from 12 086 and 1 375 mg/L to 4 278 and 502 mg/L, with the removal rates of CODCr and organic phosphorus being over 64.7% and 63.5%, respectively. The biodegradability of wastewater was improved significantly with the BOD5/CODCr ratio increasing from 0.19 to 0.34.
