摘要
以RuO2/Ti为阳极,研究了电化学方法对磷霉素钠制药废水的处理效果,探讨了反应温度,NaCl浓度,初始pH和电流等因素对处理效果的影响。结果表明:当反应温度为80℃,NaCl浓度为0.2mol/L,初始pH为3.42,电流为4.0A时,反应180min后,CODCr和有机磷浓度分别由12086和1375mg/L降至4278和502mg/L,去除率分别达64.7%和63.5%,BOD5/CODCr由0.19升高到0.34,可生化性明显提高。
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.
