摘要
采用Fenton高级氧化技术对猪场养殖废水进行了氧化处理,探讨了反应时间、pH值、温度、H2O2和FeSO4的投加量等因素对猪场养殖废水CODCr去除率的影响,确定了最佳的处理条件.试验结果表明,当〔H2O2〕=40 mmol/L,〔Fe2+〕=4mmol/L,pH=3.53,0℃条件下,反应40 min后,猪场养殖废水的CODCr的去除率达到最大值,为87.2%.
In this paper,the removal of CODc, of the swine wastewater by the Fenton process was investigated. The factors affecting swine wastewater removal efficiency, such as reaction time,pH value, temperature, content of H2O2 and Fe2＋ were systematically examined and the optimal conditions were found. The experiment shows that the maximum value of removal of CODcr reaches 87.2% in [ H202 ] = 40mmol/L, [ Fe2＋ ] = 4mmol/L, pH = 3.5,30℃ and 40 - minute reaction time.
