摘要
针对有机磷农药废水成分复杂、有机物浓度高、具有生物抑制性、可生化性差等特点,本文采用Fenton联合臭氧氧化进行了预处理试验研究。通过单因素试验确定了Fenton反应H2O2加量、n[Fe2+]/n[H2O2]、p H、反应时间及臭氧氧化时间等参数。整个预处理系统出水COD去除率达86.9%,总磷的去除率达82.2%,可生化性提高,为后续综合污水的生物处理提供了有利条件。
Because of the organophosphorus pesticide wastewater contained the characteristics of complex composition, high concentration of organic matter, biological inhibitory, poor biochemical, this paper introduced the pretreatment using Fenton-ozone oxidation experimental research. The Reaction conditions such as H2O2 addition quantity, n （Fe^2＋ ）/n （ H2O2 ）, pH, reaction time of Fenton and Ozone oxidation time were determined by the single factor experiment. The COD removal rate was 86.9%, and the total phosphorus removal rate was 82.2% of the pretreatment system,which can improve the biodegradability and provides favorable conditions for subsequent biological treatment of the comprehensive sewage.
