三槽式氧化沟污水处理工艺研究

Investigation on treatment process of watstwater by triple oxidation ditch

三槽式氧化沟是在传统的氧化沟基础上进行了一定改进和发展起来的工艺,具有流程较简单、能连续处理污水而不需设置二沉池,建筑物少,管理简单占地少等优点。作者分析研究了三槽式氧化沟工艺对城市生活污水中COD、悬浮物(SS)、NH3—N的处理效果,探讨了不同操作参数,包括进水中污染物浓度、溶解氧(DO)、pH值、操作温度等对处理效果的影响,与传统的氧化沟技术进行比较,三槽式氧化沟工艺具有较高废水处理效率。

Triple oxidation ditch process was improved based on traditional oxidation ditch technology and had some advantages of the simple treatment process,continueous treatment of wastewater without setup of secondary sedimentation tank,with less building and simply management as well as less ground demand.The treatment of COD,SS and NH3—N from city sewage by triple oxidation ditch process was studied and analyzed in this paper.The effect of different operating parameters such as influent concentration of pollutants,dissolved oxygen,pH and temperature on treatment was explored.Compared with the traditional oxidation ditch technology,triple oxidation ditch process has higher efficiecny of wastewater treatment.
