序批反应器技术用于油田矿区污水处理

Sequencing Batch Reactor Technology Used for Oilfield Sewage Treatment in Mining Area

在油田矿区、作业区应用序批式反应器(SequencingBatchReactor-SBR)技术处理生活污水较为普遍。针对现阶段SBR在设计过程中需要重点关注的问题如对部分污染物的去除受限制、需配置反硝化工艺、碳源的选择等进行分析。SBR是一种半连续形式的污水处理系统,该系统中污水的水质和水量调节、污染物降解、固液分离都在一个空间内完成。它具有系统紧凑、时控性高、所有处理工序按先后在一个反应器中完成的特点。因此SBR处理系统非常适用于非连续来水且水量低的小型污水处理厂。SBR是以时控为技术措施的活性污泥法,具有活性污泥法的一切优点,并具有流量调节和固液分离的功能,可解决小型污水厂固液分离单元选型难的问题,对污染治理效果显著。因此,有必要对SBR技术加以深入分析,推动其更好地进行工程应用。

SBR technology is widely used in the treatment of sewage in oilfields,mining areas and operation areas.This article focuses on analyzing the issues that need to be paid attention to in the design process of SBR at this stage,such as the removal limitation of some pollutants,the configuration of de-nitrification process,and the selection of carbon sources.Sequencing Batch Reactor(SBR)sewage treatment system is a semi-continuous sewage treatment system.In this system,sewage water quality and quantity adjustment,pollutant degradation,and solid-liquid separation are all completed in one space.It has the characteristics of compact system,high time control and all processing procedures are completed in one reactor in sequence.Therefore,the SBR treatment system is very suitable for small sewage treatment plants with discontinuous incoming water and low water volume.In essence,SBR is an activated sludge method with time control as a technical measure.It has all the advantages of activated sludge method.In addition,it also has the functions of flow adjustment and solid-liquid separation,which solves the problem of difficult selection of solid-liquid separation units in small sewage plants,its effect on pollution control is remarkable.So it is necessary to conduct an in-depth analysis of SBR tech-nology to promote better engineering applications of this technology.
