SBR是序批式活性污泥法的简称，又称间歇式活性污泥法，是一种间歇曝气方法来运行的活性污泥工艺。
相较于其他工艺差别只需在一个池体内凭证时间顺序酿成差别的反应阶段。
事情历程分为进水阶段、反应阶段、沉淀阶段、闭水阶段、待机阶段。
第一步：从进水最先抵达装备最大容积竣事。
第二步：反应时可凭证差别微生物的生长特点、污水的性子和要抵达处置惩罚效果，接纳非限制曝气、半限制曝气、和限制曝气方法运行，通过控制反应室中污水的消融氧抵达厌氧、缺氧、好氧反应情形，完成多种处置惩罚功效，不但可以抵达去除有机物的目的，并且可以取得脱氮和除磷的效果。
第三步：沉淀阶段，目的是举行固液疏散相当于二沉池沉淀时间通常设置为1—1.5小时，直至污泥絮体和上清液疏散
第四布：闭水阶段是从反应器中使用滗水器将上清液倾轧，一直排放到最低水位。
到下次进水最先为待机阶段，可在该阶段举行多余污泥排放。
该装备具备占地面积小、结构简朴、投资低、运行本钱低、脱氮除磷效果高等优点。
SBR is the abbreviation of sequential batch activated sludge method, also known as intermittent activated sludge method, which is an activated sludge process operated by intermittent aeration method.
Compared with other processes, it only takes one pool to change to different reaction stages in chronological order.
The work process is divided into water inlet stage, reaction stage, precipitation stage, closed water stage and standby stage.
Step 1: From the beginning of water intake to the end of the maximum volume of the equipment.
Step 2: According to the growth characteristics of different microorganisms, the nature of the sewage and the treatment effect to achieve, it can be operated by non-restricted aeration, semi-limited aeration, and limited aeration. By controlling the dissolved oxygen of the sewage in the reaction chamber, it can achieve anaerobic, hypoxia and aerobic reaction environment, and complete a variety of treatment functions. In order to achieve the purpose of removing organic matter, and the effect of nitrogen removal and phosphorus removal can be achieved.
Step 3: The purpose of the sedimentation stage is to carry out solid-liquid separation, which is equivalent to the precipitation time of the second sedimentation tank, which is usually set to 1-1.5 hours until the sludge floc and the supernatant are separated.
Fourth cloth: The closed water stage is to discharge the supernatant by using a decanter in the reactor until the lowest water level.
The next water intake is in the standby stage, and excess sludge can be discharged at this stage.
The equipment has the advantages of small footprint, simple structure, low investment, low operating cost, and high nitrogen and phosphorus removal effect.
