Produced water contains high concentrations of total dissolved solids (TDS), metals, and organic matter. In areas of high water stress, beneficial reuse of produced water needs to be considered. This study evaluates the treatment capabilities, efficiency, and limitations of a sequencing batch reactor (SBR) to remove organic material and nutrients from produced water. SBRs have been used to facilitate biological organic and nutrient removal from municipal and industrial waste streams. Although the bacteria responsible for the treatment of municipal and most industrial wastewaters cannot tolerate the high TDS concentrations in produced water, the microorganisms native to produced water have the capacity to treat produced water. In a bench scale bioreactor test using produced water from the Denver-Julesburg Basin, the produced water was determined to be nutrient limited with respect to phosphorus. By adding a phosphorus supplement, soluble chemical oxygen demand (COD) removal was increased by over 20 % and ammonia removal increased by approximately 40 %. Various supplements, including KH₂PO₄, centrate from an anaerobic digester, and activated sludge from a municipal SBR, were added to the bioreactors to determine which of them was more effective. A pilot scale SBR followed by media filtration was used to evaluate the effects of operating conditions on produced water treatment. The hydraulic residence time ranged from 1.67 to 8.3 days during various phases of operation, with no measured effect on treatment performance. Adding 7.5 mg-P/L of KH₂PO₄ as a phosphorus supplement had the most significant effect on treatment performance of the system. The majority of COD removal switched locations from the filter columns to the bioreactors. Comparing total organic carbon to COD, the biologically available portion of COD appears to be treated in the SBR while recalcitrant carbon and inorganic material may need to be removed via physical or chemical methods.

采出水包含高浓度的总溶解固体（TDS），金属和有机物。在水压力高的地区，需要考虑对采出水进行有益的再利用。这项研究评估了排序批处理反应器（SBR）从产出水中去除有机物质和营养物的处理能力，效率和局限性。SBR已用于促进从市政和工业废物流中去除生物有机物和营养物。尽管负责处理市政和大多数工业废水的细菌不能耐受采出水中的高TDS浓度，但采出水本身的微生物具有处理采出水的能力。在台式生物反应器测试中，使用了丹佛-祖尔斯堡盆地的采出水，确定所生产的水相对于磷而言是营养受限的。通过添加磷补充剂，可溶性化学需氧量（COD）去除量增加了20％以上，氨气去除量增加了约40％。各种补品，包括KH_将2 PO ₄（来自厌氧消化池的浓缩液）和来自市政SBR的活性污泥添加到生物反应器中，以确定哪种更有效。使用中试规模SBR，然后进行介质过滤，以评估操作条件对采出水处理的影响。在不同的操作阶段中，水力停留时间为1.67到8.3天，对治疗效果没有明显影响。添加7.5 mg-P / L的KH ₂ PO ₄磷补充剂对系统的处理性能影响最大。大多数COD去除将位置从过滤柱切换到生物反应器。将总有机碳与化学需氧量进行比较，化学需氧量的可生物利用部分似乎已在SBR中进行了处理，而顽固性碳和无机物可能需要通过物理或化学方法去除。
