Inoculated sludge from the Brewery wastewater treatment plant was cultured in a sequencing batch reactor (SBR). The granular sludge was then used to process the artificial simulation wastewater to compare the performance and efficiency of the granular sludge in organic matter removal by using SBR and granular membrane bioreactor (GMBR). Results showed that the granular sludge in the SBR exhibited desirable characteristics and good removal efficiency. The mixed liquor suspended solids (MLSS) and the sludge volume index (SVI) were approximately 2.56 g/L and 78.13 mL/g, respectively, and it exhibited a satisfactory settling ability. The removal efficiency of the resulting chemical oxygen demand (COD), NH3-N and total phosphorus (TP) reached 89.35%, 96.49% and 83.76%, respectively. The removal efficiency of both nitrate nitrogen and total nitrogen (TN) reached 90%. The performance of the granular sludge as well as the removal efficiency of the organic matter in the GMBR was subsequently observed. Results showed that the process influenced the characteristics and microbial biomass of the granular sludge. The SVI and the MLSS were about 175.82 mL/g and 1.14 g/L, respectively. The removal efficiency of COD and TP increased to 93.17% and 90.42%, respectively. The removal efficiency of NH3-N was slightly affected, whereas that of both nitrate nitrogen and TN increased to 95%. In this study, the physical properties and the removal efficiency of granular sludge in different bioreactors were compared. The comparison demonstrated that granulation membrane bioreactors perform more efficiently compared with SBR in wastewater treatment for organic matter removal.
接种了 brewery 废水处理厂的接种污泥在序批式反应器（SBR）中进行培养。然后使用颗粒污泥处理人工模拟废水，比较 SBR 和颗粒膜生物反应器（GMBR）中颗粒污泥对有机物去除的性能和效率。结果表明，SBR 中的颗粒污泥具有理想的特性和良好的去除效率。混合液悬浮固体（MLSS）和污泥体积指数（SVI）分别约为 2.56g/L 和 78.13mL/g，具有良好的沉降性能。COD、NH3-N 和总磷（TP）的去除率分别达到 89.35%、96.49%和 83.76%。硝酸盐氮和总氮（TN）的去除率均达到 90%。随后观察了 GMBR 中颗粒污泥的性能和有机物的去除效率。结果表明，该过程影响了颗粒污泥的特性和微生物生物量。SVI 和 MLSS 分别约为 175.82mL/g 和 1.14g/L。COD 和 TP 的去除率分别提高到 93.17%和 90.42%。NH3-N 的去除效率略有影响，而硝酸盐氮和 TN 的去除效率均提高到 95%。在本研究中，比较了不同生物反应器中颗粒污泥的物理性质和去除效率。比较表明，在有机废水处理中，与 SBR 相比，膜生物反应器具有更高的效率。
