The existence of three-phase separator did not affect COD removal in the EAnCMBR. The existence of three-phase separator aggravated methane leakage of EAnCMBR. The existence of three-phase separator aggravated membrane fouling rate of EAnCMBR. Start-up of EAnCMBR equipped three-phase separator was slightly delayed.

在中空纤维载体内表面沉积分离层制备中空纤维复合内膜为其工业应用提供更多机遇,然而目前仍面临诸多挑战。本文提出通过涂覆/错流法在单通道或多通道陶瓷中空纤维内表面制备聚二甲基硅氧烷(PDMS)复合膜。通过控制聚合物浓度和涂覆时间,优化了PDMS/陶瓷中空纤维复合内膜的纳米结构和分离性能。分别用场发射电镜(FE-SEM)、傅里叶红外光谱(ATR-FTIR)、纳米压痕/划痕技术和渗透气化回收生物丁醇测试表征了膜的形貌、表面化学性质、界面结合力和分离性能。系统研究了陶瓷中空纤维内表面PDMS膜层的形成机理。优化的PDMS/陶瓷中空纤维复合内膜具有薄且无缺陷的分离层,用于60 ℃下1 wt%正丁醇-水混合物分离,通量高达约1800 g·m–2·h–1,分离因子为35~38。本文提出涂覆/错流的简便方法用于制备中空纤维内表面涂层,显现出巨大潜力,在膜材料、吸附剂、复合材料等领域具有广泛应用前景。

As the demand for high-performance bearings gradually increases, ceramic balls with excellent properties, such as high accuracy, high reliability, and high chemical durability used, are extensively used for high-performance bearings. In this study, a spiral V-groove plate method is employed in processing high-precision ceramic balls. After the kinematic analysis of the ball-spin angle and enveloped lapping trajectories, an experimental rig is constructed and experiments are conducted to confirm the feasibility of this method. Kinematic analysis results indicate that the method not only allows for the control of the ball-spin angle but also uniformly distributes the enveloped lapping trajectories over the entire ball surface. Experimental results demonstrate that the novel spiral V-groove plate method performs better than the conventional concentric V-groove plate method in terms of roundness, surface roughness, diameter difference, and diameter decrease rate. Ceramic balls with a G3-level accuracy are achieved, and their typical roundness, minimum surface roughness, and diameter difference are 0.05, 0.0045, and 0.105 mm, respectively. These findings confirm that the proposed method can be applied to high-accuracy and high-consistency ceramic ball processing.
