Gongye shui chuli, 2012 采用A2/O-MBR组合工艺处理高浓度有机废水, 结果表明, 系统对COD、NH3-N、SS的去除率分别达到97%、96.8%、95.3%。当系统污泥负荷为0.40～0.55 kg/(kg.d)时, COD去除率随污泥负荷升高而上升。当抽停时间分别为12、4 min时, 系统能保持膜过滤性能的稳定。膜过滤阻力随运行时间的增加呈线性增长, 在一定条件下, 膜过滤阻力随膜通量增加而明显增大, 膜通量为13.6 L/(m2·h)时的膜过滤阻力上升速率要远小于膜通量为22.1 L/(m2·h)时的情况。

Gongye shui chuli, 2015 实验对比分析了有无磁化预处理条件下纳滤膜的无机垢污染情况。研究结果发现,磁化预处理能够有效减缓膜比通量的衰减,低压冲洗后膜比通量恢复率可高达90%,而无磁化预处理的纳滤膜通量恢复率仅为68%。SEM分析发现,加上磁化预处理后,纳滤膜表面生成的CaCO3垢不再是致密的方解石,而是质地松软、易脱落的文石结构,这更有利于维持纳滤膜的稳定运行。

Gongye shui chuli, 2006 我国的水资源日益短缺。为缓解供水不足的紧张局面，可进行污水的深度处理回用。膜分离是一种有效的回用方法，但膜易受污染，导致通量下降。作者采用溶胶-凝胶法制备了耐污染性强的SiO2/聚砜复合膜，并对其进行了性能表征。SEM图像显示该膜具有双皮层不对称结构，膜内均匀分散有SiO2粒子，该粒子既能增强膜的强度，又能提高膜的耐污染能力。以自来水对该膜进行了水通量测试，测试表明所制膜水通量较高，在0.10 MPa下可达250~300 L/（m2·h）。

Gongye shui chuli膜蒸馏是一种逐渐兴起的热驱动膜技术，近年来在高盐废水的处理中受到了大量关注。然而，膜结垢是制约膜蒸馏工业化应用的瓶颈问题。通过向直接接触式膜蒸馏系统中引入脉冲流场来缓解硫酸钙结垢，分别探讨了脉冲时长与脉冲频率对抑制结垢效果的影响以及通量强化效果。结果表明，在脉冲时长为0.5 s，脉冲频率为5 min-1的最佳条件下，膜蒸馏通量在运行20 h后仍能达到初始通量的70%以上，并且通量强化比（FER）接近于1.3。实验结束后的膜表面形貌分析也表明，最佳脉冲条件下的膜表面结垢较少，仍能够清晰地观察到膜结构 ...
