Gongye shui chuli, 2009 膜生物反应器(MBR)中膜污染具有阶段性发展特点。综合动态的“凝胶层黏附-泥饼层覆盖”理论以及 静态的膜污染层结构理论，认为以“污染层构建-临界通量打破”来描述MBR 的二阶段污染特征能够较好地反映其 形成内因。根据跨膜压力(TMP)与膜污染发展趋势的内在联系和特点，建立了“污染层构建”阶段的周期模型。并结 合MBR 处理市政废水的试验，就运行操作条件对“污染层构建”阶段周期的影响进行了正交水平分析。结果表明，各 试验阶段的“污染层构建”周期为5~12 d，适时地采用恰当的清洗措施非常必要 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Arsenic presents a critical duality as both a hazardous environmental pollutant and an indispensable material for advanced semiconductor technologies. This study proposes an integrated reductive vacuum sublimation strategy, assisted by carbon and lead additives, to purify crude arsenic containing high oxygen (7.4%) and antimony (1326 mg kg−1).
