焦化废水是煤焦化过程产生的废水,含有高浓度的酚类、苯系物、杂环化合物、多环化合物等有机污染物,并且高盐、高氨氮,是一类难处理的工业废水。随着国家对焦化废水的管理日趋严格,传统的“预处理+生化处理”工艺很难满足排放或回用要求,因此对焦化废水的深度处理势在必行。从物化法和生化法两个方面对目前焦化废水深度处理常用技术的研究和应用情况进行了介绍,并探索性地提出了焦化废水深度处理技术未来的研究和发展方向。

微生物燃料电池(MFCs)能够在降解有机物的同时将化学能转化为电能,近年来其独特的能源环境效应在降解藻类生物质方面引起广泛关注。然而,成分复杂的藻类细胞壁会阻碍藻类生物质在微生物燃料电池中的降解。为了提高微生物燃料电池降解藻类生物质的效能,通常需要对藻类生物质进行预处理,破坏藻类细胞壁使生物基质释放,并将难降解的大分子有机物分解为易降解的小分子有机物。综述了目前应用于微生物燃料电池降解藻类生物质的预处理方法,包括机械法、加热法、微波法和超声波法等物理预处理法,酸、碱、氧化等化学预处理法,酶或微生物细胞 ...

Differences in characteristics between naturalized threatened plants and other threatened plants
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.
