Gongye shui chuli, 1986 在工业废水中几乎都包括了不同浓度的有用成份,这些成份有的具有较高的经济价值应当加以回收,有的具有不同的毒性,会造成水体环境的严重污染,则应根据工业废水排放标准加以处理。所以,对工业废水的处理既希望对废水能进行有效的净化,又希望对废水中有价值的物质进行回收,而膜分离法在这方面显示出明显的优越性。目前,反渗透和超过滤的膜分离技术已在废水处理中得到了广泛的应用。本文就电镀废水、含油废水,化纤及印染废水、电泳漆装饰废水、造纸废水和放射性废水等利用膜分离的情况进行介绍。

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

Gongye shui chuli, 1986 工业废水排放造成水体污染和水资源的大量消耗,是目前国内外普遍关注的问题。而火电厂每天使用大量的水,并在运行中产生相当数量的废水,是一个水体的严重污染源和用水大户。火电厂的废水主要包括:冲灰(渣)水、化学废水、煤场排水、冷却塔排污、锅炉排污、除尘器清洗废水、空气预热器清洗废水和其它废水。废水的排放方式有连续排放和间歇排放两种,连续排放是正常运行中的排放水,它的水质相对比较稳定,间歇排放设备启动和检修时的排水, 其水量大小和水质变化都很大。

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT The covalent bonds at heterojunction interfaces enable more efficient charge carrier separation than traditional weakly coupled heterojunctions, with enhanced photocatalytic performance for organic wastewater purification. The interfacial covalent bonds drive energy band reorganization, rendering the conventional independent band edge ...

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...
