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 ...

Gongye shui chuli, 2006 以再造烟叶(造纸法)生产废水为研究对象，对生产中两种主要工艺废水及生产综合废水进行了多项水质分析。研究结果表明，生产线中提取浓缩段与抄造成型段排放的工艺废水具有不同的水质特性，而生产综合废水则表现为一种弱酸性、中高浓度有机废水特性，可生化性较好。根据废水的上述特性，设计了一种“混凝—生化—脱色”的三级废水处理工艺并应用于2000t/a再造烟叶生产试验基地的废水处理中，工程实施运行后效果良好，吨水处理成本低，治理后的废水排放可达到国家《污水综合排放标准》GB8978—1996一级标准 ...

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 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Deep eutectic solvents (DESs) have displayed a significant potential in green recycling of spent lithium‐ion batteries (LIBs) cathode materials. In this study, we proposed a computational screening strategy based on the binding energy and hydrogen bonding performance via density functional theory and molecular dynamic calculation, achieving a ...

Gongye shui chuli, 2016 通过分析食品添加剂废水成分，探讨了现有混合废水处理工艺存在的问题，提出了在现有混合废水处理工艺前增设预处理工序的方案。对混合废水通过Fenton氧化、混凝沉淀等方法进行预处理后，现有污水处理工艺可以正常运行。工艺改造后的运行结果表明：经过预处理的混合废水再经原废水站处理后，出水水质能达到工业园区废水接管标准。由于混合废水得到综合利用，废水排放量也相应减少。

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT The electrocatalytic reduction of nitrate (NO3ER) has emerged as a promising strategy for mitigating NO3− ${{\text{NO}}_{3}}^{-}$ pollution in wastewater while concurrently producing value‐added ammonia; however, its process is significantly hindered by the lack of highly efficient and low‐cost electrocatalysts. Herein, we proposed several non‐

Gongye shui chuli, 2003 选择四种高浓度难降解有机废水,在2L高压间歇反应釜中,研究了湿式氧化效果与技术可行性。结果表明:从氧化的容易程度来看,乳化液废水>丙硫咪唑废水>甲胺磷废水>分散蓝废水;各废水湿式氧化后可生化性得到显著改善;Cu2+有不同程度的催化作用;甲胺磷废水和丙硫咪唑废水对不锈钢反应釜腐蚀严重,乳化液废水最适宜湿式氧化。反应温度显著影响废水湿式氧化效果,温度越高氧化率越高。

Gongye shui chuli, 2023 针对某精细化工企业生产废水的不同水质特点，将废水进行分类收集，根据不同处理需求，选择“蒸馏+隔油+Fenton氧化”工艺对高盐废水、树脂脱附废水进行预处理，选择“隔油+Fenton氧化”工艺对高浓废水、废气洗涤水进行预处理，预处理后废水再与其他低浓水按照一定比例复配，满足生化进水要求后，采用“水解酸化+两级A/O+混凝沉淀”工艺处理综合废水。该工艺不仅适合较复杂的水质处理，还适合应对波动性大的生产工况；预处理效果显著，综合出水可稳定达标。实际运行效果证明，综合废水COD、氨氮、总氮去除率分别达到85 ...

Political Ecologies of Storage for the 21st Century
Antipode, Volume 57, Issue 4, Page 1181-1193, July 2025.Abstract New resource storage arrangements are proliferating rapidly both in terms of physical infrastructures—for the storage of things like “clean” energy, nuclear waste, carbon dioxide, fresh water, and data—and as part of a set of discursive moves that reinforce a vision of a near future world in which problems of climate change mitigation and ...
