Gaps in humanitarian WASH response: perspectives from people affected by crises, practitioners, global responders, and the literature

open access: yesDisasters, Volume 47, Issue 3, Page 830-846, July 2023., 2023
Water, sanitation, and hygiene (WASH) interventions prevent and control disease in humanitarian response. To inform future funding and policy priorities, WASH ‘gaps’ were identified via 220 focus‐group discussions with people affected by crises and WASH practitioners, 246 global survey respondents, and 614 documents.

畜禽养殖废水处理工艺分析研究

open access: yesGongye shui chuli, 2021
随着人们对畜禽肉类需求的持续增加,畜禽养殖业迅猛发展,由此产生的畜禽养殖废水的污染问题日益严重。畜禽养殖废水中的有机物、氨氮、悬浮物等污染物浓度高,水质较为复杂,对人体健康和环境质量威胁较大。目前应用于畜禽养殖废水处理的工艺众多,不同组合工艺对养殖废水的处理效果不同。针对该类废水的水质特点,一般将物理、化学方法用于畜禽养殖废水的预处理及深度处理,主要采用生物法作为常规处理工艺。对适于处理畜禽养殖废水的好氧处理工艺、厌氧处理工艺进行了比较,分析了处理畜禽养殖废水的实际工程案例 ...

食品添加剂废水综合处理

open access: yesGongye 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。

某精细化工企业废水处理工程实例

open access: yesGongye 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 ...

Chloride Coordination‐Engineered Fe–NC Catalyst for Directed Singlet Oxygen Generation Through Peroxymonosulfate Activation

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Heteroatom coordination regulation is an effective strategy to enhance Fenton‐like catalysis of single atom catalysts, yet its impact on the local microenvironment of active sites still requires in‐depth investigation. Herein, Cl2–Fe–NC catalysts with axial Cl coordination are prepared.

Thermite‐Synthesized Fe–Ti–Al–Mg High‐Entropy Intermetallic Compound for Efficient Azo Dye Degradation

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

危废处置企业废水处理工程实例

open access: yesGongye shui chuli, 2020
针对某危废处置企业各车间产生废水的水质特点,分别对各车间废水进行预处理,再分类收集到废水站进行集中处理。其中高浓废水经Fenton预处理后,与其他废水在综合调节池内混匀,最终经水解酸化+接触氧化+MBR的生化处理工艺,使出水达标排放。工程运行结果表明,废水经分类处理及最终综合处理后,出水可达到地表水环境质量标准(GB 3838—2002)中的准Ⅴ类排放标准。其中COD平均为30.6 mg/L,NH3-N平均为1.28 mg/L,TP平均为0.32 mg/L。

Guanidinium‐Based Covalent Organic Frameworks via Pore Wall Regulation: Efficient Selective Palladium Recovery From Metallurgical Wastewater

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Recovering palladium (Pd) from low‐concentration metallurgical wastewater still poses significant challenges. In this study, triaminoguanidine hydrochloride was used as the key functional site, and three guanidine‐functionalized covalent organic frameworks (GCOFs) were successfully constructed by adjusting the substituents (–H, –OH, and –OCH3)

MVR蒸发技术在废水处理中的应用研究

open access: yesGongye shui chuli, 2023
随着环境污染和水资源短缺的加剧,对于工业废水的排放要求日趋严格,常规的废水处理技术已无法满足废水的处理要求,尤其是高含盐、高有机物、高毒性的难降解废水,其有效处理仍然是难点。为满足国内对高难度废水的处理要求,采用MVR蒸发技术,通过卧式降膜蒸发装置,分别对高盐废水、焦化废水RO浓缩液和垃圾渗滤液NF浓缩液进行中试处理。结果表明,该技术可对上述废水进行10~20倍的有效浓缩处理,减量化效果明显,且蒸馏水出水水质良好,可满足排放或回用的要求。废水处理产出1 t蒸馏水的最高电耗为25.1 kW·h,电价按0 ...
