Rare 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)

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 5, May 2026.ABSTRACT Layered double hydroxides (LDHs) are attractive non‐noble catalysts for overall water splitting (OWS), yet their hydrogen evolution reaction (HER) activity is often limited by suboptimal *H adsorption and a paucity of accessible sites. Herein, we introduce an oxygen‐vacancy (Ov) engineering strategy to construct ultrathin Ni‐Fe LDH nanosheets ...

Gongye shui chuli, 2015 秦皇岛某污水处理厂采用A2/O工艺进行污水处理, 设计出水满足《城镇污水处理厂污染物排放标准》(GB 18918-2002)的二级标准限值要求。由于对污水排放要求的提高, 该厂出水不能外排, 需进入中水厂进行深度处理。基于污水处理厂现状, 在分析工艺能耗构成的基础上, 通过合理确定污水处理程度, 调节风机风量分配, 对污水提升泵进行变频改造与优化运行, 达到了降低污水处理厂能耗的目的。
