Gongye shui chuli, 2011 电镀清洗废水是电镀废水的一种,其成分复杂,毒性较大,直接排放会严重污染环境。若对电镀清洗废水处理后有效回用,可减少废水排放,节约水资源。依据工程实例,首次采用全膜法(UF-RO-EDI)处理电镀清洗废水,制备的高纯水(电阻率≥16.0 MΩ.cm)可直接回用于生产,废水回用率达到60%。介绍了这种回用系统的工艺流程及工程运行情况,该系统运行稳定,为电镀废水回用开辟了新的思路。

Gongye shui chuli, 2018 研究将处理后的火电厂生活污水，按照一定比例添加到脱硫工艺水中，并将其回用至脱硫系统。在中水回用过程中，以吸收塔浆液氯离子含量和石膏品质不变为导向，采用控制电导率的方式来确保回用水水质。2个月的试验跟踪分析结果表明，采用控制电导率的方法，可以将经处理后的火电厂生活污水成功回用至脱硫系统。同时，对中水回用方式进行了经济性分析，对存在的问题进行了探讨，并对下一步的研究提出了相应的建议。

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective
Policy Studies Journal, EarlyView.ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

Review of Policy Research, Volume 43, Issue 4, July 2026.ABSTRACT The accelerated digitalisation of society has amplified cybersecurity threats and revealed their cross‐sectoral nature. Yet, the policy instruments used to address these challenges remain insufficiently examined. This study conducts a scoping review of 980 academic articles (2007–2024) and applies Hood's NATO framework (Nodality, Authority ...
