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。

Public Administration, EarlyView.ABSTRACT As the public sector increasingly adopts AI‐powered automated decision systems (ADS), understanding how citizens experience and value ADS use in public decision‐making is both normatively and practically important. Therefore, we examine and compare the effects of seven attributes of public values on citizens' support for ADS adoption in two ...

Gongye shui chuli, 2022 含油清洗废水的深化处理及清洗剂回收再利用一直是工业废水处理领域关注的焦点。清洗剂具有既亲水又亲油的特点，其高效回收受到限制。同时，由于清洗废水所含油品种类复杂，很难匹配到合适的处理方法。为解决该难题，深入研究了过滤精度、跨膜压差、温度、浓度等因素对超滤膜法处理含油清洗废水及清洗剂回用效果的影响。研究结果表明，适宜过滤精度的膜元件、合适的跨膜压差和温度可实现较高的清洗剂回用率和石油类截留率。此外，废水中清洗剂的含量越高，产水中的清洗剂越多；石油类含量越高，清洗剂的回用率越低，膜受污染程度也越严重。结果表明，

World Food Policy, Volume 12, Issue 2, November 2026.ABSTRACT Household food expenditure continues to be a key factor in ensuring the realization of the Human Right to Adequate Food. Particularly in Brazil, access to food can be limited by economic constraints in vulnerable families, especially among farming families, who have been more vulnerable to food insecurity in recent years in the country.

Asian Politics &Policy, Volume 18, Issue 4, October 2026.ABSTRACT Indonesia's responses to Illegal, Unreported, and Unregulated Fishing (IUUF) shifted from assertive measures such as publicly bombing and sinking illegal ships to legal, educational, and cooperative measures. The changes in policies undertaken are puzzling, given that Indonesian policymakers' perception of IUUF has remained the same between ...
