This study presents the design, development, and demonstration of a pilot-scale Up-flow Floating Surface Constructed Wetland (UFSCW) for municipal wastewater treatment. UFSCW integrates primary and secondary treatments in a compact system. The UFSCW operates on the principle of up-flow movement of wastewater, through a floating arrangement of media and wetland plants. It provides a reduction in the velocity of suspended solids and increase contact time between pollutants, microbial communities, and plant root zones. The system combines both suspended and attached growth processes with anaerobic and aerobic treatment in a single unit. The system was operated in three phases: without hanging media and wetland plants, with hanging media only, and with both hanging media and wetland plants, under varying HRTs (36 to 12 h). At an HRT of 24 h (Phase III), UFSCW achieved maximum removal efficiencies of TSS, COD, TN, and TP of 92%, 82%, 67%, and 71%, respectively. Among the evaluated plant species, vetiver grass <em>(Chrysopogon zizanioides)</em> demonstrated the highest nutrient uptake efficiency. Its deep and fibrous root network provided an extensive rhizosphere that supported microbial colonization and facilitated enhanced nitrogen and phosphorus removal. Compared to conventional constructed wetlands requiring 2–4 days HRT, the UFSCW achieved comparable organic and nutrient removal at significantly shorter retention times, demonstrating its suitability for decentralized and space-constrained urban applications. Furthermore, integration of a downstream planted substrate bed and a disinfection unit could enable consistent compliance with discharge standards and facilitate treated water reuse.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"407 ","pages":"Article 129856"},"PeriodicalIF":8.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147832025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposed a multi-scalar analytical framework to systematically assess the current applications and future directions of social media in flood-related research. We adopted a semi-automated method supported by large language models, combining the PRISMA protocol with KeyBERT for keyword extraction, and analyzed 105 relevant publications. The framework covered four spatial levels: global, regional, urban, and community, and integrated extracted insights using GPT-4o. Results showed that: (1) the global and national scales emphasized cross-platform disaster identification and policy feedback mechanisms; (2) the regional scale highlighted variations in risk perception and interregional information coordination; (3) the urban scale focused on real-time monitoring and fine-grained spatial modeling; and (4) the community scale concentrated on individual evacuation behavior and neighborhood network analysis. Social media data demonstrated strong timeliness, high public engagement, and significant complementarity with traditional data sources in flood research. Nevertheless, key challenges remained, including limited cross-linguistic and cultural modeling capabilities and insufficient mechanisms for multi-source data integration.

Servitization—the integration of services into manufacturing—has been suggested as a business model that could support more sustainable production by increasing resource efficiency and generating value throughout the product's lifecycle. However, there is limited empirical evidence on what drives servitization and its effects on sustainability, especially concerning the role of digitalization and its varied impacts on environmental and social management practices. This study aims to explore how digitalization influences servitization and, in turn, how servitization affects environmental and social management practices. Using data from Spanish manufacturing companies in the 2022 Spanish Survey on Business Strategies, an inverse probability-weighted regression adjustment (IPWRA) estimator corrects for selection bias in servitization decisions. This method was applied to 1469 manufacturing firms, enabling reliable comparisons between servitized and non-servitized companies. The findings reveal that digitalization significantly raises the likelihood of adopting servitization, indicating that digital capabilities are a key enabler of service-oriented business models in manufacturing. Moreover, servitization is positively linked to several environmental management practices, including recycling and reuse of materials, reduced natural resource consumption, and energy savings or shifts toward more sustainable energy sources. However, no statistically significant connection is observed between servitization and companies' social management practices. These results indicate that although servitization offers tangible environmental benefits, its social advantages may take longer to emerge, require additional organizational adjustments, or involve higher service levels. Overall, servitization enhances environmental efficiency but does not automatically lead to improvements in social management practices.</div></div>","PeriodicalId":356,"journal":{"name":"Journal of Environmental Management","volume":"407 ","pages":"Article 129814"},"PeriodicalIF":8.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147807397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the great prospect of microbial inoculants for improving soil fertility and plant growth, it remains poorly understood whether and how microbial inoculants can amplify the effects of organic fertilizers on soil microbial community structures and tea yields. Here, we conducted a field experiment in tea plantations of Rougui and Shuixian cultivars, where the control group only applied organic fertilizer, and the treatment group used a mixed fertilizer (microbial inoculant and organic fertilizer). After four months of fertilization, soil organic matter, total nitrogen, total phosphorus, and alkali-hydrolyzable nitrogen contents were higher in the Rougui tea plantation applied with mixed fertilizer than in the control, whereas these soil nutrients were lower in the Shuixian tea plantation with mixed fertilizer than in the control. PCoA revealed significant separations of soil bacterial and fungal communities between the Rougui and Shuixian tea plantations, and different fertilization regimes in the Rougui tea plantations (<em>p</em> = 0.001). The addition of microbial inoculants enhanced the stochastic assembly processes of both soil bacterial and fungal communities, with the normalized stochasticity ratio of bacterial communities increased by 42.86% one month after the fertilization (<em>p</em> ≤ 0.0001), and that of fungal communities increased by 79.40% after six months (<em>p</em> ≤ 0.0001).

Importantly, the mixed fertilizer increased the yields of fresh teas of Rougui and Shuixian by 83.61% and 11.81%, respectively, compared with the application of organic fertilizer alone, a pattern consistent with elevated stochastic processes and network complexity in soil microbial communities.
