Abstract:

To comprehensively analyze and summarize the current status of research on wastewater treatment technologies in aquaculture, bibliometric methods were employed to screen and organize relevant literature from CNKI and the Web of Science(WoS) Core Collection databases in the past ten years. A total of 1 043 and 233 valid literature samples were obtained from CNKI and WoS, respectively. The literature samples were visualized and analyzed by CiteSpace and VOSviewer software, focusing on aspects such as publication year, country, authors, research institutions, and keywords. The results indicated that research conducted in China holded a dominant position in the field of aquaculture wastewater treatment technology, with research activity far surpassing that of other countries. The core disciplines involved in research in this field both domestically and internationally were primarily environmental sciences, although contributions from agriculture, engineering, biological, and chemical disciplines also played significant roles in the development of this field. This interdisciplinary nature fostered the updating and innovation of treatment technologies and helped to deal with complex pollutants. However, a close global network of cooperation had not yet been formed in this field. Nevertheless, there was considerable potential for inter-institutional collaboration in the future. Over the past decade, research in this field had shifted towards novel treatment approaches that were highly efficient and minimized secondary pollution. There had been an expansion in the types of pollutants effectively treated, and a greater emphasis had been placed on sustainability, resource and energy recovery.

Key words: bibliometrics, visual analysis, farming, wastewater treatment technology

摘要：

为全面分析并总结养殖业废水处理技术研究的现状，利用文献计量学方法，对近10 a来CNKI和Web of Science（WoS）核心合集数据库中与养殖业废水处理技术相关的文献进行筛选整理，分别获得1 043篇和233篇有效文献样本。通过CiteSpace和VOSviewer软件对文献样本的发文年份、国家、作者和研究机构以及关键词等方面进行可视化分析，研究结果表明：中国在养殖废水处理技术领域的研究占据主导地位，热度远高于其他国家。国内外研究该领域的核心学科均为环境类，但农业、工程类及生物、化学等学科也对该领域的发展做出一定贡献，这种跨学科性质促进了处理技术的更新和创新，有助于处理复杂的污染物。但目前该领域尚未形成紧密的全球合作网络，未来跨机构合作潜力大。近10 a来，该领域研究已向高效、无二次污染的新型处理方向转变，有效处理的污染物种类不断增多，并对可持续性和资源、能源回收更加重视。
