基于文献计量学的畜禽养殖废水处理研究现状及发展趋势

Research status and development trend of livestock and poultry wastewater treatment based on bibliometrics

为全面了解畜禽养殖废水领域的研究进展,利用VOSviewer对Web of Science(WoS)核心合集数据库中2003—2023年畜禽养殖废水相关文献进行统计及可视化分析,通过关键词聚类分析,了解该领域的研究主线及多年变化。结果显示:畜禽养殖废水研究领域近3年发文量增长迅猛,截至2023年发文量已达4117篇,中国、美国学者对该领域研究的贡献度较高且合作密切;有机物、营养物质、致病菌、重金属和抗生素为畜禽养殖废水处理的主要污染物,其中,重金属和抗生素近年来引起了较多的关注,加强畜禽养殖废水中抗生素的监管与处理具有紧迫性;在时间尺度上的映射发现,畜禽养殖废水主要以生物处理技术为主,关键词microalgae-based wastewater treatment(微藻驱动废水处理)的平均出现年份为2022年,表明其为当前畜禽养殖废水处理的新兴技术。此外,还从污染物种类、处理技术方面探讨了畜禽养殖废水处理研究的不足及未来发展趋势,提出基于可持续发展观的低能耗、抗冲击、高附加值的处理技术可能是未来的研究重点,应在此基础上开发新的水处理技术及应用研究。

To comprehensively understand the progress of academic research in the field of livestock and poultry wastewater,VOSviewer was used to statistically and visually analyze the literature related to livestock and poultry wastewater in the Web of Science(WoS)Core Collection database from 2003 to 2023 and,through keyword clustering analysis,to understand the main lines of research in this field and the changes over the years.The results showed that the number of publications in the field of livestock and poultry wastewater research had grown rapidly in the past three years,the number of publications had reached 4117 by 2023,and Chinese and American scholars had contributed more to the research in this field and cooperated closely.Organic matter,nutrients,pathogenic bacteria,heavy metals and antibiotics were the main pollutants in livestock and poultry wastewater treatment,of which heavy metals and antibiotics had attracted more attention in recent years.It was urgent to strengthen the supervision and treatment of antibiotics in livestock and poultry wastewater.The mapping on the time scale revealed that livestock and poultry wastewater was mainly treated with biological treatment technology,and the average occurrence year of the keyword microalgae-based wastewater treatment was 2022,indicating that it was a new technology for the treatment of livestock and poultry wastewater.Besides,the research deficiencies and future development trends of livestock and poultry wastewater treatment were discussed in terms of pollutant types and treatment technologies,and it was proposed that low-energy consumption,shock-resistant,and high-value-added treatment technologies based on the concept of sustainable development may be the focus of future research,and that new water treatment technologies and applied research should be developed on this basis.
