Research Frontiers and Hotspots for the Sludge Pretreatment from 2010 to 2020 — Based on the Bibliometrics Analysis of WoS Database
Abstract
Sludge pretreatment is important to the reduction,harmlessness and recycling of sludge.In order to clarify the frontiers and hotspots of international research in the field of sludge pretreatment in the past 10 years,taking the core data collected by Web of Science from 2010 to 2020 as the research object,this paper adopts bibliometrics methods and CiteSpace visualization tools to analyze the number of papers published,country,institution,journal,author and keywords.The results show that:In recent ten years,sludge pretreatment technology has been widely concerned,and China has an absolutely leading position in this area.The number of publications presents a trend of exponential increase,and they are mainly published on top journals such as Bioresource Technology,Water Research,with great academic influence.Researches mainly focus on the impact of pretreatment technology to sludge digestibility,changing mechanism and practical engineering,etc.In addition,the optimization and technological conditions of pretreatment methods will become main research hotspots in the future.This paper clearly summarizes the research status,development course and hotspot change of sludge pretreatment,providing reference and strategic thinking for future study.
