摘要

Oilfield produced water (PW) is the largest wastewater stream generated during petroleum extraction and remains difficult to treat because of its high salinity, complex composition, and highly variable pollutant loads. We performed a hot-spot analysis of electrochemical PW treatment by integrating CiteSpace-based bibliometrics with an engineering-oriented performance normalization. A total of 216 Web of Science Core Collection articles (2004–2024) were analyzed to map publication dynamics, collaboration patterns, and thematic evolution. Keyword co-occurrence and burst analyses identify anode material development, current–density regulation, and hybrid electrochemical systems as dominant research hot spots. To strengthen engineering relevance beyond descriptive mapping, we developed a normalized electrochemical performance index (Φ) that integrates pollutant removal efficiency, specific energy consumption, and operational stability. Linking bibliometric clusters to Φ shows that studies emphasizing advanced anodes and process integration achieve higher composite scores (Φ = 0.72–0.83), whereas conventional electrocoagulation without energy or durability optimization remains below 0.60. Reported data synthesis further indicates that electrochemical oxidation and electro-Fenton are adaptable to high-salinity PW, delivering average COD removal above 85.6% under optimized conditions. Overall, this “bibliometrics + performance” framework helps prioritize scalable, energy-efficient, and sustainable electrochemical treatment directions for produced water management.
