摘要

The expansion of unconventional oil and gas extraction has significantly increased the generation of high-NaHCO3 produced water, characterized by high salinity (total dissolved solids > 30,000 mg/L), high alkalinity (NaHCO3 > 5,000 mg/L), and severe scaling potential. These complex characteristics render conventional treatment methods ineffective, as they are often plagued by low efficiency, high operational costs, and membrane fouling. This review aims to systematically assess treatment technologies applicable to high-NaHCO3 produced water and to identify sustainable treatment strategies. A systematic literature search was conducted in the Web of Science Core Collection covering publications from January 2007 to October 2025. Bibliometric analysis using CiteSpace software was employed to map research trends, key topics, and influential studies in the broader field of produced water treatment. The review critically evaluates ion exchange, chemical precipitation, membrane processes (nanofiltration, reverse osmosis, membrane electrolysis, bipolar membrane electrodialysis), thermal methods (multi-effect distillation, membrane distillation), and microalgae-based bioremediation. Key findings indicate that integrated membrane systems offer synergistic benefits in desalination and scaling control, while electro-membrane technologies enable simultaneous salt removal and resource recovery of acids and bases. Microalgae cultivation presents a promising pathway for carbon fixation and biomass valorization. No single technology is universally optimal; multi-technology integration based on site-specific conditions is essential to balance treatment efficiency, energy consumption, and resource recovery. This review provides a technical reference for researchers and engineers addressing high-alkalinity produced water, supporting the sustainable development of the oil and gas industry.
