Produced water (PW) is the largest waste stream generated in oil and gas industries. The drilling and extraction operations that are aimed to maximize the production of oil may be counterbalanced by the huge production of contaminated water (called PW) with pollutants, such as heavy metals, dissolved/suspended solids, and organic compounds. PW is conventionally treated through different physical, chemical, and biological methods. In offshore platforms, because of space constraints, compact physical and chemical systems are used. However, major research efforts are being developed with innovative technologies for treating PW in order to comply with reuse and discharge limits. Among them, electrochemical technologies have been proposed as a promising alternative for the treatment of this kind of wastewaters. Then, this paper presents a minireview of efficient electrochemical technologies used until now for treating PW generated by petrochemical industry.
产出水（PW）是石油和天然气工业中产生的最大废水。为了最大限度地提高石油产量而进行的钻井和开采作业，可能会因污染物（如重金属、溶解/悬浮固体和有机化合物）而产生大量受污染的水（称为 PW）。PW 通常通过不同的物理、化学和生物方法进行处理。在海上平台上，由于空间限制，使用紧凑的物理和化学系统。然而，正在开发具有创新性技术的主要研究工作，以处理 PW，以符合再利用和排放限制。其中，电化学技术已被提议作为处理这种废水的一种很有前途的替代方法。本文对迄今为止用于处理石化行业产生的 PW 的高效电化学技术进行了综述。
