Petroleum industry is one of the fastest growing industries, and it significantly contributes to economic growth in developing countries like India. The wastewater from a petroleum industry consist a wide variety of pollutants like petroleum hydrocarbons, mercaptans, oil and grease, phenol, ammonia, sulfide, and other organic compounds. All these compounds are present as very complex form in discharged water of petroleum industry, which are harmful for environment directly or indirectly. Some of the techniques used to treat oily waste/wastewater are membrane technology, photocatalytic degradation, advanced oxidation process, electrochemical catalysis, etc. In this review paper, we aim to discuss past and present scenario of using various treatment technologies for treatment of petroleum industry waste/wastewater. The treatment of petroleum industry wastewater involves physical, chemical, and biological processes. This review also provides scientific literature on knowledge gaps and future research directions to evaluate the effect(s) of various treatment technologies available.
石油工业是发展最快的行业之一，它为印度等发展中国家的经济增长做出了重大贡献。石油工业的废水含有多种污染物，如石油碳氢化合物、硫醇、油和油脂、苯酚、氨、硫化物和其他有机化合物。所有这些化合物在石油工业排放的废水中都以非常复杂的形式存在，它们直接或间接地对环境有害。一些用于处理含油废物/废水的技术有膜技术、光催化降解、高级氧化工艺、电化学催化等。在这篇综述论文中，我们旨在讨论过去和现在使用各种处理技术处理石油工业废物/废水的情况。石油工业废水的处理涉及物理、化学和生物过程。本文还提供了关于知识空白和未来研究方向的科学文献，以评估各种现有处理技术的效果。
