Abstract

The coking industry produces a large amount of coking wastewater (CWW) per year. The complex composition and high salinity characteristics of CWW result in its toxicity and obstinacy. At present, the treatment requirements of CWW face the change from standard discharge to resource recovery. The deep mineralization of refractory organic matters in CWW is a key premise to realize its reuse. Advanced oxidation process (AOPs) is a prospective countermeasure because of its high oxidation capacity. There are many types of AOPs and the advantages and disadvantages of each AOP type for CWW treatment lack systematic analysis. Herein, from the perspective of the full life cycle, the composition characteristics of CWW and its complex causes are revealed. Then, the main limitations and possible optimization approaches of CWW processing in different AOPs are deeply analyzed. This review is expected to contribute to the sustainable development of the CWW industry.

高级氧化工艺在高含盐量焦化废水处理中的应用前景：支持可持续管理的战略

焦化行业每年产生大量焦化废水（CWW）。焦化废水成分复杂，含盐量高，具有毒性和顽固性。目前，焦化废水的处理要求面临着从达标排放到资源回收的转变。实现中水回用的关键前提是中水难溶有机物的深度矿化。高级氧化工艺（AOPs）因其高氧化能力而成为一种有前景的对策。高级氧化工艺的种类繁多，各种类型的高级氧化工艺在处理化武过程中的优缺点缺乏系统分析。本文从整个生命周期的角度，揭示了化武的成分特点及其复杂成因。然后，深入分析了不同 AOP 处理 CWW 的主要局限性和可能的优化方法。本综述有望为化武行业的可持续发展做出贡献。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
