Coking wastewater contains a variety of organic substances which are difficult to decompose, including phenols, polyeyclic aromatic hydrocarbons (PAHs), and nitrogen-containing heteroeyclic compounds (NHCs). These substances are potentially harmful to the ecological environment. Traditional wastewater treatment technologies are often difficult to effectively remove these toxic and harmful pollutants. The research and development of efficient treatment methods for coking wastewater has attracted great attention and widespread concem in the industry in recent years. This paper reviewed the research progress of the coking wastewater treatment technology, focusing on the sources, characteristics, pretreatment technology, biochemical treatment and advanced treatment technology of wastewater. In addition, this paper discussed the zero-discharge strategy of coking wastewater as well as the demand for coking wastewater treatment technology to reduce energy consumption and increase efficiency. The zero-discharge strategy realizes resourceful use of wastewater and minimizes the environmental impacts through the integration of processes. Future research will focus on reducing energy consumption , resource recovery and reuse, and process optimization to achieve green and low-carbon development of coking wastewater treatment technology.
