Coke making process is strictly connected with formation of coke oven wastewater, highly loaded and contaminated stream, proper treatment and utilization of which requires sophisticated methods and technologies. This wastewater is defined as a mixture of technological streams, which are formed during coke oven gas cleaning and coal-derivatives production, and sanitary wastewater formed at coke oven plant. Due to the composition and specificity of contaminants present in coke oven wastewater, its proper treatment requires the involvement of physical, chemical and biological methods, which are often proceeded with additional polishing. In dependence on its further use (deposition to environment or wet quenching of coke) different types of contaminants are found to be priority substances, removal of which during the stream treatment is especially important. In the article, a literature review on coke production, coke oven wastewater formation, its parameters, applied technologies of treatment and utilization methods is presented. The special attention was given to the applied treatment techniques, which were found to be the key factor in further stream utilization. Additionally, issues related with nowadays used systems were pointed out.
