Abstract:

The characteristics of the coke wastewater such as great volume, complexity on contaminations' composition and high concentration of contaminations are introduced, so do the traditional treatments of the coke wastewater and their shortcomings. Then, a new technology, the catalytic wet oxidation process (CWO), is put forward. The treatment of coke wastewater for the CWO is analyzed by the study of economic and technological practicability, which suggests this process is feasible technologically and has good cost effect. Furthermore, some problems about industrialization of CWO are brought forward.

Key words: coke wastewater, catalytic wet oxidation process (CWO), activated sludge
