Comparison of ozone-based AOPs on the removal of organic matter from the secondary biochemical effluent of coking wastewater.

Advanced oxidation processes (AOPs) based on ozone are gaining continuously growing popularity in wastewater treatment. This study explored the treatment of coking wastewater using a combination of ozonation (O), ultraviolet (UV), and hydrogen peroxide (HO) process expressed by % chemical oxygen demand (COD) removal, % total organic carbon (TOC), % UV, % fluorescence intensity removal and its electrical energy consumption. The obtained results demonstrated that, the combination of O, UV, and HO which is denoted by O/UV/HO in this study achieved great success in COD removal (92.

Preparation of Tin-Antimony anode modified with carbon nanotubes for electrochemical treatment of coking wastewater.

To improve the electrocatalytic activity, carbon nanotubes (CNTs) were used to modify a titanium-supported tin-antimony anode (Ti/SnO-Sb). Compared to a Ti/SnO-Sb anode, the Ti/SnO-Sb-CNTs anode exhibited a higher oxygen evolution potential (1.62 V), smaller crystalline volume (71.
