摘要：
A hopper bottom electro chemical reactor with rotating 3D anode is attempted to avoid commonly encountered problems in electrochemical reactor like short circuiting, development of dead zones, formation of oxide layer on anode surface etc. The RTD experiments and CFD simulations established that the present configuration is free from these operational difficulties. The simulated synthetic textile wastewater is treated in the proposed configuration. A higher COD removal efficiency (96.40%), color removal efficiency (99.88%) and low specific energy consumption (0.028 J/mg) are observed vis-a-vis stationary 3D anode reactor.
