Iron carbon reaction tower
The iron carbon reaction tower adopts steel liningPPMaterial and water treatment capacity:80 m3/dDesign dimensionsD 2.0 m×4.0 mEffective water depth3.5 mHydraulic retention time3 h. Internal loading6 m3A new type of iron carbon microelectrolysis filler, produced using high-temperature microporous activation technology, with an average particle size of12~14 mmBulk density1.0~1.2 g/cm3Specific surface area1.3 m2/gPorosity rate≥65%Due to the organic combination of micro electrolysis positive and negative electrode materials and catalytic elements, the discharge reaction is unobstructed, avoiding phenomena such as passivation and plate formation of the filler during operation.
