EXPERIMENTAL STUDY OF FILLER COMPACTION FORMING PROCESS IN FERRIC-CARBON MICRO-ELECTROLYSIS

Micro-electrolysis has been successfully applied in the treatment of high-concentration organic wastewater because this method can provide certain advantages, such as wide application range, good treatment effect, easy operation, and effective waste control. However, compacted iron and carbon filler in wastewater treatment can affect the ability of micro-electrolysis to remove water pollutants. This study applied scanning electron microscopy and energy-dispersive spectroscopy to analyse the surface of iron carbon filler after micro-electrolysis. The analyses were performed based on micro-electrolysis treatment of asphalt wastewater. Results showed a layer of iron oxide passivation film on the surface of the iron carbon filler. This layer can be removed by backwash, thereby improving the treatment effect.
