Advanced treatment of biologically pretreated coal gasification wastewater by a novel integration of heterogeneous catalytic ozonation and biological process.

abstract：:Terracotta pots were converted into simple, single chamber, air-cathode bio-batteries. This bio-battery design used a graphite-felt anode and a conductive graphite coating without added catalyst on the exterior as a cathode. Bacteria enriched from river sediment served as the anode catalyst. These batteries gave an av...
