Activated carbon ( AC) is significant media in establishing a well performed bio -enhanced AC filter ( BEAC ) .It requires abundant mesoporous pores in terms of high absorp-tion capacity for macromolecular substances , suitable surface environment for multiplication and biodegradation of functional bacteria .Aiming at regulating pore structure and adsorption property to overcome shortages of the commercial microporous AC in water purification , opti-mizations of coal-blending and preparation procedure were conducted .An innovative high-efficient activated carbon was prepared by innovative procedures using optimal coal -blending as precursor .Surface chemical and physical properties and long -term performance of the new-type carbon in bio-enhanced activated carbon ( BEAC ) were investigated .Re-sults suggested that coal -blending of Datong Coal (10%) and Ningxia Coal (90%) was i-dentified as the optimal scheme .Combination of oxidation and depth -steam -activation were introduced in procedure GY -4.Carbon sample CGY -4 obtained from GY -4 a-chieved higher iodine number (1 185 mg/g), methylene blue (271.8 mg/g), BET surface area (1 316 m2/g), total pore volume (1.149 cm3/g) and mesoporous porosity (65.59%) .In comparison with commercial GAC ( ZJ15 ) , CGY -4 performed better in BEAC process ( BC-CGY-4) with higher removal efficiencies of COD Mn and higher levels of ATP biomass, increasing by 17.35 % and 27.97 %, respectively.Therefore, carbon CGY-4 was identified as an optimal biological carrier and adsorbent .
