| Abstract: | Microorganism-immobilized biological aerated filter was used to treat coke-plant wastewater,and make a research on treatment of coke-plant wastewater,the experiment to determine the best conditions for operation of the technology.Experimental operating conditions： the design capacity is 4～6m^3 /h,biochemical hydraulic retention time was 25～50h,anaerobic is 13～22h,aerobic is 20～28h、aeration is 40∶1.The average removal rates of CODcr,NH3-N,CN are 95.4%,96.1% and 99.1% respectively.The results show that after the treatment,the effluent quality of coke-plant wastewater can achieve the second requirement of GB8978—1996. |
