【Abstract】 A biofilm - activated sludge protiess is used to treat coke plant wastewater. Results of a smail - scale test and a full - scale tes t show that COD and ammonia nitrogen can be removed efficiently in the process. The removal efficiency of COD and ammonia nitrogen is 80%～ 95% and 94%～ 99.9% respectively. Other pollutants concentrations are als o lower than those in the wastewater discharge standards of China.更多还原
