A submerged membrane sequencing batch bioreactor was used to treat coke wastewater.Long running performance showed that due to the membrane interception,the nitrobacter is enriched in reactor in the interest of improving the nitrification rate;the maximum ammonia nitrogen loading can be 0.19 kg/(m3·d) with effluent ammonia nitrogen＜1 mg/L (removal rate 99%).Long sludge retention time may result in the accumulation of metabolic products and high molecular materials,and thus inhibiting activity of nitrate bacteria and causing a ccumulation of NO2-,which is beneficial to the running of short-cut denitrif ication.However,too long retention time will affect the activity of nitrite bacteria,detrimental to the treatment effect of ammonia nitrogen.
