The results showed that the bacteria B7 came into the logarithmic growth phase for 5 h culture. Both the fermentation liquid and its filtration could inhibit C. colhounii effectively, and the fermentation of dilution l0 times also showed significant differences compared with the control. The inhibiting effect of its fermentation media filtration was even more significant in the optimizing test, with the maximal inhibition rate of 100%. The best fermentation condition was 0.5% glucose, 0.1% ammonium muriate, without extra mineral, pH 5.4, temperature 28℃. Based on the morphological properties and 16S rRNA sequence, the bacterium B7 was identified as the Bacillus subtilis.

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.

采用浸没式膜生物反应器处理焦化废水的试验结果表明：膜的截留作用可使硝化菌在反应器内富集而有利于提高系统的硝化能力，其去除氨氮的最高负荷为0.19kg/(m3·d)，出水氨氮＜1mg/L(去除率为99%)；泥龄长可能使微生物的代谢产物或其他大分子物质积累，从而抑制硝酸盐细菌的活性，导致NO2-积累而有利于短程脱氮的进行，但泥龄过长也会影响亚硝酸盐细菌的活性，从而影响对氨氮的处理效果。
