摘要
造纸废水在受到氨氮冲击硝化系统受损效率降低情况下,通过外源添加倍活降氨氮菌后,硝化系统第2d开始逐渐恢复,氨氮去除率由8%增长到35%,第三天氨氮去除率由35%增长到87%。与此同时外源菌种添加并未造成系统出现其他问题,系统CODcr去除率在90.5%-91.7%之间,非常稳定。
Papermaking wastewater under the condition of reducing the damage efficiency of the system under the impact of ammonia nitrogen, Add by exogenous MicroPlex -N, Nitrification system second days began to gradually recover, The removal rate of ammonia nitrogen increased from 8% to 35% ,Ammonia nitrogen removal rate increased from 35% to third in 87% days. At the same time, the addition of exogenous bacteria did not cause other problems in the system,The removal rate of CODcr was between 90.5 % - 91.7 %, Very stable.
