【摘要】 在造纸废水处理生化好氧段加入生物活性氮磷合剂替代普通固体复合肥,提高系统COD去除率约6%,增加活性污泥浓度,使MLSS稳定在4300 mg·L-1,出口氨氮值小于0.8 mg·L-1,最后结合生物相观测得出,活性氮磷合剂可加快微生物的生长繁殖,提高系统的处理效率及稳定性。更多还原

【Abstract】 Adding biological active nitrogen and phosphorus mixture instead of ordinary solid compound fertilizer during the biochemical aerobic section of the papermaking wastewater treatment can increase COD removal efficiency of the system about 6%, and increase the active sludge concentration maintaining MLSS at a stable 4300 mg·L-1. At the same time, the value of export ammonia can be reduced less than 0.8 mg·L-1. Finally, combining with biological observations, it can be found that biological active nitrogen and phosphorus mixture can accelerate the growth of microbial breeding and improve the processing efficiency and stability of the wastewater treatment system.更多还原
