摘要
为考察生物强化技术对污水系统污染物去除能力和稳定性的改善情况,验证生物强化技术在炼油废水处理中的应用效果,开展了生物强化技术处理炼油废水的中试研究。结果表明,经过生物强化培养后,COD去除率由原来的平均78.23%～78.75%提升至86.48%～89.09%,氨氮去除率由原来的平均58.40%～90.96%提升至95.51%～96.96%,污泥沉降性大幅改善,出水悬浮物明显减少。
A pilot plant process to treat refinery wastewater was operated to investigate the performance of biological augmentation technology of decontaminate and the improvement of stability. It showed that with the biological augmentation cultivation, averagely the removal rates of COD and ammonia nitrogen were improved from 78.23% -78. 75% to 86. 48% - 89. 09% and from 58.40% - 90. 96% to 95.51% - 96.96% respectively. The sludge sedimentation performance improved greatly and the suspended material of the effluent reduced significandy.
