摘　　要：现代煤化工企业废水处理面临水量大、污染物复杂等挑战。文章针对这一问题,设计了“预处理+混凝沉淀+厌氧+好氧MBR+NF软化+RO脱盐”工艺流程,通过实验验证其对COD、氨氮、酚类等污染物的去除效果。实验结果表明,该工艺可有效去除废水中的主要污染物,出水指标满足工业回用标准,且实现了高达90%以上的回用率,为煤化工废水的深度处理与资源化利用提供了参考。Modern coal chemical enterprises face challenges such as large volumes of wastewater and complex pollutants in wastewater treatment.This paper addresses this issue by designing a process flow of“pre-treatment+coagulation precipitation+anaerobic+aerobic MBR(membrane bioreactor)+NF(nanofiltration)softening+RO(reverse osmosis)desalination”.Through experiments,the removal efficiency of this process for pollutants such as COD(chemical oxygen demand),ammonia nitrogen,and phenols was verified.The experimental results show that this process can effectively remove the main pollutants in the wastewater,with effluent standards meeting industrial reuse criteria,and achieving a reuse rate of over 90%,providing a reference for advanced treatment and resource utilization of coal chemical wastewater.
