【摘要】 采用初沉隔油、生物接触氧化、絮凝沉淀、消毒、过滤的工艺处理电厂总排废水。实际运行结果表明,该工艺处理效率高,运行稳定,出水浊度不大于5 NTU,CODMn含量不大于5 mg/L,NH3-N含量不大于1 mg/L,达到了电厂循环冷却水补充水水质要求,既节约了水资源,又降低了生产成本,具有良好的经济效益和环境效益。更多还原

【Abstract】 The total waste water of power station was treated by using the technology of the beginning sinks to separate the oil,bio-contact oxidation,flocculation-sedimentation,disinfection and filter.The practical operation results show that the process has high efficiency and stability.Using this process,effluent with turbidity≤5 NTU,COD Mn≤5 mg/L,NH 3-N≤1 mg/L has been obtained,this meets the make-up water standard of circulating systems,thus conservated the resources of water and lowered the production cost,achieved good environmental performance and economic performance.更多还原
