摘要
为确保鄱阳湖生态经济区水资源安全,提高江西某化工园区污水处理厂的主要出水指标,采用"上流式厌氧污泥床(UASB)+A/O+臭氧氧化+缺氧+生物接触氧化+曝气生物滤池(BAF)"工艺进行提标改造。实际运行结果表明,COD、NH_(3)^(-)N去除率能分别达到80.2%、78.6%,出水TN、TP的质量浓度分别小于20、1 mg/L,各水质指标能够到达DB 36/852-2015中的"高效集约发展区"标准,废水的处理成本为4.43元/m^(3)。
In order to ensure the safety of water resources in the Poyang Lake Ecological Economic Zone and improve the discharge standard of a wastewater treatment plant in a chemical park in Jiangxi,the combined process of"UASB+A/O+Ozone Oxidation+Anoxic+Biological Contact Oxidation+BAF"was used for upgrading and reconstruction.The actual operation results showed that,the removal rates of COD and NH3-N reached 80.2%and 78.6%,respectively,and the mass concentrations of TN and TP in effluent were less than 20 m/L and 1 mg/L,respectively.The effluent quality met wastewater discharge standards of’the high efficient and intensive development zone’of DB 36/852-2015,while the treatment cost of wastewater was 4.43 yuan/m^(3).
