微电解-芬顿-UASB-A/O-生物接触氧化法处理制药废水
|
摘要
针对化学合成类制药废水具有成分复杂难降解、COD高、出水不稳定等特点,采用微电解-芬顿-上流式厌氧污泥床(UASB)-A/O-生物接触氧化法对其进行深度处理。介绍了工艺选择的依据、工艺流程、工艺参数及运行效果。实际运行结果表明,该工艺处理效率高、运行稳定。最终出水COD、BOD5和SS、NH3-N的质量浓度分别为74mg/L、19.4 mg/L和16、9.1 mg/L,去除率分别为98.9%、99.2%和97.7%、92.1%,出水水质满足GB 21904-2008排放要求。
Based on the characteristics of complexity, anti-biodegradably, high COD and effluent instability of pharmaceutical wastewater, using the process of microelectrolysis-Fenton-UASB-A/O-BCO to treat it. The process selection base, process flow, technological parameters, and running efficacy were introduced. The running results showed that the process had high treatment efficiency and stability. The effluent COD, BOD5 and mass concentration of SS, NH3-N reached 74 mg/L, 19.4 mg/L, and 16 mg/L and 9.1 mg/L respectively, the removal rate reached 98.9%, 99.2%, 97.7% and 92.1% respectively.The water quality of effluent met the discharge standard of GB 21904-2008.
