UASB-氨吹脱-氧化沟-反渗透处理垃圾渗滤液
|
摘要
针对垃圾渗滤液具有成分复杂、氨氮含量高、水质水量变化大等特点,采用上流式厌氧污泥床(UASB)-氨吹脱-循环折流式(Carrousel)氧化沟-反渗透(RO)工艺对其进行深度处理。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,该工艺运行稳定,处理效率高。最终出水COD、BOD_5和SS、NH_3~-N的质量浓度分别为74 mg/L、12 mg/L和7.6、9.1 mg/L,大肠杆菌数800个/L,去除率分别高达99.0%、99.7%、99.6%、99.4%、99.9%,出水水质满足GB 16889-2008表2的要求。
Aimed at the characteristics of complexity, high-content ammonium and great variation of leachate, the process of UASB-ammonia strippingcarrousel oxidation ditch-RO was used for it advanced treatment. Its 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 COD, BOD_5, mass concentration of SS and NH_3~-N, Escherichia coli in effluent was 74 mg/L, 12 mg/L, 7.6 mg/L, 9.1 mg/L and 800/L respectively, the removal rate reached 99.0%, 99.7%, 99.6%,99.4% and 99.9% respectively. The effluent quality met the Table. 2 requirement of GB 16889-2008.
