摘　　要：针对某循环经济示范园光伏企业排放的含氟污水成分复杂、 NH3-N和F-浓度高、可生化性低的特点,设计采用以芬顿氧化-水解酸化-AO生化-臭氧氧化-曝气生物滤池为主的组合工艺。该工程运行结果表明,在进水COD、 NH3-N、 TN、 TP、 F-的质量浓度分别为280、 35、 50、 4、 8 mg/L的条件下,出水水质可稳定达到DB34/2710—2016《巢湖流域城镇污水处理厂和工业行业主要水污染物排放限值》表2中的城镇污水处理厂I标准,且出水ρ(F-)≤1 mg/L。该工艺处理效果稳定,具有较强的抗冲击负荷能力,运行成本及动力消耗低。In view of the characteristics of fluorine-containing sewage discharged from enterprises in a circular economy demonstration park such as:complex components,high NH3-N and F-concentrations,low biodegradability and so on,a combined process of Fenton oxidation-hydrolytic acidification-AO biochemical-ozone oxidation-biological aerated filter was adopted in the design.The project operation results showed that,when the mass concentrations of COD,NH3-N,TN,TP and F-in the inffluent water were 280,35,50,4,8 mg/L respectively,the effluent water quality could stably meet the requirement of urban sewage treatment plantⅠstandard in table 2 of DB34/2710—2016 Chaohu lake basin urban sewage treatment plant and iIndustrial discharge limits of major water pollutants,the mass concentration of F-in the effluent water was not above 1 mg/L.The said process has stable treatment effect,strong impact load resistance,low operating cost and power consumption.
