摘　　要：某工业园区进水为含氟废水与其他综合废水分开收集。针对低浓度含氟废水,采用络合—吸附—集聚—循环回流组合协同除氟方式及二级除氟过程,配合成品除氟剂,出水氟化物降至1.5 mg/L以下。除氟后的含氟废水再与其他综合废水均质混合后进入后续处理段。针对难降解污染物指标COD和TN,深度处理采用深床反硝化滤池和臭氧催化氧化工艺。通过小试和中试,验证了工艺的可行性,优化了主要设计参数的选取。The influent wastewater of a comprehensive industrial park was collected separately from the fluoride wastewater and other comprehensive wastewater.For low concentration fluoride wastewater,the combination of complexation-adsorption-agglomeration and cyclic reflux was used to defluorinate,the secondary defluorination process and the fluorine removal agent were used to reduce the effluent fluoride to less than 1.5 mg/L.After defluorination,the fluorine-containing wastewater was mixed with other comprehensive wastewater and then entered the subsequent treatment section.For difficult pollutants such as COD and TN,deep-bed denitrification and catalytic ozone oxidation processes were used for advanced treatment.Through laboratory tests and pilot tests,the feasibility of the process was verified,and the selection of main design parameters was optimized.
