苏中某工业园区废水深度处理案例分析

苏中某工业园区污水处理厂设计规模30 000 m/d,接纳电子,光伏等难处理废水,因水质成分复杂,出水标准严苛,拟构建"改良AAO+MBR+深度处理"工艺以实现对该工业区废水深度处理.改良AAO通过厌氧—缺氧—好氧—后缺氧四段式生化反应提升脱氮效能,深度处理采用"臭氧催化氧化—高效沉淀—反硝化滤池"组合工艺.根据2024年实际运行结果显示,CODCr,NH3-H,TP,氟化物均值分别达到11,0.23,0.02,2.83 mg/L,均显著优于地表"GB 3838-2002"Ⅳ类水标准;出水TN浓度为2.9 mg/L,满足"GB 18918-2002"一级A标准.部分出水回用于道路浇洒和厂区绿化等,剩余出水经生态安全缓冲区进一步净化处理.项目为同类工业废水处理提供了"生物强化+深度处理"的示范方案.

某工业园区污水处理厂及生态安全缓冲区工程设计

The wastewater treatment plant from an industrial park was designed with a capacity of 60 000 m/d (divided into two phases), with phase Ⅰ handling 30 000 m/d, primarily for treating photovoltaic industry wastewater. Based on water quality of influent and discharge standards, the design employed a combined process of high-density sedimentation hydrolytic acidification AAO high-density sedimentation ozonation biological filtration, supplemented by an ecological safety buffer zone. The ecological safety buffer zone adopted a surface flow constructed wetland, designed for the total discharge capacity of both phases (42 000 m/d). The two-stage high-density sedimentation process ensured fluoride compliance (≤1.5 mg/L), ozonation coupled with biological filtration degraded recalcitrant COD, and the ecological buffer zone further purified the effluent. Over nearly one year of operation, the average effluent COD was 18 mg/L and fluoride was 1.1 mg/L, meeting all Class A standards specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (DB 32/4440—2022) in Jiangsu Province. The system was operated stably, which demonstrated strong resistance to shock loads, and consistently achieved compliant effluent quality. With treatment cost of 4.2 yuan/t, the project demonstrated environmental, social, and economic benefits, serving as a model for high-standard treatment and ecological transformation of industrial fluoride-containing wastewater.
