接触氧化-地下渗滤工艺在校园污水处理中的应用

Combined Process of Biological Contact Oxidation and Subsurface Wastewater Infiltration System for Campus Sewage Treatment

结合沈阳大学新校区生活污水处理厂建设实例,介绍了生物接触氧化-地下渗滤联合工艺深度处理校园生活污水的工艺原理、工艺流程及处理效果,并对地下渗滤系统的运行方式和基质组配方法等方面进行了探讨.实践证明,该联合工艺处理校园生活污水,具有运行稳定,管理操作简便,运行费用低等优点,出水各项水质指标均优于《城市污水再生利用—景观环境用水水质》标准(GB/T 18921-2002).

Combining with the new campus wastewater treatment project in Shenyang University, the combined process of biological contact oxidation technology and subsurface wastewater infiltration system was introduced, especially the treatment principles, procedures and pollutants removal effects. The operation mode and substrate composition method of SWIS were discussed. The results showed that the combined process could treat the campus sewage consistently with high pollutants removal rates, and low management and operating cost. The effluent quality can meet the requirements of Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use （GB/T 18921-2002）
