静电除菌技术在污水再生处理中的应用

Application of Electrostatic Bacteria Removal Technology to Wastewater Reclamation and Reuse

在某再生水回用工程中,以污水厂二沉池出水为进水,采用了混凝沉淀—静电除菌处理技术,出水细菌总数<100个/mL、大肠菌群<3个/L、SS<0.5 mg/L、浊度<1 NTU、SD I<3,稳定达到《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)。出水回用作冲厕、绿化、景观及车辆冲洗用水。

The effluent from secondary sedimentation tank of sewage treatment plant was used as the influent, and the coagulation sedimentation and electrostatic bacteria removal technology were adopted in a wastewater reclamation and reuse project. After treatment, the total bacteria count, total coliform count, SS, turbidity and SDI are less than 100 CFU/mL, 3 CFU/L, 0.5 mg/L. 1 NTU and 3 respectively. The treated effluent stably achieves the Reuse of Urban Recycling Water--Water Quality Standard for Urban Miscellaneous Water Consumption （ GB/T 18920 - 2002 ） . and can be reused for toilet flushing. greening, landscape and car washing.
