摘　　要：随着进水变化以及现有设备损耗,污水处理厂的达标排放压力越来越大。绍兴柯桥江滨水处理有限公司需新建深度处理工程,采用炭加载磁混凝高效沉淀工艺。详细介绍了该工程的设计、运行效果及经济性能等情况,总结了运行管理经验。该工程自2019年4月投运以来,运行稳定,运行成本约0.84元/m^(3),出水COD、TN、TP等14项指标均满足《纺织染整工业水污染物排放标准》(GB 4287—2012)中新建污水处理厂直接排放标准。该工程实践证明,炭加载磁混凝高效沉淀工艺是综合印染废水深度处理的较好工艺选择之一。It is more difficult to meet wastewater discharge standards with influent quality change and treatment equipment damage.Hence,Keqiao Jiangbin wastewater treatment plant(WWTP)in Shaoxing needs to build a new advanced treatment project,which adopts carbon-loaded magnetic coagulation and high efficiency sedimentation process.The design,operation effect,economic performance of the project are elaborated,and then operation management experience is summarized.Since April 2019,it had been running steadily,with the operating cost of about 0.84 yuan/m^(3),and 14indicators such as effluent COD,TN,TP could satisfy the direct discharge standard for new WWTP in Discharge Standards of Water Pollutants for Dyeing and Finishing of Textile Industry(GB 4287-2012).The project practice has proved that carbon-loaded magnetic coagulation and high efficiency sedimentation is a good choice for advanced treatment of comprehensive printing and dyeing wastewater.
