Dual treatment of raw hospital wastewater (RHWW) is investigated by coupling electrochemical coagulation (ECC) with the activated sludge process (ASP) to achieve the goal of partial mineralization and reclaim quality water. The quality parameters of focus were chemical oxygen demand (COD), color, mixed liquor suspended solids (MLSS), total dissolved solids (TDS), chloride, total alkalinity, and fecal coliform. The initial ECC process with short hydraulic retention time (HRT) could remove 75–82% of the insoluble constituents in <60 min, while the HRT for ASP was >7–8 h. The combined ECC + ASP hybrid treatment process showed effective removal of COD, color, TDS, and fecal coliform by 98.5, 99.6, 83.1, and 97.9%, respectively, from its initial values of 4,000, 2,200, 77, and 2,400 MPN/100 mL, respectively. By coupling ECC and ASP, both the insoluble and soluble pollutants/contaminants in the RHWW were removed effectively. The ECC–ASP dual treatment offers a small energy and spatial footprint for mineralizing RHWW.

研究通过电化学混凝（ECC）与活性污泥法（ASP）耦合对医院原废水（RHWW）进行双重处理，以达到部分矿化和回用优质水的目的。重点质量参数为化学需氧量（COD）、色度、混合液悬浮物（MLSS）、总溶解性固体（TDS）、氯化物、总碱度、粪大肠菌群。具有短水力停留时间（HRT）的初始ECC工艺可以在<60分钟内去除75-82%的不溶性成分，而ASP的HRT>7-8小时。ECC + ASP 组合混合处理工艺显示，其 COD、颜色、TDS 和粪大肠菌的有效去除率分别比初始值 4,000、2,200、77 和 2,400 MPN/100 分别提高了 98.5%、99.6%、83.1% 和 97.9%分别为毫升。通过耦合ECC和ASP，RHWW 中的不溶性和可溶性污染物均得到有效去除。ECC-ASP 双重处理为 RHWW 矿化提供了较小的能源和空间足迹。
