- 摘要:
- 贵阳金百再生水厂设计规模为3.0×104 m3/d，出水水质执行《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准，就近作为麦架河河道生态补水。生化处理采用节地型生物膜技术，通过悬浮填料和高填充率的固定床结构，实现生物膜处理和生物过滤的双重作用，高效去除污染物，省去二沉池，节省占地面积。介绍了该厂的工艺流程、构筑物设计及设备配置情况，并对运行效果进行总结。自运行以来,出水水质稳定达标，COD、SS、氨氮、总氮、总磷去除率分别为89.4%、92.8%、96.3%、48.4%、90.9%;节地效果明显，吨水占地仅为0.36 m2/(m3·d-1);运行成本为0.56元/m3，与同等规模的传统活性污泥法污水厂的运行成本相近。
- Abstract:
- The effluent quality of Jinbai reclaimed water plant in Guiyang City, with designed treatment capacity of 30 000 m3/d, meets level Ⅰ- A of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) and recharged into Maijia River as replenishment. A hybrid biofilm reactor (HBR) was applied in bio-treatment process, which utilized high volumetric filling ratio of suspended carriers to achieve biofilm treatment and filtration simultaneously. This biofilm technology removed pollutants efficiently and saved plant footprint obviously by omission of secondary settling tank. This paper described the treatment process, structure design and equipment configuration of the plant, and also summarized the operation effect. The effluent pollutants meet the discharge standard since operation. The removal efficiencies of COD, SS, ammonia nitrogen, TN, TP are 89.4%, 92.8%, 96.3%, 48.4%, 90.9%, respectively. The footprint for unit treated wastewater is 0.36 m2/(m3·d-1). The operation cost is 0.56 yuan/m3, which is close to that of conventional activated sludge process with similar capability.
