摘要
西安市某医院新建污水处理站采用生化法-流化床工艺,重点强化了对污水、污泥、废气、噪声的处理,平均进水ρ(CODcr)=400 mg/L,平均出水ρ(CODcr)=50 mg/L,CODcr平均去除率为87.5%。实践结果表明,该工艺运行费用低,操作简便,易于维护,处理效果稳定,其出水各项指标均优于《黄河流域(陕西段)污水综合排放标准》(DB 61/224-2011)二级标准。其出水各项指标均优于《医疗机构水污染物排放标准》(GB 18466-2005)一级标准。
A hospital wastewater treatment project in the Xi＇an City adopted the process of biochemical-fluidized bed which focus on strengthening the wastewater,sludge,exhaust gas and noise treatment. With influent CODcrof 400 mg / L,effluent CODcr of 50 mg / L,the average of CODcrremoval was 87. 5%. The operation results showed that the treatment cost was low and the treatment effect was stable,convenient for management and operation. The effluent qualities could meet the water quality of the effluent water Discharge standard of water pollutants for medical organization（ DB61 /224-2011）.
