| 摘 要： | 西北干旱地区某校园污水先采用水解酸化阶段-产甲烷阶段分离的厌氧生物处理及两级生物接触氧化处理,出水再进行滤布滤池深度处理。结果表明,该工艺能有效地将高有机物浓度、高氨氮的校园生活污水处理后达到城市污水再生利用杂用水的水质标准。该工程利用厌氧污泥回流到产甲烷阶段前,腐殖污泥回流到水解酸化池并加大污泥回流率的方法,基本无剩余污泥排放。

| Abstract: | The combined process of hydrolytic acidification,methane production phase separation,two-stage biological contact oxidation and filter cloth filtration was used to treat campus sewage in the northwest arid region.The results showed that the process could efficiently treat the campus sewage with high concentration of organic matter and ammonia nitrogen to meet The Reuse of Urban Recycling Water—Water Quality Standard for Urban Miscellaneous Water Consumption(GB/T 18920-2002).In this project,anaerobic sludge was refluxed to methane production stage,humus sludge was refluxed to hydrolytic acidification tank,and the sludge reflux rate was increased,so that almost no residual activated sludge was discharged. |
