摘要
考察了不同阶段运行时间的设置、水力停留时间、溶解氧浓度和污泥龄条件下,一体化活性污泥法除磷脱氮的规律。结果表明,将系统控制在适宜的条件下,出水NH3-N可达到污水综合排放一级标准。提出了后续研究中改善除磷效果的措施。
Under the conditions of the set of opreating time, hydraulic residence time, dissolved oxigen concentration and sludge age at different stages, the law of removing phosphorus and nitrogen by integrated active sludge method was investigated. The results showed that when the system was controlled under proper conditions, NH3--N in effluent could reach the standard of one-class discharge of sewage. In addition, the measures to improve the effect of phosphorus removal were put forward in subsequent research-
