摘要
对UNITANK法的传统运行模式做了改进。在此基础上,考察了水力停留时间、溶解氧浓度和泥龄等重要因素对处理效果的影响。结果表明,将系统控制在适宜的条件下,出水COD和NH3-N均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。
Some improvements of traditional operation of UNITANK process were presented.On the basis of which some key factors such as Hydraulic Retention Time(HRT),Dissolved Oxygen(DO),and Sludge Retention Time(SRT) were investigated to figure out their effects on the treatment effectiveness. The results showed that COD and NH3-N of treated water could reach the first grade of integrated wastewater discharge standard as the system was properly controlled. Proposals have also been put forward on strengthening phosphorous removal in further studies.
