改良型双污泥工艺处理低C/N城市污水
Treatment of Low C/N Urban Sewage by New Type Two-sludge Process
摘要
Abstract
[ Objective ] The research aimed to optimize two-sludge process,and to clear up the problem in this process. [ Method ] Simulated sewage was prepared and treated by new type two-sludge process. Then the qualities of pre-treated and after-treated simulated sewage were determined and compared. [Result]The results showed that in the experiment,the quality of effluent sewage (COD ＜40 mg/L,TN ＜ 15 mg/L,NH3-N ＜3 mg/L,TP ＜0.5 mg/L) can achieve the classⅠ- A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002). [ Conclusion] These results indicated that the new type two - sludge process could not only resolve nitrifying bacteria and phosphorus removal bacteria contradiction between the sludge age problem,and could also be used for dealing with low C/N urban sewage.关键词
