六箱一体化活性污泥工艺对脱氮除磷处理的强化
Enhanced Treatment for Nitrogen and Phosphorus Removal by Six-Tank Integrative Activated Sludge Process (STIASP)
摘要
Abstract
The effect of nitrogen and phosphorus removal of STIASP is investigated by regulating C/N radio in influent and distribution ratio of influent in the anaerobic and anoxic tanks.Results indicate that there is a positive correlation between C/N radio and removal efficiency of nitrogen and phosphorus under experimental conditions.The concentrations of TN and TP in the effluent are 15.52 mg/L and 1.02 mg/L when C/N radio is 4,which carbon source is obviously insufficient.By adding C/N radio to 5 concentrations of TN is decreased to 12.87 mg/L while the concentrations of TP in the effluent is still 0.5～0.6 mg/L.When the C/N radio is higher than 7,the effluent of the system can stably meet the first grade A standards of Urban Sewage Disposal Plant Contamination Integrated Discharge Standard.Utilization efficiency of carbon source can be improved by adjusting C/N radio to 5 and optimizing influent flow rate distribution ratio.The quality of effluent water is better than Standard A of the first class in GB 18918-2002,which the concentration of TN and TP in the effluent are lower than 13.5 mg/L and 0.36 mg/L.Effect of nitrogen and phosphorus removal would be strength when the influent distribution ratio is 2 in anaerobic and anoxic tanks.关键词
