COD浓度和进水流量比对一体化工艺脱氮除碳的影响
Influence of different influent flowrate ratios and COD concentration on carbon and nitrogen removal in integral process
摘要
Abstract
Influence of different influent flowrate ratios(R=Qanaerobic/Qanoxic)and COD concentration on the carbon and nitrogen removal by the integral OCO process with the center-island settling tank was studied when the total influent flowrate from anaerobic zone and anoxic zone remains constant.The COD removal efficiencies do not change obviously at different influent Rs and COD,and the effluent COD is less than 50 mg/L,the COD removal rate is more than 92%.The TN removal efficiencies are decided by Rs and COD.The TN removal effieiencies increase gradually along with reduction of influent Rs when the influent COD is 100 mg/L or 200 mg/L.The TN removal efficiencies increase first and then decrease along with the reduction of Rs when the influent COD is 300 mg/L.The highest TN removal rate is 87% when the influent Rs is 3:1.关键词
