| 摘 要： | 污泥消化液为高氨氮、低C/N比、低碱度的废水,用传统生物脱氮方法处理消化液,存在碳源和碱度不足的双重障碍.本实验在“A/O+SIFEDEN”组合系统中,首先在A/O反应器中实现消化液短程硝化,其出水与初沉污泥在SIFEDEN中同步实现消化液短程脱氮和污泥减量,消化液的TN去除率可达87%,MLVSS去除率为49%左右.考察了SIFEDEN反应器中污泥发酵和污水反硝化的互惠关系、pH值的变化规律等.该系统出水回流到污水厂主流区,不会降低进水C/N,污水厂的脱氮除磷效率得以提高. |

| Abstract: | External carbon source and alkalinity need to be supplied for nitrogen removal from digestion liquid with high concentrations of ammonia,low C/N ratio and low concentrations of alkalinity by traditional nitrogen removal technologies.In this investigation,a novel system consisted of an A/O reactor and SIFEDEN(SImultaneous FErmentation and DENitrification) reactor was used for nitrogen removal from digestion liquid.Firstly,nitritation of digestion liquid was finished in the A/O reactor.Secondly,nitrite and ni... |
