| 摘 要： | 针对现有污泥减量技术对氮、磷去除率低的问题,开发了一个具有同步脱氮除磷和污泥减量功能的HA-A/A-MCO工艺.采用该工艺处理校园生活污水,当进水COD为316～407mg/L时,出水COD≤18 mg/L,对COD的平均去除率为96%;将相当于进水量2%的厌氧释磷污泥回流至水解酸化池与原水-并进行水解处理后,大部分污泥转化为溶解性有机物,且主要是VFA(约275 mg/L),为原水中VFA(58 mg/L)的4.74倍,这为后续A~2/O单元进行脱氮除磷提供了充足的碳源.通过考察各反应池出水的三维荧光特性还发现,HA-A/A-MCO系统的各工段对原水中的溶解性有机质(DOM)具有显著的降解作用.

| Abstract: | Due to low removal efficiency of phosphorus and nitrogen by the existing sludge reduction technologies,an advanced process combining sludge reduction and phosphorus and nitrogen removal was developed.It is the hydrolysis acidification-anaerobic/anoxic-multistep continuous oxic(HA-A/A-MCO) process.The results of treating campus wastewater show that when the influent COD is 316 to 407 mg/L,the effluent COD is equal to or less than 18 mg/L,and its removal rate is 96%.When the return ratio of anaerobic P-releas... |
