Abstract:
考察了游离亚硝酸(FNA)预处理对污泥解体和剩余污泥发酵同步反硝化性能的影响.结果表明,不同FNA浓度(0,0.68,1.35和2.03mg N/L)处理剩余污泥预处理过程中,SCOD的产量和产生速率均随着FNA浓度的增加而增加,其中SCOD的产生速率依次为0.66,1.70,2.13和2.70mg/(g VSS?h).随着预处理过程中FNA浓度的增加,剩余污泥中死菌占总菌的比例由41%上升至80%.FNA预处理可使剩余污泥发酵同步反硝化系统SCOD的产量增加49%和污泥减量提高41%,同时使系统反硝化能力提高40%.此外,FNA预处理可使该系统中温室气体N2O产量占NO2-还原量的百分比减少...
