| 摘 要： | 以宜兴市华骐污水处理厂的二级出水作为研究对象,研究碳氮比、水力负荷和气水比对复合曝气生物滤池运行的影响。研究发现,以葡萄糖作碳源,当碳氮比6:1时,滤池对总氮的去除率能达到80%以上,出水亚硝酸盐浓度很低。保持碳氮比为6,随着水力负荷的增大,滤池对总氮的去除率会有所下降,但增大到3.5 m/h时,去除率仍保持在60%以上;水力负荷对于浊度和COD的去除率影响不是很大。随着气水比的增大,好氧段对于COD的去除率呈上升趋势。

| Abstract: | A pilot scale experiment was carried out with effluent from secondary treatment of Huaqi Wastewater Treatment Plant in Yixing as research object.The C/N ratio,hydraulic load and the gas-water ratio were investigated to analyze their impacts on combined biological aerated filter(CBAF).The results show that taking glucose as carbon resource with C/N ratio of 6:1,the total nitrogen(TN) removal rate of the biofilters can reach over 80%,and the NO2-concentration in the effluent is low.Maintaining this C/N ratio,... |
