| 摘 要： | 针对我国大多数城市污水低碳氮比的水质特点,提出以好氧-低氧淹没式生物滤池对其进行深度脱氮处理.试验过程中,保持好氧段DO为3.5～4.3 mg/L、低氧段DO为0.9～1.1 mg/L,通过调节2段进水分流比、水力停留时间（HRT）、进水碳氮比（C/N）实现深度脱氮效果.进行了3个阶段的试验研究：首先,以低C/N城市污...

| Abstract: | The municipal wastewater in China is characterized by low ratio of carbon to nitrogen,which is the key restrictive factor for effective biological removal of nitrogen.In this study,the aerobic-low DO biofilm process was used for the nitrogen removal of municipal wastewater.By means of adjusting inflow ratios of aerobic section to low-DO section,hydraulic retention time(HRT) and inflow ratio of carbon to nitrogen(C/N),the performances of nitrification in aerobic biofilm section and denitrification in low-DO ... |
