- 摘要：A pilot–scale vertical–flow continuous flow reactors (VF–CFR) was investigated for the treatment of rural domestic
wastewater in the cold areas of Northeast China. VF–CFR helps in the creating of aerobic granular sludge
(AGS), which improves the sludge concentration and removal efficiency of pollutants. VF–CFR achieved a high
removal efficiency of Chemical Oxygen Demand (COD), Ammonia Nitrogen (NH3 N), Total Nitrogen (TN) and
Total Phosphorus (TP) with 90 %, 94 %, 75 % and 93 % under the condition of sharp fluctuation of influent
quality and temperature. The high–throughput sequencing analysis of the AGS revealed that Flavobacterium was a
functional bacterium in the AGS process that had the function of heterotrophic nitrification and denitrification.
The field–scale experiment confirmed the superiority of VF–CFR in wastewater treatment efficacy and stability.
During the experiment, the concentrations of COD, TP and NH3–N in effluent at different temperatures were well
met with the first–class A discharge standard of China (GB 18596–2001). However, there was a risk of exceedance
exists in the reduction of TN removal under low temperature conditions.
