  • 摘要: 采用"厌氧/生物滤池/潜流人工湿地"组合工艺处理农村生活污水,系统稳定后表现出良好的净污效能,其中TSS、COD和NH4+-N的去除效率分别为97.7%、89.6%和63.3%,但对TN和TP的处理效果相对偏低,仅为26.7%和32.4%。组合工艺中,厌氧池、生物滤池和人工湿地对TSS去除的贡献率分别为35.7%、9.8%和52.1%,对COD去除的贡献分别为22.4%、33.8%和31.3%,对TN去除的贡献5.4%、0.0%和22.0%。生物滤池主要表现为COD和NH4+-N的强化处理,而人工湿地则能有效去除TSS、TP及TN。因此,在保持工艺不变的情况下,需优化工艺运行参数,保持碳源供给与微生物脱氮除磷之间的平衡。
    Abstract: The combined processes of anaerobic tanks, aerated biofilters, and subsurface constructed wetlands (SSFCW) were applied to treat the rural domestic wastewater. The entire treatment performances of for the combined technology and that of each unit were evaluated. The results showed that the processes achieved high removal efficiencies of 97.7% and 89.6% for total suspended solids (TSS) and chemical oxygen demand (COD), respectively, and a moderated removal of ammonium nitrogen (NH4+-N) (63.3%). However, the overall removal efficiencies of total nitrogen (TN) and total phosphorous (TP) were lower, with the results of 26.7% and 32.4%, respectively. During the whole complete process, the contributions percentages of removed pollutants in the anaerobic tank, aerated tank, and SSFCW were 35.7%, 9.8%, and 52.1% for TSS, 22.4%, 33.8%, and 31.3% for COD, and 5.4%, 0.0%, and 22.0% for TN, respectively. Removal processes of COD and NH4+-N mainly occurred in the aerated biofilter while TSS, TP, and TN were reduced in the SSFCW. Thus, operational parameters can be optimized to improve the performance in nitrogen and phosphorus removal.
