摘要:
本文提出微曝气垂直流湿地的概念,并通过柱状模型实验模拟研究了其对云南滇池流域城郊低浓度生活污水的处理效果.测定了模型的氧利用效率,最高为14.04%.在高水力负荷15.29m3/(m2·d)、气水比1:2的条件下,BOD5和NH4-N去除率分别为74.4%和63.5%,出水平均含量分别为4.96mg/L和2.72mg/L.结果说明,微曝气垂直流湿地工艺能满足低浓度生活污水高水力负荷的处理要求,微曝气耗能折价0.04-0.05元/m3.

Abstract:
A concept Aerated Vertical-Flow Wetland is introduced in the text, experimental researches through a pillared unit werecarried out on the performances of treating domestic wastewater in the rural area of Lake Dianchi valley, Yunnan province. Theoxygen transfer efficiency of the experiment device reached 14.04%. And the experiment data showed that, with hydraulic loading as15.29 m3/(m2·d) and airflow-waterflow ratio 1:2, average BOD5 and NH4-N removal respectively reaches 74.4% and 63.5%. The BOD5 and NH4-N values within outflow get to 4.96mg/L and 2.72mg/L. It resulted that, the Aerated Vertical-Flow Wetland Technicswas effective and economical for suburb domestic wastewater treatment with high hydraulic loading.
Key words:  Aerated vertical flow wetland  suburb domestic wastewater  simulating experiment
