摘　　要：实验室条件下,以北方农村模拟生活污水为研究对象,探究在曝气和搅拌两种不同条件下,高效藻类塘对模拟污水中NH4^＋-N、TP和COD的去除作用。研究结果表明,当反应器中藻菌微生物接种量为（2.6-3.5）×10^5个/m L,停留时间7 d时,藻类塘对COD、NH4^＋-N和TP的去除率最高分别可达87.77%、97.2%和64.8%,出水水质可达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）一级A标准。The removal efficiency of ammonia nitrogen,total phosphorus and chemical oxygen demand（ COD）were investigated during the high rate algal pond（ HRAP） process for the treatment of northern rural simulated domestic wastewater under the different conditions of aerating and stirring in abench-scale experiments. The results showed that,When the microbial inoculation of algae and bacteria was（ 2. 6 - 3. 5） × 10^5/ m L and the retention time of 7 days,the removal rate of ammonia nitrogen,total phosphorus and COD can reach 97. 2%,64. 8%,and87. 77%,respectively. The effluent quality was able to meet the ＂ Urban Sewage Treatment Plant Pollutant Discharge Standard＂（ GB 18918—2002） first level A standard.
