| 摘 要： | 采用潜流人工湿地处理农村生活污水,考察了该工艺对COD、BOD5、NH3-N、TN和TP的去除效果。结果表明,湿地对COD、BOD5、NH3-N、TN和TP的去除效果较好,平均去除率分别达到87.4%、83.5%、63.8%、57.9%和90.1%,出水COD为11.2～23.3 mg.L-1,出水BOD5为6.7～11.3 mg.L-1,出水NH3-N、TN、TP的质量浓度分别为10.3～16.1、18.8～23.2、小于1.0 mg.L-1,出水水质优于GB 5084-2005要求。植物种植状况、温度变化及进水污染物含量等因素对湿地处理效率有较大影响,总体上来讲,温度大于20℃、植物种植密度越大、进水污染物含量越低处理效果越好。 |
| 关 键 词： | 潜流人工湿地 农村生活污水 农田灌溉水质标准 |

| Abstract: | The subsurface flow constructed wetland was applied for treatment of rural domestic sewage.The removal efficiencies of COD,BOD5,NH3-N,TN and TP in the process were investigated.The result showed that the removal process may achieve better removal efficiencies of COD,BOD5,NH3-N,TN and TP.The average removal efficiencies of COD,BOD5,NH3-N,TN and TP in the process were 87.4%,83.5%,63.8%,57.9% and 90.1% respectively.The effluent COD was about 11.2～23.3 mg·L-1,BOD5 was about 6.7～11.3 mg·L-1,NH3-N was about 10.3～16.1 mg·L-1,TN was about 18.8～23.2 mg·L-1 and TP was less than 1.0 mg·L-1.It was better than that of standards for irrigation water quality(GB 5084-2005).Plant grow density,temperature variation and influent water concentration had obvious effects on treatment efficiency.In general,when the temperature was greater than 20 ℃,grow density was higher and influent water concentration was less,the treatment efficiency was high. |
