摘　　要：试验运用垂直流人工湿地工艺处理生活污水,湿地植物选用酸模(学名:Rumex acetosa Linn),间歇进水。结果表明,当水力负荷为0.012 m3/(m2.d),pH为7.5~7.8时,出水水质最好:COD为10~20 mg/L,NH4+-N约为0.50 mg/L,TP为0.05~0.10 mg/L,浊度为5.68~6.16 NTU。湿地中的植株比自然生长的植株长势好,随着植株的生长,NH4+-N、TP的去除率稳定在95%以上,COD、浊度的去除率提高且分别稳定在80%和90%以上。In this experimental study,the vertical flow constructed wetland is employed to treat domestic sewage,rumex acetosa linn is selected as constructed wetland macrophyte.The experiment is carried out as batch feedings of sewage.The research result shows that when the hydraulic load is 0.012 m3/(m2·d) and the original water s pH is between 7.5 ~ 7.8,the water quality of outflow is best.The COD is between 10 ~ 20 mg/L,the ammonia nitrogen is about 0.50 mg/L,the phosphorus is between 0.05~ 0.10 mg/L and the turbi...
