摘　　要：为了提高造纸废水的净化处理效果,使造纸厂的出水水质满足工业要求,提出了人工湿地系统在造纸废水净化处理中的应用。选择风车草、富贵竹和芦苇作为人工湿地植物,以无烟煤为主要基质,模拟人工湿地系统净化处理造纸废水。结果表明,与风车草和芦苇相比,富贵竹在人工湿地系统中对造纸废水中COD、总磷、总氮和色度的去除能力都是最好的,将富贵竹与无烟煤组合在一起,可以提高造纸废水中COD、总磷、总氮的去除率,降低造纸废水的色度,通过人工湿地系统中植物与基质的协同作用,能够增强造纸废水中污染物的去除效果,提高造纸厂的出水质量,使其满足工业要求。In order to improve the purification and treatment effect of papermaking wastewater and make the effluent quality of papermaking plant meet the industrial requirements,the application of constructed wetland system in papermaking wastewater purification and treatment was put forward.Windmill grass,Fugui bamboo and reed were selected as constructed wetland plants,and anthracite was used as the main matrix to simulate the purification and treatment of papermaking wastewater in the constructed wetland system.The results show that compared with windmill grass and reed,Fugui bamboo has the best removal ability of COD,total phosphorus,total nitrogen and chromaticity in papermaking wastewater in constructed wetland system.The combination of Fugui bamboo and anthracite can improve the removal rate of COD,total phosphorus and total nitrogen in papermaking wastewater and reduce the chromaticity of papermaking wastewater.Through the synergistic effect of plants and matrix in the constructed wetland system,the removal effect of pollutants in papermaking wastewater can be enhanced,and the effluent quality of paper mill can be improved to meet the industrial requirements.
