摘　　要：利用垂直复合流模拟人工湿地系统对废纸造纸废水进行处理实验研究，植物床选用水葫芦、水花生、芦苇和美人蕉混合栽种，采用鹅卵石、石英砂和碎石为主体填料。结果表明，虽然收割植物对系统处理效果会造成影响，但多层次、多植物配置的植物床确能有效去除污水中的污染物。废纸造纸废水经氧化塘系统处理后的pH值7．2～7．4，BOD5、CODCr、SS平均浓度分别为416mg／L、543mg／L、429mg/L，水力负荷0．053m^3／（m^2·d）的条件下，经人工湿地处理后BOD5、CODCr、SS的去除率分别为94．9％、91．4％、98．0％。系统性能稳定，连续稳定运行12个月，处理后的尾水主要指标达到制浆造纸工业水污染物排放标准，可用于农灌。Integrated vertical-flow constructed wetland was used in this investigation for the treatment of the effluent from the recycled paper mill. Eichhornia crassipes ,Alternanthera philoxeroide, Phragmites communis and Canna indica L. were selected as constructed wetland plants and quartz sand, macadam and cobblestone were used as filler. Results showed that even plants harvesting will affect the treatment efficiency of the system, however the plants bed with multi-layer configuration still can decrease the pollutants effectively. When the pH value of influent was between 7.16 and 7.45; the average contents of BOD5, CODCr and SS were 416 mg/L, 543 mg/L, 429 mg/L, respectively; hydraulic load 0. 053 m^3/（ m^2. d） , the removal rates of BOD5, CODCr and SS were 94.9% , 91.4% , 98.0% respectively. After 10 months operation, the main indexes of the effluent can meet ＂Discharge regulation of water pollutants for pulp and paper industry＂ （ GB 3544-- 2008 ） and can be utilized for irrigation.
