摘要

The combination of facultative biochemical & constructed wetland technology is a newly cost-effective technology treating low concentration domestic sewage. The biochemical Grau second-order kinetic model and the constructed wetland first-order kinetic model were used in this study. Each parameter of the model was gained by a 200m3/d pilot plant, and the correlation between each kinetic parameter was also analyzed using Matlab7.0. When the influent COD is below 200mg·L-1, the HRT of the facultative biochemical unit is 8-9h and the hydraulic loading of the constructed wetland unit is less than 0.8m3/m2·d, the effluent COD of the integrated technology is less than 50mg·L-1, that is the first grade A of the GB18918-2002 standard. Comparing the forecasted COD by the kinetic model with the actual COD, the correlation coefficient is 0.9093 that shown the model is worthy of application.
