| Popis: | With the gradual maturity of sewage treatment technology, constructed wetlands are increasingly employed to treat sewage. In residential areas where people live, there are concentrated sewage discharges. Therefore, the author proposes constructing several small movable constructed wetlands in the community to treat domestic sewage in the community. A 40 cm× 40 cm model was established to simulate the removal effect of pollutants. The influent concentrations of simulated COD, NH4 +-N, NO3 −, TP are 96.01 mg/L, 18.23 mg/L, 14.13 mg/L, 3.00 mg/L, respectively, and the outlet concentrations are 18.25 mg/L, 5.51 mg/L, 3.12 mg/L, 0.32 mg/L, the removal efficiency reached 80.99 %, 69.78 %, 77.92 %, 89.33 %, with good simulation effect. It provides a theoretical basis for the construction of constructed wetland. |
