Shortage of water resources has become one vital problems world widely, so improvement for making more sufficient use urban tailwater is significant issues environmental engineering as well landscaping. With different technologies and various its types, constructed wetlands can be applied to purify lightly polluted water. Urban quality treatment (WQT) wetland an economical efficient infrastruct...
A pesticide runoff event was simulated on two 10 m x 50 m constructed wetlands (one non-vegetated, one vegetated) to evaluate the fate of methyl parathion (MeP) (Penncap-M). Water, sediment, and plant samples were collected at five sites downstream of the inflow for 120 d. Semi-permeable membrane devices (SPMDs) were deployed at each wetland outflow to determine exiting pesticide load. MeP was ...
A highly-loaded constructed wetland (up to 44±21gCODm(-2)d(-1)) was connected to a bioelectrochemical system (BES) to produce hydrogen peroxide for disinfection purposes. The anode delivered a current from the wetland effluent up to 3.5Am(-2) (maximum 62% anodic efficiency) but was limited in the supply of organic carbon. Hydrogen peroxide could be produced in situ in wetland effluent. Producti...
