Analysis on impact of shallow surface flow constructed wetland on removal of organics and total phosphoru

Abstract

In shallow surface flow constructed wetland constructed in the laboratory, with domestic sewage as the study object, the optimum hydraulic load and the relation between removal of organics / total phosphorus and dissolved oxygen of the system is discussed. The optimum hydraulic load for operation of the system obtained by experimental analysis is 0.2m3/m2.d, and the relation between dissolved oxygen and removal of organics is more general than the relation between dissolved oxygen and removal of total phosphorus.
