Abstract: As a new treatment technology, constructed wetland plays an important role and has broad prospects in water pollution control and environmental restoration. Its designing artifice is get-ting progress owing its increasing application in wastewater treatment coupling with the increasingly strict water quality standards.From the aspects of hydrodynamics, contaminants degradation dynam-ics and parameters uncertainty, this paper gave a systematic review on the horizontal subsurface flow constructed wetland models, including load approach, regression equation, first-order k-C* model and its reformed forms, and dynamic mechanistic models. Based on the comparison of the assump-tions and methodologies of the models, the intrinsic relationships in the development of horizontal subsurface flow constructed wetland models were analyzed, and the main issues of their application in constructed wetland design were indicated, with the perspectives in this field discussed.
