title: [Designing cruxes and ecological issues of constructed wetland systems for wastewater treatment].
abstract: Constructed wetland system for wastewater treatment is an important technological mode of economical and high-effective ecological treatment of wastewater, but it is still necessary to develop and perfect in its performance, and in particular, to make a continuous improvement and systematic optimization in its technical parameters. In this paper, the designing cruxes of constructed wetland systems for wastewater treatment at home and abroad were summarily discussed, and the optimal models and most adaptable values for constructed wetland systems were given on the basis of technological parameters such as hydraulic residence time, hydraulic conduction factors, surface loading rate, and engineering-construct design. In the meantime, some ecological methods were recommended to solve the management of wild animals and mosquito problems resulted from the operation of constructed wetland systems for wastewater treatment.
