- Abstract:
- According to the survey, the applications of constructed wetlands (CWs) used to treat effluent from wastewater treatment plants in China has increased rapidly, and it has exploded in the past four years, which may be due to the impact of relevant water environment governance policies issued by the country and various provinces and cities. Most of the 260 CWs were hybrid systems consisting of more than one type of CWs. The vertical subsurface flow system is very effective in the removal of chemical oxygen demand (COD), ammonia nitrogen and total phosphorous (TP), and it is more reliable than the other two systems. Pretreatment systems with enhanced measures, such as aeration and biofilm packing, can effectively remove COD and ammonia nitrogen. In order to achieve better nitrogen and phosphorus removal, integrating intensified nitrogen and phosphorus removal technologies with CWs has been drawing more and more attention and has been successfully applied in many engineering projects.
