System for preventing and controlling heavy metals and method for preventing and controlling heavy metals using the same
It discloses a system for controlling heavy metals and a method for preventing and controlling heavy metals using the same. The system includes a constructed wetland (3), in which several layers of fillers are laid, so that water is allowed to flow through each layer of the filler to remove heavy metals. Preferably, a sandwich wall is constructed around the constructed wetland (3), and organic matters (12) which generating heat through fermentation is filled in the sandwich wall to supply heat to the constructed wetland (3) in winter. The sandwich wall is easy to build and the fermentation materials are cheap and easily available, thereby the present method is able to effectively solve the difficulties occurred in the operation of constructed wetland in winter.
