NOVELTY - Artificial wetland water body purifying device comprises an artificial wetland tank, where the one end of the side wall of the artificial wetland tank is provided with a water inlet end (1) and other end of the side wall of the artificial wetland tank is provided with a water outlet end (2). The water inlet end and the water outlet end are respectively provided with a water distribution region (4) and a water collection region (3). The particle diameter of the pebble filled is 30-50 mm. The middle part of the artificial wetland pool is a main body filler area.    USE - The device is useful in urban and rural domestic sewage, food industry, slaughtering industry and industrial waste water process for avoiding the water flow streams and dead area.    ADVANTAGE - The device avoids formation of water stream dead zone, and removes contaminants.    DETAILED DESCRIPTION - Artificial wetland water body purifying device comprises an artificial wetland tank, where the one end of the side wall of the artificial wetland tank is provided with a water inlet end (1) and other end of the side wall of the artificial wetland tank is provided with a water outlet end (2). The water inlet end and the water outlet end are respectively provided with a water distribution region (4) and a water collection region (3). The particle diameter of the pebble filled is 30-50 mm. The middle part of the artificial wetland pool is a main body filler area (11) and is divided into five layers filled with different sizes of screened quartz sand. The filling materials are filled in turn from top to bottom is as follows: a first filling layer is filled with quartz sand of particle size 0.1-1 mm; a second filling layer is filled with quartz sand of particle size 0.1-3 mm; a third filling layer is filled with quartz sand of particle size 1-3 mm; a fourth filling layer is filled with quartz sand of particle size 1-5 mm; and a fifth filling layer is filled with quartz sand of particle size 3-7 mm. The wetland emergent aquatic plants are planted on the first filling layer and the emergent aquatic plant is Canna, reed and cattail.
