The present invention is achieved in that and sets up an artificial swamp pond, and there is a partition wall middle and upper part, wetland pond, and a water inlet pipe is arranged at the top, one side of partition wall, and a rising pipe is arranged at the other side top of partition wall.Filling filler in the pond, the filler fill order is: bottom filling particle diameter is that the pebbles of 40～80mm is crossed water layer thickness 10～30cm, be that particle diameter is zeolite and the Wingdale mixed fillers of 4～8mm on it, volume ratio is 1: 1, thickness is 50～80cm, the quartzy fine sand layer that particle diameter is 1～2mm is filled out in the shop, top, and thickness is 10～20cm.Plant above the quartzy fine sand layer plant is arranged, various plants bed based on Canna generalis Bailey, between mix with napier grass, calamus and hay grass and to take plantation, planting density be 38～40 strains/square metre, Canna generalis Bailey: napier grass: calamus: its planting proportion of hay grass is 4～8: 1～2: 4～8: 1～2; The root system of plant is deeply to bottom pebbles layer.
Fluidised form adopts vertical compound flow constructed wetland, and to the water inlet of stream cell surface, current direction is flowed to bottom pebbles water conservancy diversion layer, and then flows into the upward flow unit down through the main body packing layer current by down, and current are discharged by its top.
Reach " urban sewage reutilization water for scenic environment use water quality " (GB/T 18921-2002) standard through main water-quality guideline such as ammonia nitrogen, total phosphorus, COD and BOD in the artificial swamp processing back water outlet.
The utility model adopts artificial swamp that effluent of municipal sewage plant is carried out advanced treatment, have that treatment effect is good, processing efficiency is high, the shock resistance compound ability is strong, stable, the investment working cost is low, convenient management, advantage such as both artistic and practical, has development prospect preferably, suitable promoting the use of.Adopt the plant bed vertical combined-flow simulation artificial wet land treating system of Canna generalis Bailey that sewage disposal plant effluent is carried out advanced treatment, can remove pollutents such as nitrogen phosphorus effectively, thereby prevent the eutrophication of water body effectively, its water outlet also can be used for the view reuse.
