The invention provides a practical sludge-discharging and anti-blocking horizontal flow-pushing artificial wetland system which comprises a water feeding pipe, a water distributing channel, a wetlandtreating area, a water collecting channel and a water draining pipe, wherein a plurality of V-shaped sludge-collecting tanks are arrayed at the bottom of the wetland treating area; sludge dischargingpipes are arranged at the centers of the bottoms of the V-shaped sludge-collecting tanks; flow-guiding ventilating back-flushing pipes are arranged along the vertical direction of the sludge discharging pipes; sludge discharging pipe valves are arranged at one end of the sludge discharging pipes and are connected with a sludge discharging channel; the sludge discharging channel is connected with asludge storage tank. The invention utilizes the principle of V-shaped sludge discharging of the settling pond in a sewage treatment plant to establish a novel engineering practical anti-blocking horizontal flow-pushing artificial wetland system, the sludge in the wetland filler can be periodically discharged, the technical problem of easiness in blocking of the artificial wetland filling system can be relieved, the service life thereof can be prolonged, the operation cost can be lowered, the water treatment efficiency can be increased and the ideal treating effect can be achieved. The systemhas the advantages of simple operation, obvious effect, high engineering practical value and convenience in popularization and application.
