NOVELTY - Plant pond-bed jointed artificial wetland sewage processing system comprises a pollutant intercepting precipitating pool, a water leading channel, a water inlet flow controller, a water distributing channel, an artificial wet land plant pond-bed treatment system and a water collecting channel, where the artificial wet land plant pond-bed treatment system comprises four grades of plant ponds and beds. A water distributing water level regulator is arranged between each grade. The plant pond and plant bed of each grade are constructed integrally without an isolating wall arranged in between.    USE - Used as a plant pond-bed jointed artificial wetland sewage processing system.    ADVANTAGE - The device: does not require electrical energy and electrical equipment maintenance; has low investment and operation cost, convenient operation, and hence is suitable for sewage processing engineering of rural villages and towns in mountain areas that has no sewage discharge and diffluence and relatively great water inlet flow; and is suitable for advanced processing of the yielded water of sewage disposal plant of villages and towns.    DETAILED DESCRIPTION - Plant pond-bed jointed artificial wetland sewage processing system comprises a pollutant intercepting precipitating pool, a water leading channel, a water inlet flow controller, a water distributing channel, an artificial wet land plant pond-bed treatment system and a water collecting channel, where the artificial wet land plant pond-bed treatment system comprises four grades of plant ponds and beds. A water distributing water level regulator is arranged between each grade. The plant pond and plant bed of each grade are constructed integrally without an isolating wall arranged in between. The bottom face of the plant pond of each grade is 50 cm lower than that of the plant bed. The bottom face of the plant bond and plant bed of each grade is 10 cm higher than the next grade orderly. The bottom face of the plant bed of the last grade is 60 cm higher than the bottom face of the plant pond of the next grade.
