Embodiment Construction

[0026] like Figure 1-Figure 2 As shown, the constructed wetland sewage treatment device of the present invention includes a water distribution system 1, a sewage treatment system 2 and a water collection tank 3; the water distribution system 1 is cylindrical, and the sewage treatment system 2 and the water collection tank 3 are both annular cylinders;

[0027] The water distribution system 1 is located in the center of the sewage treatment system 2. The water distribution system 1 and the sewage treatment system 2 have the same height and share the bottom plate 7. The upper ends of the water distribution system 1 and the sewage treatment system 2 are not closed.

[0028] The upper end of the water distribution system 1 is a water inlet 4, and a number of water distribution holes 6 are evenly distributed on the side wall at the bottom of the water distribution system 1. The water distribution holes 6 are connected to the water distribution system 1 and the sewage treatment syst...

Abstract

The invention discloses a constructed wetland sewage treatment device. The constructed wetland sewage treatment device comprises a water distribution system, a sewage treatment system and a dust-collecting tank. The water distribution system is cannular. The sewage treatment system and the dust-collecting tank are annular barrels. The water distribution system is arranged in the center of the sewage treatment system. An end of the water distribution system is a water inlet. A side wall of the bottom of the water distribution system is provided with multiple water distribution apertures. The dust-collecting tank is sleeved on an upper end of the sewage treatment system. An outer wall of the upper end of the sewage treatment system is provided with multiple rows of drainage holes. The waterdistribution system, the sewage treatment system and the dust-collecting tank are concentric circles. The sewage treatment system and the dust-collecting tank are equally divided into multiple fan-shaped treatment units by multiple vertical water-stop sheets. A dust-collecting tank bottom part of each one of the fan-shaped treatment units is provided with a water outlet. The constructed wetland sewage treatment device effectively solves matrix obstruction problems and improves matrix removal performances. Sewage treated by the constructed wetland sewage treatment device can reach standards and is directly recycled or is discharged into water. The constructed wetland sewage treatment device is simple, is convenient for management, needs low capital construction and operation costs, and hasstable treatment effects.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to an artificial wetland sewage treatment device. Background technique [0002] Constructed wetland is an efficient ecological water purification technology with strong nitrogen and phosphorus treatment capacity. It has advanced technology, reliable technology, high efficiency and energy saving, simple operation, low investment, low operating cost, and significant ecological and environmental benefits. It can realize sewage resourceful. It is suitable for the treatment of municipal sewage, industrial and agricultural wastewater and the restoration of polluted water bodies. The treated water can be directly reused or discharged into landscape water bodies, reservoirs, rivers or lakes. Based on the above advantages, the constructed wetland technology has been paid more and more attention. [0003] At present, the infrastructure construction in rural areas is weak, the dra...
