Embodiment Construction

[0019] An embodiment of the folded flow constructed wetland system, such as Figure 1-2 As shown, it includes surface wetland 11 and undercurrent wetland 12. The surface wetland 11 and the undercurrent wetland 12 are arranged one above the other and there is a water barrier 13 between them. The water barrier 13 can be made of clay, bentonite or other inorganic Waterproof material. The surface wetland 11 is composed of a planting soil layer and wetland plants set above the water barrier 13, and the subsurface wetland 12 includes wetland filler; in addition, the water source flow direction of the surface wetland 11 is opposite to that of the subsurface wetland 12. A water distribution channel 14 is provided at the downstream end of the surface wetland 11. The water distribution channel 14 is the water distribution channel of the subsurface wetland 12. It has a water distribution wall. When working, the water distribution channel 14 first receives the processed water from the surfa...

Abstract

The invention relates to an artificial wetland for purifying a water source, in particular to a folding-flow artificial wetland system. The system comprises a surface flow wetland, an underflow wetland and a water-resisting layer; the surface flow wetland and the underflow wetland are vertically arranged in a stacked manner; the water-resisting layer is between the surface flow wetland and the underflow wetland; the surface flow wetland and the underflow wetland are opposite in water source flow direction and connected through a water distribution channel; and the water distribution channel is provided with a water distribution tracery wall for distributing a water source treated by the surface flow wetland to the underflow wetland. According to the invention, on the premise of not increasing the area of the surface flow wetland of the original artificial wetland system, the folding-flow artificial wetland system has the effect of treating the underflow wetland, therefore, the purification efficiency of the wetland system on a sewage source is greatly increased in the occupation area, which is the same to that of the current artificial wetland system; the land utilization rate in water treatment occasions is increased, therefore, the folding-flow artificial wetland system disclosed by the invention solves the problems of being too-large in occupation area and low in land utilization rate in the current artificial wetland.

Description

Technical field [0001] The invention relates to an artificial wetland for purifying water sources, in particular to a folded flow artificial wetland system. Background technique [0002] Constructed wetland, also called artificial wetland, is artificially constructed and supervised and controlled, using the triple synergy of physics, chemistry, and biology in the ecosystem, through filtration, adsorption, precipitation, ion exchange, plant absorption, and microbial decomposition. To realize the system of efficient purification and treatment of sewage. General constructed wetland systems have the following characteristics: (1) Low construction and operating costs; (2) Easy to maintain; (3) Effective and reliable wastewater treatment; (4) Ability to buffer the impact on hydraulic and pollution loads; (5) Can produce benefits, such as aquatic products, livestock, papermaking raw materials, building materials, greening, wildlife habitat, entertainment and education. Constructed wet...
