Embodiment Construction

[0027] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0028] figure 1 The example of the present invention is used to illustrate the surface wet treatment method. The surface flow wetland treatment method mainly achieves the purpose of removing pollutants through the interception of plant stems and leaves, the adsorption and filtration of fillers, the natural settlement of pollutants, and the absorption of plants. Sewage flows horizontally on the upper layer of the filler, and the solid suspended solids are blocked by the filler and plant roots and precipitated. Microorganisms also attach to the filler or the roots, stems and leaves of the plants to perform biodegradation. Pollutants accumulate in the plants, which remove the pollutants from the water.

[0029] The surface flow wetland treatment method mainly includes laying an anti-seepage membrane on the channel of the surface flow we...

Abstract

The invention provides a cascade coupling treatment method for a polluted wetland. In the method, the polluted wetland is treated by combining a surface flow wetland treatment method and an underground flow wetland treatment method. A coupling effect is formed by combining the functional units so as to effectively remove pollutants and improve the ecological environment. The method has the advantages of high treatment efficiency, small investment, low operation cost, low maintenance technology, low energy consumption and wide application range.

Description

technical field [0001] The invention belongs to the technical field of ecological engineering and relates to a cascade coupling treatment method for polluted wetlands. Background technique [0002] Contaminated wetland treatment technology is to fill a certain length-to-width ratio and bottom slope in a depression to form a packing bed, and plant aquatic plants with good treatment performance, high survival rate and strong pollution resistance on the surface of the bed. flora and fauna ecosystem. According to the water flow mode, wetlands can be divided into free surface flow wetlands, subsurface flow wetlands and vertical flow wetlands. According to the main plant forms in the wetland, it can be divided into floating plant system, emergent plant system and submerged plant system. [0003] Contaminated wetland treatment technology dates back to 1903 and was built in the UK to treat sewage. In 1967, the Netherlands developed a new type of surface flow wetland to treat sewa...
