Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] In Fig. 1, the present invention is made up of bow shed 6 and constructed wetland system. The upper layer of the constructed wetland system is provided with a bow shed 6, on which a bow-shaped non-drip film is laid, and a layer of waterproof paper quilt is added on the non-drip film to enhance the operation effect of the wetland system in winter.

[0023] Constructed wetlands are made of artificially constructed pools or grooves (the pool body is made of bricks and cement), with distribution pools 7 and outlet pools 8 at both ends, an anti-seepage layer laid on the bottom, and water inlet pipes 1 and outlet pipes. The water pipe 2 is a packing layer 3 on it, and it generally forms a packing bed by waste bricks, gravel or mixed packing, and the soil layer 4 of a certain thickness is filled on it, and it is 3 according to the ratio of pastoral soil...

Abstract

The present invention discloses a kind of artificial arched canopy wet land and its application in sewage treatment process. It includes an artificial wet land system and an arched canopy skeleton placed on the artificial wet land system, on its lower layer at least one layer of fogging-resistance film is fixed, and the upper layer of said arched canopy skeleton is a formed from water-proofing paper cover.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an artificial bow shed wetland and its application in sewage treatment technology. technical background [0002] Constructed wetland is a new type of ecological sewage treatment technology that emerged in the 1970s. It is generally composed of matrix fillers, aquatic plants and microorganisms. Through a series of physical, chemical and biological synergies, the efficient purification of sewage is achieved. Constructed wetlands are divided into surface flow constructed wetlands and subsurface flow constructed wetlands according to the different flow patterns of water in the wetland system. Constructed wetlands have the advantages of low construction costs and strong resistance to hydraulic shock loads. However, there are also disadvantages such as the pollutant removal effect is greatly affected by the season, and the area is large. Contents of the invention [0003] In order t...
