Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention discloses an artificial wetland, which comprises a sewage storage tank and a sewage purification tank. The sewage storage tank is communicated with the sewage purification tank through asewage inlet pipe, and a purification water outlet is arranged at the sewage purification tank. Emergent plants are cultivated in the sewage purification tank. The sewage inlet pipe, positioned at one port of the sewage storage tank, is provided with a sewage grid; the sewage grid has a grid plane which forms an inclined angle with a horizontal plane; a solid waste treatment device is arranged inthe sewage storage tank; and the solid waste treatment device comprises a waste salvage mechanism, a buoyancy driving mechanism and a power transmission mechanism. According to the artificial wetland, additional driving equipment is not required to be provided, buoyancy caused for the reason that the water depth height difference generated when sewage flow is sometimes a little larger and sometimes a little smaller is utilized, and solid wastes at the sewage grid are fished under the cooperation of relevant conveying devices, so that blockage phenomenon of the sewage grid is prevented, and sewage can normally pass through.

Description

technical field [0001] The invention relates to the technical field of constructed wetlands, in particular to a surface flow constructed wetland. Background technique [0002] With the rapid development of environmental protection, people have a wide understanding of the function of wetlands. As the "kidney of the earth", wetlands are responsible for the purification and treatment of the earth's natural water bodies. Due to the gradual reduction and disappearance of natural wetlands in cities, artificial wetlands have received more and more attention and development because of their unique advantages. Constructed wetland system water purification technology is a new type of ecological sewage purification treatment method. Its basic principle is to plant specific wetland plants on the constructed wetland filler to establish a constructed wetland ecosystem. When the sewage passes through the wetland system, the pollutants and nutrients in it are absorbed or decomposed by the...
