Problems solved by technology

Among them, water diversion and water exchange measures require sufficient and convenient clean water sources as water exchange sources. At the same time, this method has disadvantages such as poor water quality stability and pollution transfer; adding chemical or microbial agents has the disadvantages of large capital investment, easy to repeat water quality, and Secondary pollution and other issues; forced aeration measures have the disadvantages of high energy consumption and high treatment costs

Embodiment Construction

[0028] The composition structure, working principle and application method of the device of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] The landscape-type composite artificial wetland treatment device for eutrophic water body of the present invention is built on the bank of a river, lake or reservoir to be treated, and the treated water is eutrophic water body. The device of the invention makes full use of the respective advantages of the surface flow and the horizontal subsurface flow artificial wetland, and while purifying and treating the eutrophic water body, it also improves the surrounding landscape of the wetland.

[0030] Such as figure 1 As shown, a landscape-type composite constructed wetland treatment device for eutrophic water body includes a closed wetland wall 11 isolated from the outside. The top surface of the wetland wall 11 is 0.2m higher than the surrounding ground. The wetland wall 11 is eq...

Abstract

The invention discloses a landscape-type composite artificial wetland treatment device for eutrophication water body and application thereof. The composite artificial wetland mainly comprises a wetland wall, a diaphragm wall, a water inlet distribution channel, surface flow and horizontal underflow artificial wetland units which are in upper and lower superposition and serial connection, a middlemixed tank, a water collecting tank, a water inlet / outlet pipeline, and other units. The composite artificial wetland combines the advantages of the surface flow and horizontal underflow artificial wetland, guarantees engineering treatment effect and fulfills the aim of creating wetland landscapes when treating the eutrophication water body according to different dissolved oxygen environments of the surface flow and horizontal underflow artificial wetland, and has the advantages of small occupied area, high treatment efficiency, low construction cost, low possibility of blockage, high operating stability, excellent landscape efficiency, easy popularization and application, and the like.

Description

technical field [0001] The invention relates to the technical field of sewage treatment by composite constructed wetlands, in particular to a landscape-type composite constructed wetland treatment device for eutrophic water bodies and its application. Background technique [0002] Constructed wetland is a new type of sewage treatment technology developed in the 1970s. After decades of development, this technology has been widely used in the treatment of domestic sewage, surface water, and non-point source pollution. It mainly uses the comprehensive function of wetland plants, microorganisms and soil (or filler) to remove pollutants in sewage. It has the advantages of simple structure, low treatment cost, and landscape effect. [0003] Constructed wetlands are mainly divided into surface flow constructed wetlands and subsurface flow constructed wetlands according to the flow state of treated sewage. Among them, subsurface flow wetlands include horizontal subsurface flow cons...
