Abstract

The invention relates to a hydraulic power oxygenation constructed wetland, belonging to the technical field of constructed wetland, waterbody ecosystem restoration and sewage treatment. A plurality of monolater modules of the hydraulic power oxygenation constructed wetland are in a stepped shape to construct the hydraulic power oxygenation constructed wetland; and each level constructed wetland is composed of a water intake device, a wetland main body and a water discharging device. The wetlands in the adjacent two layers are linked with a water intake and discharging connection device so asto ensure that the processed waterbody flows through a first level, a second level...nlevel hydraulic power oxygenation constructed wetland successively and is exhausted after carrying out the n numbered level processing. The invention solves the problems of low dissolved oxygen level of constructed wetland matrix, sludge plugging of the matrix, unstable operation and the like, improves microorganism activity of the bed body, and forms a new sewage processing technology with high efficiency, stability, energy saving and perennial operation. The invention is suitable for the aspects of distributed domestic sewage processing, non-point source control, tail water processing of sewage plant, the waterbody ecological restoration engineering and zoology slope protection.

Description

technical field

[0001] The invention relates to a hydraulic oxygen-increasing artificial wetland, which belongs to the technical fields of artificial wetland technology, water body ecological restoration and sewage treatment. Background technique

[0002] With the development of my country's economy and the improvement of people's living standards, the pollution of water bodies by daily life and industrial production is gradually deteriorating and expanding. At the same time, with the development of socialist spiritual civilization and the construction of new socialist countryside, people have higher and higher requirements for environmental quality, especially water environment quality. The water quality improvement of a series of natural rivers, urban inland rivers, natural lakes and lakes in urban parks is urgently needed to be solved, and rural non-point source pollution also urgently needs to be controlled. As an ecological sewage treatment technology, artificial wetla...
