Problems solved by technology

[0003] While the tidal flats with multiple functions such as greening are disappearing in the water-land transition zone, a certain area of ​​land greening projects will be built on hardened stone revetments such as urban rivers and lakes. Although the hard rivers and lakes have green landscapes, water and land The state of isolation and low self-purification ability of water bodies still cannot be changed

Abstract

The invention discloses an unpowered river bank landscape wet land water quality purification system. The system comprises a water inlet pipe, a water distribution ditch and a landscape wet land built on the inner side of a revetment. The water distribution ditch is formed in the tail end of the landscape wet land and is composed of a retaining wall and a bounding wall. The bounding wall is of a brick-concrete structure. A guide wall is arranged on the lower portion of the retaining wall and the upper portion of the retaining wall is a solid wall. The water inlet pipe is embedded into the landscape wet land. The front end of the water inlet pipe penetrates through the revetment and is communicated with a river channel. The center of the cross section of the water inlet pipe is located on the ordinary water level portion and the rear end of the water inlet pipe is provided with a one-way retaining valve and penetrates through the solid wall to be communicated with the water distribution ditch. A plurality of overflow holes are formed in the pipe wall on the upper half portion of the first 1 / 4 section of the water inlet pipe in the landscape wet land. According to the river bank landscape wet land water quality purification system, water quality purifying and band side afforesting of the river channel are combined, the exchange of water in the wet land and water in the river channel is facilitated through waves, the original landscape afforesting function of land afforesting is kept, and the water purification function of the river channel and a lake is improved. Power consumption is not needed, passive unpowered operation is achieved, management is simple and convenient, and the system is durable and stable.

Description

technical field [0001] The invention belongs to the technical field of comprehensive improvement of rivers, and in particular relates to a water quality purification system for unpowered river bank landscape wetlands. Background technique [0002] Over the years, water conservancy projects have focused on flood control and drought relief, river bank safety, and the creation of uniform revetments. Large-scale hardened stone revetments have been built on rivers and lakes, so that the water-land ecotone can provide a good growth environment for various aquatic organisms. The tidal flats with important functions of greening, ecology and water purification have disappeared, and the self-purification ability of water bodies has been greatly reduced. Even in urban landscape lakes and ponds where no point source pollutants are discharged, turbid water landscapes and poor water quality are often present. [0003] While the tidal flats with multiple functions such as greening are disa...
