Problems solved by technology

However, pollution interception and treatment can only solve external pollution, while internal pollution still exists, and the ecological functions of rivers still cannot be restored.
[0004] Although people are now trying to restore the ecology of some rivers, the main method is to use the natural growth of submerged plants to treat black and odorous water bodies, but this technology has been used in some urban rivers with shallow water levels in non-flood seasons and high water levels in flood seasons. not applied

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with specific embodiments.

[0033] 1. A sunken river wetland system for river ecological restoration , including a river channel, which is alternately arranged as a pebble shoal area 1 and a sunken planting area 2 along the water flow direction; pebbles are laid in the river bed of the pebble shoal area 1 to form a pebble layer 11 for slowing down the water flow velocity and serving as biofilm matrix and build pebble landscape; the river bed of the sunken planting area 2 is lower than the river bed of the pebble shoal area 1, and there are submerged plants 21 with water purification function planted on the river bed of the sunken planting area 2 , so that the sunken planting area 2 simultaneously constitutes an ecological landscape area.

[0034] The pebble shoal area 1 can be used as a landscape for pebble observation, and can also slow down the speed of water flow during the flood season...

Abstract

The invention discloses a sinking type river channel wetland system for river channel ecological restoration and a construction method thereof.The wetland system comprises a river channel.The river channel is provided with pebble shoal areas and sinking type planting areas, and the pebble shoal areas and sinking type planting areas are alternately arranged along the water flow direction.Pebbles are laid in the river bed of each pebble shoal area to form a pebble layer.The river bed of each sinking type planting area is lower than the river bed of each pebble shoal area, and submerged plants with a water purifying function are planted on the river bed of the sinking type planting area to allow the sinking type planting area to form an ecological landscape area.The construction method includes: designating the pebble shoal areas and the sinking type planting areas in the to-be-constructed river channel, digging the sinking type planting areas according to preset depth, mounting stone cage protecting walls, laying the pebbles, and planting the submerged plants in the sinking type planting areas to form the ecological landscape areas.The sinking type river channel wetland system has the advantages that the system is good in water purifying effect, the growth of the submerged plants is guaranteed during the dry season, and damage of high-speed water flow to the submerged plants can be effectively avoided during the flood season.

Description

Technical field [0001] The present invention belongs to the field of urban water body ecological restoration, which involves a sinking river wetland system and construction method for river ecological restoration. Background technique [0002] In recent years, with the rapid development of my country's economy and excessive development and utilization of water resources, industrial wastewater, agricultural sewage, domestic sewage, and surface runoff water flowed into the river, which caused the river water to deteriorate, and the ecological environment of the river was severely damaged.In addition to exogenous pollution, the endogenous pollution of the river cannot be ignored. The black mud of the river at the bottom of the river has been floating on the water for a long time, especially in summer, the mud floating and smelling, which seriously affects the lives of water and surrounding residents. [0003] At present, the focus of river treatment is to cut off pollution, govern t...
