Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing:

[0017] Such as figure 1 Shown, a kind of ecological restoration technique that contains step floating bed, comprises the following steps:

[0018] In the first step, the polluted river water is filtered through the biological protective film of the stepped floating bed, and the suspended particles and floating objects in the water body are intercepted through the biological protective film;

[0019] In the second step, the water body filtered by the biological protective film enters the floating bed action area of ​​the stepped floating bed, and the water quality condition is improved through the biological purification of the stepped floating bed;

[0020] In the third step, the purified water treated by the stepped floating bed passes through the floating bed action area of ​​the stepped floating bed and enters the submerged plant planting area surrounded by the stepped ...

Abstract

The invention relates to an ecological restoration process which is applied to a polluted water region of an urban river channel. In the restoration process, a step floating bed is used as an ecological restoration tool, plants of the step floating bed are distributed in a stepped mode from lower side to upper side and have large distances, and the step floating bed has high sunshine transmittance and an obvious water body purification effect; and submerged plants are overspread in a submerged plant plating region defined by the step floating bed and then is removed from a low layer floating plant region of the step floating bed, so that the submerged plants are gradually spread to a floating bed action region of the step floating bed and are gradually overspread in the whole river channel polluted region to finish the ecological restoration of a polluted river channel. According to the restoration process, a constructed aquatic organism community is used as a main body supplemented with water quality ecological protection technologies such as an ecological revetment technology and the like, and a natural harmony sustainable development concept is fully reflected by a step filter bed system and a sewage body and quality ecological restoration and ecological maintenance technology for supplementing a water quality ecological restoration treatment technology.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an ecological restoration process applied to polluted waters of urban water canals or tributary rivers. Background technique [0002] Nowadays, urban water canals or tributary rivers are facing huge challenges, such as: the urban area is expanding rapidly, but the sewage facilities and sewage treatment systems cannot keep up with the expansion speed; the sewage and sewage of small transport ships are directly discharged into the river; coastal residents, New residents have weak awareness of environmental and ecological protection, etc., which have caused many rivers to be polluted to varying degrees. The water in the rivers is eutrophic and the water self-purification ability is poor. [0003] In recent years, in the construction of urban green spaces, parks and residential quarters, artificial lakes, landscape ponds and landscape pools have emerged continuously....
