specific Embodiment approach 1

[0037] Specific implementation mode one: the artificially strengthened ecological bed water restoration method described in the present implementation mode is carried out according to the following steps:

[0038] 1. Select the polluted natural water body area;

[0039] 2. Build an enhanced ecological bed in the slow flow area of ​​the polluted natural water body area. The enhanced ecological bed is composed of matrix material, filling material and plants. First, the matrix material and filling material are uniformly mixed through a drum mixer to obtain The mixture of matrix material and filling material, and then the mixture of matrix material and filling material is added to the slow flow area of ​​the polluted natural water body area, and then the plants are planted on the mixture of matrix material and filling material, or the plants are planted in the On the mixture of matrix material and filling material and the soil around the polluted natural water body area, the artif...

specific Embodiment approach 2

[0048] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the plants described in step two are canna, calamus, dry umbrella bamboo, reeds, cattails, water onions, rushes, reliflower, and quinces , black algae, bitter grass, bamboo leaf eye vegetable and foxtail algae or a combination of several of them. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0049] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step two, when there is no fixed object around the slow-flow area of ​​the polluted natural water body area, it is necessary to use it around the enhanced ecological bed Barbed wire fixed. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a repairing method for the water body of an artificial reinforced ecological bed, and relates to the water body repairing method. The invention aims to solve the problem that in an existing repairing method, the biocompatibility of used materials is poor, the attaching quantity of microorganisms in a system is limited, the adsorption efficiency of pollutant treatment is low, the occupied area is large, plants are difficult to harvest, and blocking exists. The method comprises the following steps: constructing a reinforced ecological bed in a slow-flow area of a pollutednatural water body area, wherein the reinforced ecological bed is composed of a matrix material, a filling material and plants; or uniformly mixing the matrix material with the filling material, thenadding the mixture of the matrix material and the filling material to the slow-flow area of the polluted natural water body area or alternately laying the matrix material and the filling material onthe slow-flow area of the polluted natural water body area in a layering mode, and then planting the plants. The method provided by the invention is used for repairing the water body of the artificialreinforced ecological bed.

Description

technical field [0001] The invention relates to a method for restoring a water body. Background technique [0002] Constructed wetland is an ecosystem technology that simulates nature originated in the late 1970s. It mainly relies on the biochemical action of microorganisms and plants to remove pollutants. Traditional constructed wetlands usually use local materials and use soil, sand, and gravel as substrates. The adsorption capacity is poor, the ability to transmit oxygen and the ability to attach microorganisms are limited, and the pollutants are mainly removed through filtration, sedimentation and plant absorption, so the treatment is not good. [0003] The traditional strengthening method is to use fly ash, zeolite, steel slag and other materials to mix in a certain proportion to replace the traditional constructed wetland matrix to strengthen its treatment effect. Compared with traditional soil and gravel, its porosity and specific surface area are larger, which improv...
