Embodiment 1

[0017] refer to Figure 1-2 , a kind of ecological floating bed provided by the present embodiment includes a planting basket 1, a substrate 4, aquatic plants 5 and floating balls 3. The planting basket 1 is made of bamboo strips and is cube-shaped, with a size of 60cm×60cm×40cm (in other embodiments, a planting basket 1 of suitable size can be prepared according to actual needs), and its side walls and bottom are meshed. shape, and the pore size of the mesh is 0.1cm. A connecting hole 2 is provided on the top of the side wall of the planting basket 1, and a plurality of planting baskets 1 can be connected together through the connecting holes 2 by using items such as ropes to form a larger planting area. The side wall of the planting basket 1 is connected with the floating ball 3 through a rope, and the floating ball 3 is a polypropylene hollow floating ball. The quantity of floating ball 3 can be determined according to the overall weight of planting basket 1, matrix 4 and...

Embodiment 2

[0023] An ecological floating bed provided in this embodiment includes planting baskets, substrates, aquatic plants and floating balls. The planting basket is made of bamboo strips and is cube-shaped with a size of 60cm×60cm×40cm. Its side walls and bottom are mesh-shaped, and the diameter of the mesh is 0.1cm. A connecting hole is arranged on the upper part of the side wall of the planting basket, and a plurality of planting baskets can be connected together through the connecting holes by using items such as ropes to form a larger planting area. The side wall of the planting basket is connected with the floating ball through ropes, and the floating ball is a polypropylene hollow floating ball. The quantity of floating balls can be determined according to the total weight of the planting basket, substrate and aquatic plants, etc., so as to ensure that the planting basket can float on the water surface or sink into the required depth in water as required. Untie the cord to re...

Abstract

The invention relates to the technical field of ecological engineering and water treatment, and particularly relates to an ecological floating bed and a method for purifying a water body. The substrate in the ecological floating bed consists of magnesium slag ceramic filter balls, bentonite particles and zeolite. The ecological floating bed belongs to a porous inorganic material, has the characteristics of developed micropores, high mechanical strength, good adsorption performance and the like, can be used for effectively adsorbing organic matters and partial inorganic matters in the water body, has relatively strong microbial affinity, and is advantageous to microorganism growth and reproduction to improve the biofilm culturing efficiency of microorganisms, so that the water body purification effect can be improved. According to the ecological floating bed, a planting basket can sink into the water body and float on the water surface periodically, so that the substrate can be alternately located in an aerobiotic environment and an anoxic environment, growth and reproduction of aerobiotic microorganisms and anoxic microorganisms can be facilitated, organic matters in the water body can be well decomposed, and nitrogen and phosphor in the water body can be removed. The ecological floating bed is capable of effectively playing effects of the porous substrate, aerobiotic microorganisms, anoxic microorganisms and aquatic plants, and the purification efficiency of the ecological floating bed can be remarkably improved.

Description

technical field [0001] The invention relates to the technical fields of ecological engineering and water treatment, in particular to an ecological floating bed and a method for purifying water. Background technique [0002] Bioremediation technology is an emerging environmental biotechnology in recent years, which has been widely used in lake restoration projects. The ecological floating bed purification technology with higher plants as the main body is more and more used in the treatment or restoration of eutrophic water bodies due to its advantages of low cost, easy maintenance, and good landscape effects. However, when the existing ecological floating bed technology is applied to practical projects, there are still problems such as immature and stable technology, single technical means, and unpredictability of effects. The decontamination ability of the ecological floating bed is easily limited by the season and the amount of plants in the floating bed, and the purificat...
