Embodiment 1

[0030] Such as figure 1 As shown, an ecological base for sewage treatment includes a plant skeleton 1, an outer covering layer, and an internal filler 2. The plant skeleton 1 is woven from metal wires, and the outer covering layer is artificial turf or artificial turf loaded with heavy metal adsorbents. The coat material imitates the plant shape, and the inner filler is the humus produced by fermenting the litter of plants. Metal wires are used to weave into the form of plants, and the outside of the wires is covered with artificial turf, which looks like a living plant from the outside, and the function of living plants is realized by filling the skeleton with humus fermented from plant litter. The artificial turf comprises a bottom layer and artificial fibers 6 extending from the bottom layer, the bottom layer is made up of a first bottom layer 4 and a second bottom layer 3 that are detachably connected, and a heavy metal adsorbent 5 is filled between the first bottom layer ...

Embodiment 2

[0032] The preparation method of ecological base comprises the following steps:

[0033] with wire or TiO 2 Composite fibers weave into plant-shaped skeletons; TiO 2 The preparation method of the composite fiber is to prepare the titanium dioxide precursor solution by the sol-gel method, and spin the PVP / TiO2 by electrospinning technology. 2 Precursor composite fiber, the precursor composite fiber is calcined at 450°C to obtain TiO 2 Composite fibers.

[0034] Crush the collected litter, add starter, put it into a fermenter to ferment for 34-40 hours, control the fermentation temperature at 70-75°C, and control the humidity at 60-65%. The humus formed after the fermentation of the litter is filled in the inside the skeleton;

[0035] Prepare the outer covering layer, take plastic grids that can be inserted into each other as the first bottom layer and the second bottom layer of artificial turf, take artificial fibers and fix them on the first bottom layer to form lawn gras...

Embodiment 3

[0038] The preparation method of heavy metal adsorbent described in embodiment two, comprises the following steps:

[0039] S1: Soak the litter in NaOH solution for 12 hours, then cook at 60°C for 4 hours, then clip out the leaves and brush off the mesophyll with a brush to obtain the veins of the leaves;

[0040] S2: Take acrylamide and dissolve it in deionized water, then dissolve the above-mentioned prepared veins in it, react for 20 minutes at a temperature of 20°C, then add initiator ammonium persulfate and anhydrous sodium sulfite, and react at 20°C for 8 hours, Wash with acetone after cooling to room temperature, and obtain cellulose grafted polyacrylamide after vacuum drying;

[0041] S3: Take FeCl 3 ·6H 2 O, dissolved in anhydrous ethanol-ultrapure water mixture, adding vitamin grafted polyacrylamide, reacting for 15 minutes, slowly adding sodium borohydride solution dropwise and reacting for 15 minutes, then taking out the solid, passing through ultrapure water, acet...

Abstract

The invention discloses an ecological base for sewage treatment, and a preparation method thereof. The ecological base comprises a plant skeleton, an outer coating layer and an inner filler, the plantskeleton is formed by weaving metal wires, the outer coating layer is a heavy metal adsorbent supported artificial turf, and the inner filler is humus obtained by fermenting plant litters. The ecological base prepared in the invention has the beauty of living plants, can adsorb heavy metals in water, and can be replaced at any time when the adsorption reaches saturation in order to avoid secondary pollution; and the above adsorbing material directly utilizes the network structure of plant veins to increase the adsorption specific surface area, so cellulose has a large adsorption capacity anda high adsorption efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an ecological base for sewage treatment and a preparation method thereof. Background technique [0002] The water environment is one of the basic elements of the environment, an important place for the survival and development of human society, and the most seriously disturbed and damaged area by human beings. The pollution and destruction of water environment has become one of the major environmental problems in the world today. [0003] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds. Heavy metal pollution is different from pollution from other organic compounds. Many organic compounds can reduce or eliminate their harmfulness through physical, chemical or biological purification of nature itself. Heavy metals are enriched and difficult to degrade in the environment. At present, due to the mining, smelting, and proc...
