Problems solved by technology

[0004] Patent No. 2018221146702 discloses an artificial aquatic plant for river water purification, which includes a shell, and a planting substrate is fixedly installed inside the shell, and several evenly distributed installation grooves are opened on the top of the planting substrate. The artificial aquatic plants are sewn with strong pearlescent silk thread, and the artificial aquatic plants are fixedly sleeved with grass fiber restraint belts close to the planting substrate. The bottom of the shell is fixed with biological fillers, and the two side walls of the biological fillers and the shell The lower surface is fixedly installed with fixing belts, and two symmetrically arranged buoyancy tanks are installed on the two side walls of the biological filler, and the bottom of the biological filler is fixed with a laterally arranged sleeve through a pipe clip, and the sleeve is fixed on the The jute binding sleeve is socketed, and several identical non-woven fabrics are sewn on the jute binding sleeve, which solves the relatively complicated and difficult problem of artificial aquatic plant installation, but it can be seen from the disclosed content that the above-mentioned prior art It does not solve the problem of degradation of artificial aquatic plants after long-term use, which has caused environmental pollution to a certain extent

Embodiment approach 1

[0029] The above-mentioned water grass fiber 5 is composed of mesoporous activated carbon fibers prepared by mixing asphalt, starch plastic and α-methyl cellulose, and the mass ratio of the pitch, starch plastic and α-methyl cellulose is 4:2:4.

[0030] The preparation method of aquatic plant fiber 5 comprises the following steps:

[0031] (1) Add Y(CH 3 COCHCOCH 3 ) 3 .2H 2 O to obtain yttrium-containing pitch, dissolving starch plastics and α-methylcellulose in DMF to obtain a mixed solution of degradable polymer materials, and spinning out the mixed solution of yttrium-containing pitch and degradable polymer materials through dry jet wet spinning mixed fibers;

[0032] (2) Mesoporous activated carbon fibers were obtained from the mixed fibers through insolubilization, carbonization and activation. The carbonization conditions were as follows: in nitrogen flow, the temperature was raised to 900° C., and the heating rate was 10° C. / min.

Embodiment approach 2

[0034] The above-mentioned water grass fiber 5 is composed of mesoporous activated carbon fibers prepared by mixing asphalt, starch plastic and α-methyl cellulose, and the mass ratio of the pitch, starch plastic and α-methyl cellulose is 5:3:2.

[0035] The preparation method of aquatic plant fiber 5 comprises the following steps:

[0036] (1) Add Y(CH 3 COCHCOCH 3 ) 3 .2H 2 O to obtain yttrium-containing pitch, dissolving starch plastics and α-methylcellulose in DMF to obtain a mixed solution of degradable polymer materials, and spinning out the mixed solution of yttrium-containing pitch and degradable polymer materials through dry jet wet spinning mixed fibers;

[0037] (2) Mesoporous activated carbon fibers were obtained from the mixed fibers through insolubilization, carbonization and activation. The carbonization conditions were as follows: in a nitrogen flow, the temperature was raised to 950° C., and the heating rate was 10° C. / min.

Embodiment approach 3

[0039]The above-mentioned water grass fiber 5 is composed of mesoporous activated carbon fibers prepared by mixing asphalt, starch plastic and α-methylcellulose, and the mass ratio of the asphalt, starch plastic and α-methylcellulose is 6:3:1.

[0040] The preparation method of aquatic plant fiber 5 comprises the following steps:

[0041] (1) Add Y(CH 3 COCHCOCH 3 ) 3 .2H 2 O to obtain yttrium-containing pitch, dissolving starch plastics and α-methylcellulose in DMF to obtain a mixed solution of degradable polymer materials, and spinning out the mixed solution of yttrium-containing pitch and degradable polymer materials through dry jet wet spinning mixed fibers;

[0042] (2) Mesoporous activated carbon fibers were obtained from the mixed fibers through insolubilization, carbonization and activation. The carbonization conditions were as follows: in a nitrogen flow, the temperature was raised to 1000° C., and the heating rate was 10° C. / min.

Abstract

The invention relates to the technical field of water ecological environment protection and ecological restoration, in particular to a bio-based artificial aquatic plant. The bio-based artificial aquatic plant comprises an aquatic plant carrier and a plurality of bundles of aquatic plant fibers arranged on the aquatic plant carrier, wherein the aquatic plant carrier comprises a fixed frame, in which a connecting net is arranged; connecting pieces are arranged at the bottoms of the aquatic plant fibers and fixed by crossing at least one mesh, and the connecting pieces are connected with a fixednet through binding belts; and the aquatic plant fibers are composed of mesoporous activated carbon fibers prepared by mixing blended asphalt, starch plastic and alpha-methyl cellulose. According tothe bio-based artificial aquatic plant, the aquatic plant fibers and the connecting net are connected through the connecting pieces, the efficiency of mounting and dismounting of the aquatic plant fibers and the efficiency of adjusting the distance between the adjacent aquatic plant fibers are higher, and the efficiency of mounting and dismounting of the aquatic plant fibers is effectively improved; a polytetrafluoroethylene material can prevent the carrier from rusting or being corroded in water for a long time, and the service life of the connecting net and the fixed frame is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of water body ecological environment protection and ecological restoration, in particular to a bio-based artificial aquatic plant. Background technique [0002] In the water body, the pollution is aggravating, the growth of aquatic animals and plants is difficult, the self-purification ability of the river is low, the degree and scope of the eutrophication of the water body are developing day by day, and some rivers even have the phenomenon that the water body is smelly, green, and black. However, water purification bacteria have the characteristics of sedentary life, and there must be places that can provide attachment, shelter and bait. Many water purification bacteria cannot reproduce before finding a suitable carrier, and cannot use ammonia and nutrient sources. However, water purification bacteria are in There is a life cycle in a body of water. If only bacteria are allowed to live in the water body, i...
