Problems solved by technology

[0007] However, in practical application of these methods, the compatibility between the carrier or filler grafted with anthraquinone compound and industrial wastewater is not good. After research, it is found that the reason is the hydrophilicity of the surface of the carrier or filler grafted with anthraquinone compound. Low, which limits its compatibility with azo dyes, nitrates, etc. in industrial wastewater, and also affects the compatibility with degrading bacteria

Embodiment 1

[0038] Add 7 parts of 3-(2,3-glycidoxy)propyltrimethoxysilane to 100 parts of alcohol aqueous solution with a volume ratio of 95:5, stir for 0.5 hours, add 25 parts of talc powder with an average particle size of 10 μm, and stir For 1 hour, heat up to 60°C, continue to react for 0.5 hours, filter, filter out the solid, wash it 3 times with absolute ethanol, and dry to obtain epoxy-modified talc powder; the epoxy-modified talc powder is measured by titration. The group content was 0.55 mmol / g.

[0039] Add 100 parts of the above-mentioned epoxy-modified talc powder to 500 parts of tetrahydrofuran, add 9.82 parts of 2-aminoanthraquinone and 0.3 parts of triethylamine, stir for 3 hours, and continue to add 2.2 parts of PEG-NH 2 -200, stirred for 1.5 hours, filtered, the filtered solid was washed three times with absolute ethanol, and dried to obtain hydrophilic talc powder 1 modified with anthraquinone compound.

Embodiment 2

[0043] Add 100 parts of epoxy-modified talc powder in Example 1 to 500 parts of tetrahydrofuran, add 8.6 parts of 2-aminoanthraquinone and 0.2 parts of triethylamine, stir for 3 hours, and continue to add 3.3 parts of PEG-NH 2 -200, stirred for 1.5 hours, filtered, the filtered solid was washed three times with absolute ethanol, and dried to obtain hydrophilic talc powder 2 modified with anthraquinone compound.

[0044] It is measured that the anthraquinone content on the anthraquinone compound-modified hydrophilic talc powder 2 is 0.33 mmol / g, and the polyethylene glycol content is 0.14 mmol / g.

Embodiment 3

[0046] Add 100 parts of epoxy-modified talc powder in Example 1 to 500 parts of tetrahydrofuran, add 11 parts of 2-aminoanthraquinone and 0.3 parts of triethylamine, stir for 3 hours, and continue to add 1.1 parts of PEG-NH 2 -200, stirred for 1.5 hours, filtered, the filtered solid was washed three times with absolute ethanol, and dried to obtain anthraquinone compound-modified hydrophilic talc powder 3.

[0047] It is measured that the anthraquinone content on the anthraquinone compound-modified hydrophilic talc powder 3 is 0.43 mmol / g, and the polyethylene glycol content is 0.04 mmol / g.

Abstract

The invention belongs to the field of water treatment, and relates to the field of treatment of pollutant-containing wastewater, in particular to a preparation method and application of an anthraquinone compound modified hydrophilic carrier. Inorganic filler, plastic and other carriers subjected to hydrophilic treatment react with an epoxy silane coupling agent to obtain an epoxy modified carrier,then an epoxy group and an amino-containing anthraquinone compound are used for reacting with an amino-terminated polyethylene glycol, and an anthraquinone compound and polyethylene glycol modified carrier is obtained, wherein the anthraquinone compound accelerates biodegradation of azo dyes, nitrate and the like, and the hydrophilicity of the polyethylene glycol can improve the compatibility ofthe carrier and the water containing the azo dyes, the nitrate and the like, so that the performance of the anthraquinone compound is further improved. The obtained anthraquinone compound modified hydrophilic carrier can be widely applied to sewage treatment.

Description

technical field [0001] The invention relates to the field of water treatment engineering, in particular to a preparation method and application of an anthraquinone compound-modified hydrophilic carrier. Background technique [0002] Azo dyes have bright color, high color fixation rate and good color fastness, and are widely used in the printing and dyeing industry, but the wastewater produced poses a great threat to the ecological environment and human health. Traditional treatment methods including coagulation-flocculation, membrane treatment, and chemical adsorption cannot completely eliminate the pollution of azo dyes, and are likely to cause secondary pollution. [0003] Nitrate is another class of chemical substances that are harmful to humans and the environment. Ammonia nitrogen and nitrate nitrogen contained in excessively applied chemical fertilizers, domestic sewage, feces, and industrial sewage enter the natural environment through soil and water bodies, and are ...
