Problems solved by technology

The advantage of the chemical treatment method is that the operation cycle is short and the oxidation is relatively thorough. This method is also more suitable for the treatment of pollutants with relatively high concentrations. However, secondary pollution is easy to occur after chemical oxidation treatment, and the cost of chemical oxidation High, poor applicability, which greatly limits its application in the treatment of environmental pollutants

[0026] The preparation and application steps of gac of the present invention are as follows:

[0027] 1. Preparation of activated carbon (AC) material

[0028] (1) Pretreatment of walnut shells: wash walnut shells with water to remove ash and gravel, put them in an oven and dry them at 80-85°C for 48 hours, and crush them to a particle size of 40-120 mesh to obtain walnut shell powder, which is stored in a desiccator spare.

[0029] (2)H 3 PO 4 Preparation of dipping material: Accurately weigh 5g of walnut shell powder that has been pulverized by a pulverizer and put it in a beaker, add 25mL of H 3 PO 4 solution, H 3 PO 4 The ratio of walnut shell to mass is (1~4):1. After fully stirring, seal it, soak it in an oven at 90~95°C for 14.5~15.5h, remove the seal, dry it in an oven at 120~125°C for 12~13h, and stir it loosely. For example, stir once every 2 to 3 hours; after drying, H 3 PO 4 Dipping material.

Embodiment 1

[0041] Preparation of activated carbon: Accurately weigh 5g of walnut shell powder that has been pulverized by a pulverizer and place it in a beaker, add 25mL of H 3 PO 4 solution, H 3 PO 4 The mass ratio of walnut shell to walnut shell is 4:1, fully stirred and then sealed, dipped in an oven at 90°C for 15 hours, removed the seal, dried in an oven at 120°C for 12 hours, and stirred every 2 hours to loosen, and after drying, H 3 PO 4 Dipping material. H 3 PO 4 The impregnated material is moved to the constant temperature section of the tube-type atmosphere furnace, and the temperature is raised to the experimentally set carbonization temperature of 250°C at a rate of 10°C / min. ℃, keep warm for 60min, after the reaction is completed, in N 2 Protect and cool down to room temperature to obtain the activated material, transfer the activated material to a conical flask, add 50mL of 1% HCl solution in mass concentration, place on a shaker and vibrate at 120r / min for 180min fo...

Embodiment 2

[0047] In the preparation of H 3 PO 4 Dipping process, H 3 PO 4 The mass ratio to the walnut shell is 2:1, and other conditions and steps are the same as in Example 1 to obtain the target product activated carbon B.

[0048] The target product activated carbon B is used to carry out adsorption treatment and adsorption-catalysis synergistic treatment on acesulfame, the conditions and steps are the same as in Example 1, the removal rate of acesulfame is calculated, and it is found that when only adsorption, the adsorption rate is 27.99%. Adsorption-catalysis When they work together, the degradation rate is 41.67%.

Abstract

The invention relates to a method for removing treatment of antibiotic sulfacetamide by means of activated carbon materials. The method comprises the steps that an activated carbon and hydrogen peroxide solution is added to a sulfacetamide solution, wherein the ration of sulfacetamide to activated carbon to hydrogen peroxide is 0.3875 micromole to 6-7.5 mg to 8-12 micromoles; then the mixture is treated at room temperature for 20-100 min, and the removing treatment of the antibiotic sulfacetamide is completed. According to the method for removing treatment of the antibiotic sulfacetamide by means of the activated carbon materials, the activated carbon materials are adopted, the synergistic catalytic action can be achieved with the hydrogen peroxide, and the antibiotic sulfacetamide is removed; in the removing treatment process, the problems such as secondary pollution caused by a chemical method and high cost can be avoided, and operation is easy. According to the treatment method, only the activated carbon materials need to be added to the sulfacetamide solution at the room temperature, and the industrial treatment steps are greatly simplified; meanwhile, the activated carbon materials are convenient to recycle, suitable for industrial application and especially suitable for the industrial removing treatment of the antibiotic sulfacetamide.

Description

【Technical field】 [0001] The invention belongs to the technical field of antibiotic waste water treatment, and in particular relates to a method for removing and treating antibiotic acesulfame by activated carbon materials. 【Background technique】 [0002] Antibiotics refer to organic substances produced by organisms (plants, animals or microorganisms) in the course of life or obtained from the outside, which can selectively affect or inhibit other biological activities at low concentrations. Antibiotics occupy an important position in the field of medicine because of their unique efficacy. It ranks third in the amount of human medical drugs used, accounting for more than 6% of the total prescription drugs, and more than 70% of the amount of veterinary drugs. Among them, my country is a big country in the production and use of antibiotics. Antibiotics have the characteristics of poor volatility, low vapor pressure and low hydrophobicity, so their transfer in the environment ...
