Problems solved by technology

Yang Huiwen, Pan Yufang, Chen Liyan, etc. mentioned the use of activated carbon to adsorb furaltadone in water and its metabolism At 298K, the absorption rates of activated carbon to furaltadone in 60, 80, 100, 120, and 140ppm solutions were 97.7%, 97.6%, 91.5%, 92.6%, and 88.4% in 100 minutes, but the adsorption method existed Limited by the capacity of the adsorbent, the recovery and processing of the adsorbent is cumbersome, the adsorption time is long, it cannot be completely removed, and it is easy to cause secondary pollution, etc.

Embodiment 1

[0022] Select four parts of furaltadone-containing wastewater, the concentration of furaltadone is 1ppm, use an electron accelerator (10MeV / 15kW S-band standing wave electron linear irradiation accelerator, manufactured by the Institute of High Energy Physics, Chinese Academy of Sciences) to generate electron beams to the selected The furaltadone wastewater was irradiated, and the irradiation doses were 4kGy, 6kGy, 10kGy and 13kGy. The irradiated solution was analyzed by HPLC (High Performance Liquid Chromatography, 5μm, 4.6mm×250mm HYPERSIL BDS C18 reversed-phase liquid chromatographic column from Waters, USA), and the decomposition rate of furaltadone in the treated wastewater was obtained. The obtained data are shown in the table 1.

Embodiment 2

[0024] Select four furaltadone-containing wastewater, the concentration of furaltadone is 5ppm, use electron accelerator to generate electron beam to irradiate the selected furaltadone-containing wastewater, the irradiation dose is 4kGy, 6kGy, 10kGy and 13kGy respectively. The irradiated solution was analyzed by HPLC to obtain the decomposition rate of furaltadone in the treated wastewater, and the obtained data are shown in Table 1.

Embodiment 3

[0026] Four parts of furaltadone-containing wastewater were selected, and the furaltadone concentration was 10ppm. The electron beam generated by an electron accelerator was used to irradiate the selected furaltadone-containing wastewater. The irradiation doses were 4kGy, 6kGy, 10kGy and 13kGy respectively. The irradiated solution was analyzed by HPLC to obtain the decomposition rate of furaltadone in the treated wastewater, and the obtained data are shown in Table 1.

Abstract

The invention provides a method for treating furaltadone-containing wastewater. The method comprises the step of treating the furaltadone-containing wastewater by adopting ionizing radiation. The method has the advantages of short treatment time, high removal rate, easiness in operation and no secondary pollution.

Description

technical field [0001] The invention relates to a treatment method for furaltadone-containing wastewater, in particular to a method for treating furaltadone-containing wastewater by using ionizing radiation technology. Background technique [0002] Furaltadone is a synthetic broad-spectrum antibacterial drug with the basic structure of 5-nitrofuran. It is a stable yellow powder, tasteless or slightly bitter, and belongs to nitrofuran drugs. Furan drugs have a wide antibacterial spectrum, 5-10ppm can inhibit a variety of Gram-positive and negative bacteria, 20-50ppm has a bactericidal effect, and has a certain effect on some protozoa and fungi, and its antibacterial effect is not affected by blood and feces , pus and tissue decomposition products, external use has little irritation to tissue, has good antibacterial effect on Escherichia coli and Salmonella, can treat systemic infection, has the advantages of high curative effect and wide antibacterial spectrum, and can be use...
