Embodiment 1

[0013] Example 1: Prepare a solution with a concentration of ofloxacin of 1ppm to simulate ofloxacin-containing wastewater, and 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 Four times of irradiation were carried out, and the irradiation doses were 3kGy, 6kGy, 9kGy and 15kGy respectively. The irradiated water body was analyzed by UPLC-MS / MS, and the removal rate of ofloxacin in the treated water body was obtained, and the obtained data were filled in Table 1 below.

Embodiment 2

[0014] Example 2: Prepare a solution with a concentration of ofloxacin of 5ppm to simulate ofloxacin-containing wastewater, use an electron accelerator to generate electron beams for four irradiations, and the irradiation doses are 3kGy, 6kGy, 9kGy and 15kGy respectively. The irradiated water body was analyzed by UPLC-MS / MS, and the removal rate of ofloxacin in the treated water body was obtained, and the obtained data were filled in Table 1 below.

Embodiment 3

[0015] Example 3: Prepare a solution with a concentration of ofloxacin of 10ppm to simulate ofloxacin-containing wastewater, use an electron accelerator to generate electron beams for four irradiations, and the irradiation doses are 3kGy, 6kGy, 9kGy and 15kGy respectively. The irradiated water body was analyzed by UPLC-MS / MS, and the removal rate of ofloxacin in the treated water body was obtained, and the obtained data were filled in Table 1 below.

Abstract

The invention relates to a method for treating ofloxacin-containing waste water with an electron beam irradiation technology to allow the waste water to directly reach a drinking water standard. The method mainly comprises the steps of performing irradiation treatment on a water body containing an ofloxacin pollutant through an electron beam accelerator irradiation technology to decompose ofloxacin in the water body, and allowing the electron beam accelerator irradiation dose to be below 15kGy. A flocculant is added into the water body and settling and filtration are performed before irradiation treatment of the ofloxacin-containing water body, the treated water body is introduced to a terminal treatment system after the irradiation treatment of the water body, and the settling, filtration and then discharge are performed. The method is used for treating the ofloxacin pollutant in the drinking water body by the electron accelerator irradiation technology, can quickly and effectively degrade ofloxacin in the water body through low-dose irradiation and can completely degrade low-concentration ofloxacin in the water body by 6kGy low irradiation dose, allows the water body to reach the drinking water standard, is easy to operate, and does not produce toxicity or residual harm.

Description

technical field [0001] The invention relates to a method for treating waste water, more specifically the invention relates to a method for treating waste water containing ofloxacin by using electron beam irradiation technology. Background technique [0002] Ofloxacin (OFLO) molecular formula is C 18 h 20 FN 3 o 4 , whose chemical name is (±)-9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-pyrido[ 1,2,3-de]-[1,4]benzoxazine-6-carboxylic acid belongs to quinolones. Quinolones are a large class of synthetic antibacterial drugs with 1,4-dihydro-4-oxoquinoline-3-carboxylic acid structure, which have inhibitory effects on Gram-negative bacteria and positive bacteria, and can directly act on In the bacterial nucleus, inhibit the bacterial DNA gyrase, so that the enzyme cannot introduce nicks on the DNA double strands, destroy the metabolism and reproduction of bacteria, and quickly kill bacteria. Ofloxacin has wide antibacterial spectrum, good absorption, l...
