Embodiment 1

[0021] This embodiment uses the above-mentioned dedicated device to operate.

[0022] The test object in this embodiment is simulated chloramphenicol wastewater.

[0023] Example 1: Aiming at the simulated chloramphenicol wastewater in the laboratory, the concentration of the chloramphenicol aqueous solution was 100 mg / L, the energy of the accelerator accelerating electrons was 1 MeV, the electron beam intensity was 1 mA, and the treatment time was 20 seconds. After treatment, the residual amount of chloramphenicol was lower than the detection limit (0.010ml / L) and reached the national standard.

Embodiment 2

[0025] This embodiment uses the above-mentioned dedicated device to operate.

[0026] The test object in this example is chloramphenicol wastewater from a veterinary drug factory.

[0027] Example 2: For wastewater from a veterinary drug factory, the energy of the accelerator to accelerate electrons is 1 MeV, the electron beam intensity is 1 mA, and the treatment time is 30 seconds. The residual amount of chloramphenicol after treatment was lower than the detection limit and reached the national standard.

Abstract

The invention relates to a method for radiation treatment of high concentration chloromycetin-containing organic wastewater discharged in the production process of chloromycetin medicament and belongsto the technical field of organic wastewater treatment and environmental protection. The method uses special wastewater radiation treatment devices to degrade chloromycetin molecules in the wastewater through radiation by a high-energy electron beam into harmless small molecules, so that the wastewater can meet the requirements of a national standard for effluent discharge. The method mainly useswastewater treatment devices including an electron accelerator, a wastewater reaction tank and a blower system and uses an aeration device which is a glass sand core arranged in the reaction tank torealize uniform blowing and aeration so as to improve radiation degradation effect of the wastewater under radiation of the electron beam produced in the electron accelerator. The method is simple inprocess, convenient in operation and capable of treating high-concentration refractory toxic organic wastewater with high efficiency and low consumption.

Description

Technical field [0001] The invention relates to an irradiation treatment method for organic wastewater containing high-concentration chloramphenicol discharged during the production process of chloramphenicol drugs, and belongs to the technical field of organic wastewater treatment and environmental protection. Background technique [0002] Chloramphenicol is a cheap, broad-spectrum antibiotic, which is widely used in the treatment of various infectious diseases of humans and animals. Studies have found that chloramphenicol has serious toxic effects on the human hematopoietic system and digestive system, with obvious side effects. After its residue is absorbed by the human body, it will cause gastrointestinal dysfunction and red blood cell reduction. In Annex IV of EU EEC No 2377 / 90, chloramphenicol is listed as a banned drug in animal food production. In my country, it is also included in the Ministry of Agriculture's "List of Banned Veterinary Drugs and Other Compounds for Foo...
