Method for treating chloramphenicol wastewater by electrochemical reduction oxidization and reactor of method

Abstract

The invention discloses a method for treating chloramphenicol wastewater by electrochemical reduction oxidization and a reactor of the method. The method comprises the following steps: introducing thechloramphenicol wastewater into a cathode chamber of a reactor main body to fully fill the whole reactor main body; carrying out magnetic stirring to start electrochemical treatment; enabling the wastewater to be subjected to reduction reaction in the cathode chamber; conveying the wastewater treated by the cathode chamber into an anode chamber through a connecting pipeline between the cathode chamber and the anode chamber; enabling the wastewater to be subjected to oxidization reaction in the anode chamber, wherein the current density of the oxidization reaction is 10 to 30mA / cm<2>, the staying time of the wastewater in the cathode chamber and the anode chamber is 1 to 2h and the reaction temperature is 10 to 30 DEG C. According to the method disclosed by the invention, the disadvantagesof a single oxidization method that the treatment efficiency on the chloramphenicol wastewater is low and the toxicity of the treated wastewater is high are overcome through a reduction oxidization method; the concentration of the chloramphenicol wastewater can be efficiently reduced through the reactor and the method, the toxicity of the wastewater is reduced and the biodegradability of the wastewater is improved.

Description

technical field [0001] The invention relates to a method for removing highly toxic antibiotic waste water and a reactor thereof, in particular to a method for electrochemical reduction and oxidation treatment of chloramphenicol waste water and a reactor thereof. Background technique [0002] Chloramphenicol (chloromycetin) is a broad-spectrum antibiotic produced by Streptomyces venezuela. Because of its low cost and good antibacterial and anti-infective effects, chloramphenicol is widely used in the treatment of various infectious diseases. Chloramphenicol is a chlorine-containing nitroaromatic compound. Because the benzene ring contains nitro functional groups and the side chain contains chlorine elements, it has strong side effects and toxicity. Mycin can cause various diseases, such as anemia, neuromuscular disorders, etc.; therefore, due to the toxicity and stability of chloronitrobenzene, its residue and accumulation in the environment, and how to reduce or eliminate t...
