Method and device for degrading antibiotics by using microbial flora

Abstract

The invention belongs to the technical field of degradation of antibiotics by using microbial flora, and discloses a method for degrading antibiotics by using microbial flora. The method comprises the following steps that: step 1, antibiotic-containing sewage is injected into a sewage filtering device, the sewage enters the lower layer of the filtering device through an activated carbon layer, and sewage solid impurities are retained on the upper layer of the filtering device; 2, the filtered sewage is pumped into a microbial degradation tank, the microbial degradation tank is divided into a plurality of degradation chambers, after the sewage enters the microbial degradation tank, the sewage sequentially stays and is aerated in each degradation chamber added with microbial flora for degrading different antibiotics, and the temperature of the sewage is adjusted according to the habits of the microbial flora so as to be suitable for the degradation reaction of the microbial flora. The invention also discloses a device for realizing the method. With the method and the device adopted,the technical problems that the reaction effect of a complex microbial inoculant and the sewage is poor, and the sewage containing antibiotics has numerous impurities and is difficult to degrade are solved.

Description

technical field [0001] The invention relates to the technical field of microbial flora degrading antibiotics, in particular to a method and device for degrading antibiotics by using microbial flora. Background technique [0002] According to the chemical structure, antibiotics are basically divided into lactams, quinolones, tetracyclines, aminoglycosides, macrolides and sulfonamides. However, my country is a big country in the production and use of antibiotics, so it has relatively serious antibiotic pollution, which has led to an increase in the resistance of various bacteria in the environment. Therefore, it is necessary to treat the sewage containing antibiotics. The existing treatment methods mainly include microbial degradation and oxidation. [0003] In recent decades, the public health, resource utilization and environmental pollution caused by the extensive use of antibiotics have attracted much attention. Due to the advantages of high efficiency, low consumption, ...
