Research progress of enhanced hydrolysis in pretreatment of antibiotic production wastewater
Wastewater from antiobitic production contains high concentration of antibiotic,which may affect the treatment performance of bioreactor and accelerate the proliferation and diffusion of antibiotic resistance gene(ARG).Using hydrolysis to pretreat antibiotic production wastewater can break the chemical bond of the antibi-otic,make the functional group fall off,decrease the antibacterial activity of the hydrolysis product,which is ben-eficial to the subsequent biological treatment.Through changing the pH value of the solution and the environment temperature,the hydrolytic process can be accelerated,and then,the enhanced hydrolysis effect is obtained.Based on the analysis of hydrolysis mechanism of different antibiotics,the research progress of enhanced degra-dation of different antibiotics by pyrohydrolysis,acid hydrolysis and alkaline hydrolysis in recent years were sum-marized.
