Abstract

The invention discloses a microorganism and PRB combined remediation system and application thereof in in-situ remediation of underground water polluted by antibiotics. The microorganism combined PRB remediation system is of a three-layer structure, the modified kaolin-biochar active filler layer and the modified biochar filler layer are arranged on the two sides, the microorganism filler layer is arranged on the middle layer, and the system can achieve efficient adsorption and degradation of antibiotics in underground water to enable the underground water to reach the underground water remediation standard, can prevent blockage, and has the advantages of being long in service life, low in cost and the like. The continuous degradation of pollutants such as antibiotics in underground water can be realized, and the method has a very wide application prospect.

Description

Technical field [0001] The invention involves a antibiotic pollution groundwater repair system, which specializes in a microbial combined PRB repair system, and also involves a method of repairing antibiotic pollution groundwater in a microbial combined PRB repair system, which belongs to the field of groundwater management. Background technique [0002] Antibiotics are a type of chemicals that have the function of killing or inhibiting his species (mainly microorganisms) that are killed or inhibited during the metabolic process of fungal, picked bacteria, and bacteria. Five categories of tetracycline, rinomycin, and chloramphenicol can play a role in inhibitory, antibacterial and sterilization to varying degrees. Over the past few decades, due to the frequent use and continuous entering the environment, there has been a large accumulation of antibiotics in the environment. Research in recent years has shown different concentrations of antibiotics such as soil, surface water, and...
