Abstract

With the widespread use of antibiotics, environmental hazards caused by antibiotics and resistant bacteria residues have attracted wide public attention. In this paper, fluorescence quantitative PCR was used to detect and analyze the removal, distribution and influencing factors of four sulfonamide antibiotic resistant genes (sul1,sul2,sul3,sulA) from sludge accumulated in Reed bed of sludge drying at loading stage. The results showed that there was significant difference in abundance of four sulfonamide resistant genes in the accumulated sludge, the average absolute contents were 1.61*108copies/g, 1.04*108copies/g, 4.31*105 copies/g, and 1.22*106copies/g respectively. The accumulation level of resistant genes in the bottom layer of sludge was lower than that in the surface layer, and the root environment of reed was favorable to the removal of resistance genes.
