Abstract

The problem of cadmium pollution in the soil of non-ferrous smelting sites needs to be solved urgently. This study investigated the remediation of cadmium pollution in non-ferrous smelting sites using sulphate-reducing bacteria (SRB). The results showed that the leachate concentration of soil cadmium decreased significantly after remediation with SRB compared with the control group. The chemical form analysis of the soil in the control and remediation groups, respectively, after 36 days of reaction, revealed that the cadmium in the remediation group was transformed into a more stable organic matter bound fraction and residual fraction compared with that in the control group, which indicated that the application of SRB could effectively control the migratory transformation of cadmium. The addition of functional microorganisms in soil remediation promoted the increase of biodiversity. The composition of microbial communities in the control and remediation groups differed significantly, and the most abundant genera in the remediation system were Pseudomonas, Maccllibactoroides, and Trichococcus. The continuous addition of sulphate-reducing bacteria enhanced the stable growth of indigenous sulphate-reducing bacteria.
