| titleOfInvention | Efficient microbial remediation method for cadmium-polluted sediment |
| abstract | A high-efficiency microbial remediation method for cadmium-contaminated sediments comprises the following steps: step 1, taking natural reservoir sediment to perform enrichment, domestication and amplification culture of SRB to obtain purified SRB bacterial liquid; step 2, restoring Cd pollution sediments by combining the purified SRB bacterial liquid after the expanded culture with nano zero-valent iron; step 3, collecting Cd polluted sediments jointly repaired by using purified SRB bacterial liquid and nano zero-valent iron at intervals; the predominant species types of typical SRBs at the family level in Cd-contaminated sediments for combined remediation include the family sulfophyllaceae, family sulfoenterobacteriaceae, family sulfobacteraceae, family thioreductaceae, and family sulfovibrio. The method is convenient for realizing in-situ repair, and has the advantages of simple and convenient operation, good repair effect, environmental friendliness and the like. The method can enhance the immobilization effect of Cd, quickly reduce the cadmium content of the overlying water, and realize continuous and efficient repair when newly-increased cadmium is continuously polluted in the overlying water environment of cadmium-polluted sediments. |
