The invention discloses a microbial inoculant for remediation of heavy metal pollution and its application. The raw materials of the microbial inoculum, in parts by weight, comprise 1-2 parts of Alkali bacteria, 1-2 parts of Bacillus subtilis, 90-100 parts of peptone, 15-20 parts of yeast extract, 0.5-1 part of Ferric phosphate, 30-40 parts of urea, 1000 parts of water, 0.2-0.5 parts of sodium hydroxide. The microbial inoculum of the present invention can be obtained after shaking and culturing the raw material of the microbial inoculum at 37° C. and 120-130 r/min for 18 hours. The microbial inoculant can be used in the remediation of heavy metal pollution in soil or wastewater, cultivate and multiply a large number of water-producing Alkali bacteria and Bacillus subtilis in soil and wastewater, and generate a large amount of bicarbonate by decomposing urea, under the action of soil and Heavy metals in wastewater form carbonate deposits to achieve the purpose of removing heavy metals. |
