  • Device and method for remedying heavy-metal-polluted soil with microorganism
    Patent number: 11207719
    Abstract: The present disclosure relates to a device and method for remedying a heavy-metal-polluted soil with a microorganism, and relates to a device for remedying a metal-polluted soil and a remediation method thereof. The present disclosure solves the problem that a remediation microorganism cannot be extracted from the soil. The device comprises a main plate and a plurality of microorganism-extracting chambers, wherein the main plate is connected to the microorganism-extracting chambers; the microorganism-extracting chamber are filled with a filler; a tail end of the microorganism-extracting chambers is spiky, and openings are separately provided on a side wall of the microorganism-extracting chambers. The method comprises: I, adding a nutrient medium to the soil, and then inoculating a remediation microorganism; and II, inserting the above device into the soil for 6˜8 days, and then taking it out. The method can remedy heavy-metal-polluted soil in a short time with a high removal rate of the heavy metal.
