Abstract

The embodiment of the description relates to a method of repairing polluted soil by employing a microbial compound soil repair agent. The method comprises the following steps: collecting soil samplesof preset parts; culturing the soil samples; screening the soil samples to obtain a compound inoculant; carrying out solid fermentation on a solid fermentation material containing low grade rare earthores by using the compound inoculant; after solid fermentation, carrying out microbial leaching and processing the soil repair agent; determining the applying policy of the soil repair agent according to the growth condition of plants in a field soil test process; and then repairing soil in the field according to the applying policy. Therefore, the polluted soil can be repaired effectively by using the microbial compound soil repair agent beneficial to the low grade rare earth ores, and meanwhile, waste ores are prevented from polluting the environment.

Description

technical field [0001] The embodiment of this description relates to the technical field of soil remediation, and in particular to a method for remediating polluted soil using a microbial composite soil remediation agent. Background technique [0002] The Baiyun Obo deposit in Inner Mongolia is a world-renowned super-large Fe-Nb-REE deposit. It is a comprehensive deposit of iron, rare earth, niobium, potassium, fluorine, phosphorus and other elements. The total rare earth reserves are 35 million tons, accounting for about 38% of the world's reserves, is the world's largest rare earth mine. The Baiyan Obo Mine not only has large iron, rare earth and niobium reserves that are rare in the world, but also has huge potash reserves. For example, the potassium-rich slate belongs to the ninth layer (H9) of the upper wall rock of the Baiyun Obo ore body, and is a water-insoluble potassium resource. Studies have shown that the average content of potassium in potassium-rich slate is ...
