The invention relates to the field of soil
pollution remediation, and discloses a micro-ecological reconstruction and remediation method for micro-plastic polluted soil, which comprises the following steps: firstly, screening and enriching micro-plastic degradation functional florae which have the advantages of
pseudomonas and bacillus, and the bacillus can secrete
lipase and
protease; the preparation method comprises the following steps: mixing
biomass charcoal prepared by
pyrolysis of corn straws with a functional bacterium suspension for adsorption, and carrying out
sodium alginate-
calcium chloride crosslinking to prepare an immobilized composite repairing agent; applying a repairing agent accounting for 1-5% of the
mass of the soil, uniformly mixing the repairing agent with the soil, regulating the
soil humidity to 20-30% and the carbon-
nitrogen ratio to (15-25): 1, and maintaining the environment temperature of 15-35 DEG C;
microplastics are removed through the synergistic effect of
biomass charcoal adsorption and functional
flora enzymatic degradation, beneficial microorganisms are enriched synchronously, and functional
gene expression is activated; the problems that in the prior art, functional
flora planting is difficult, the degradation efficiency is low, micro-ecological restoration is deficient, and the environmental adaptability is poor are solved.
