Embodiment 1
[0039] Example 1: See figure 1 with Figure 7 , a bioremediation method for metal pollution control, including a soil remediation method, the remediation method is
[0040] S1. Use a cultivator to stir the soil layer polluted by heavy metals to a depth of 30cm-50cm;
[0041] S2. Irrigate the soil to be treated in step S1, make it in a flooded state, and keep it in the air for 3-5 days until loose;
[0042] S3. Mix the soil with a thickness of 20-25cm on the surface layer of the soil to be treated evenly with the composite microbial strains, the composite microbial strains include Bacillus megaterium, Bacillus colloid, Serratia marcescens, Pseudomonas aeruginosa and dense For at least one type of Streptomyces spirochetes, an auxiliary treatment device is set up in the treatment area, and a light-transmitting film 5 is laid on the outside of the auxiliary treatment device, so that the space in the auxiliary treatment device is closed to reduce the impact of the external enviro...
