Embodiment 1
[0041] A soil bioremediation method, the steps are as follows:
[0042] (1) On-site investigation and analysis of oil-polluted soil, including soil pollution degree, pollutants, pollution range, pollution boundary, etc.
[0043] (2) Bacteria culture: According to the analysis results of step (1), the soil purification flora is determined. The flora adopts a liquid fermentation culture method. After the cultivation is completed, it is dried and dehydrated, and the oily substances in the strains are extracted, and the strains are treated with a biofilm. Film-coated to form capsule-type bacteria powder.
[0044] (3) Nutrient solution preparation: determine the use mode of the nutrient solution and calculate the dosage according to the analysis results of step (1), the nutrient solution is composed of the following raw materials in mass percentage:
[0045] Oxygen release agent ORC: 2%;
[0046] 30% hydrogen peroxide: 0.2%;
[0047] Micro-nano bubble particles: 0.5%;
[0048] ...
Embodiment 2
[0062] A kind of soil bioremediation method, step is basically the same as embodiment 1, and nutrient solution is made up of the raw material of following mass percentage:
[0063] Oxygen release agent ORC: 5%;
[0064] 30% hydrogen peroxide: 0.5%;
[0065] Micro-nano bubble particles: 1%;
[0067] Potassium dihydrogen phosphate: 10%;
[0068] Yeast extract: 5%;
[0069] Compound amino acid: 10%;
[0070] Trace element complexes: 10%;
[0071] Water: 48.5%.
Embodiment 3
[0073] A kind of soil bioremediation method, step is basically the same as embodiment 1, and nutrient solution is made up of the raw material of following mass percentage:
[0074] Oxygen release agent ORC: 1%;
[0075] 30% hydrogen peroxide: 0.1%;
[0076] Micro-nano bubble particles: 0.1%;
[0078] Potassium dihydrogen phosphate: 5%;
[0079] Yeast extract: 1%;
[0080] Compound amino acid: 5%;
[0081] Trace element complexes: 5%;
[0082] Water: 77.8%.
