Abstract

The invention relates to Pseudomonas fluorescens N1 and a utilization method of the Pseudomonas fluorescens N1 in solid waste resource utilization in combination with microorganisms and full bionic simulation, and belongs to the technical field of biological fermentation and soil remediation. The light, temperature, gas and heat conditions of cyclic conversion of organic carbon in soil are simulated, solid waste is mixed and stacked in the soil or between mountains, basic mixing is performed according to the carbon-nitrogen ratio, the acid-base property and the water content of the solid waste, according to the anaerobic fermentation principle, pile turning is not performed, high-carbon, high-salt, alkaline or acidic waste liquid is introduced through a bionic cover head in the composting process, and the organic carbon in the soil can be recycled. The anaerobic fermentation process is controlled to stop at an acid production stage, so that the produced organic acid and the solid waste are fully and uniformly mixed, and nutrient substances in the solid waste are released by using acidic substances, so that nutrient elements chelated by the acidic substances are formed, and finally, the purpose of resource utilization of the solid waste is achieved.

Description

technical field [0001] The invention relates to a Pseudomonas fluorescens N1 and its application in the resource utilization of solid waste combined with full bionic simulation, which belongs to the technical field of biological fermentation and soil pollution restoration. Background technique [0002] Solid waste contains a lot of nutrients, but due to silicate capping and alkaline conditions, most of them cannot be directly absorbed and utilized by crops. The traditional composting fermentation process has high cost, low efficiency, and no large-scale consumption capacity. and cannot be widely used. [0003] Various nutrients in the soil form a natural circulation system, especially under certain environmental conditions, such as swamps and ocean tidal lands, there will be a large number of nutrient carbon deposits rich in plants that can absorb them, such as peat mines, peat mines, etc. . [0004] Industrial and agricultural solid waste has gradually become a problem in...
