The invention discloses a reconfigurable modular microbial group system, a preparation method and a preparation device thereof, and the reconfigurable modular microbial group system can be used for carbon-neutral sustainable water treatment, in particular for the treatment of petroleum pollutants , which has a core-shell structure, the core part is composed of chlorella and a hydrophilic carrier for immobilizing chlorella, the shell part is composed of alkanobacterium and a lipophilic carrier for immobilizing alkanobacterium, the diameter of the core part is is 100±10 μm, and the thickness of the shell portion is 20±5 μm. The surface of the lipophilic shell can quickly absorb tiny oil droplets in water, which are degraded into carbon dioxide and minerals by the alkane-eating bacteria in the shell part. For its own life activities and oil degradation, through the above synergy and material exchange, the 7-day degradation rate of the modular microbiota system for wastewater with a crude oil pollution concentration of 10g/L was 95.8%, reaching an unprecedented degradation efficiency. |
