✅ Denitrification MICP Mechanism Diagram [Standard Drawing Instructions (Final Usable Version)]
Purpose:
Suitable for the schematic diagram of denitrification-induced microbial calcium carbonate precipitation (Denitrification-induced MICP). The reaction path strictly corresponds to the stoichiometric relationship, and urea-based MICP is not mixed.
I. Figure title
Schematic diagram of the mechanism of denitrification-induced microbial calcium carbonate precipitation
Mechanism of denitrification-induced microbial calcium carbonate precipitation
II. Overall layout (strongly recommended)
Horizontal or vertical flow chart
Upstream → Downstream
Chemical reactions are mainly at the solution scale
Bacteria only serve as reaction drivers and nucleation interfaces
III. Structures and elements in the figure (detailed description)
(1) Denitrification reaction zone (core reaction)
Location: Left or top of the figure
Labeling content (use as is):
5CH₃COO⁻ + 8NO₃⁻ + 13H⁺ → Denitrifying bacteria → 10CO₂↑ + 4N₂↑ + 14H₂O
Drawing requirements:
CH₃COO⁻ and NO₃⁻ point to denitrifying bacteria with arrows
N₂ and CO₂ are indicated by "↑" to indicate gas escape
Do not draw intermediate valence states (NO₂⁻, NO, N₂O, etc.)
(2) Denitrifying bacteria (only as a functional carrier)
Morphological requirements (very important):
Elliptical or short rod-shaped
No flagella
Smooth surface
Do not draw complex intracellular metabolic pathways
Label:
Denitrifying bacteria
Denitrifying bacteria
Function description (can be labeled in small print):
Provide a denitrification environment and nucleation interface
(3) Inorganic carbon conversion process (carried out in solution)
Location: Below or to the right of the denitrification zone
Reaction formula labeling:
CO₂ + H₂O ⇌ HCO₃⁻ + H⁺
Drawing requirements:
CO₂ flows out from the denitrification reaction arrow
HCO₃⁻ is clearly labeled as formed in the solution
Do not put it inside the cell
(4) Calcium carbonate precipitation zone (final result)
Location: Bottom or far right of the figure
Reaction formula labeling:
Ca²⁺ + HCO₃⁻ + OH⁻ → CaCO₃↓ + H₂O](/_next/image?url=https%3A%2F%2Fpub-8c0ddfa5c0454d40822bc9944fe6f303.r2.dev%2Fai-drawings%2FAhBWBfY39jdWmvaOGBDP2gfuJD6qWUOH%2F09ab8c96-ecab-4ce0-bcee-ad7566c0c10f%2Fc59b94cb-b5bb-4b22-87e4-ea94a82b8aa0.png&w=3840&q=75)
