Existing agricultural systems face challenges in providing plants with a stable and immediate supply of plant-available nitrogen, particularly in hydroponic cultivation, and the production of chemical fertilizers contributes to carbon dioxide emissions and environmental pollution.
Innovation Solution
A bioreactor system that uses hydrogen peroxide and a catalyst to convert organic waste into an organic nutrient solution with high plant-available nitrogen content, while simultaneously absorbing carbon dioxide, utilizing a biofilm process with ammonifying and nitrifying bacteria to stabilize nitrogen and incorporate it into the solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If organic fertilizer material is used, then environmental sustainability is improved, but the fraction of plant-available nitrogen is insufficient
Solution Approach 1:
The invention changes the chemical parameters of organic nitrogen through controlled oxidation processes. Hydrogen peroxide and other oxidizing agents convert organic nitrogen compounds into forms with higher plant availability (ammonium and nitrate), achieving at least 10% plant-available nitrogen fraction while maintaining organic certification standards.
Solution Approach 2:
The invention introduces intermediary substances (hydrogen peroxide, catalysts, and other oxidizing agents) that facilitate the conversion of organic nitrogen to plant-available forms. These intermediaries enable the transformation process without requiring mineral fertilizers, thus maintaining environmental sustainability while improving nitrogen availability.
2Quantity of substance
If mineral fertilizer is used, then plant-available nitrogen is improved, but carbon dioxide emissions increase
Solution Approach 1:
The invention converts harmful organic waste materials into beneficial plant-available nitrogen through oxidation processes. This approach transforms potential environmental pollutants into valuable nutrients, eliminating the need for energy-intensive mineral fertilizer production and associated CO2 emissions.
Solution Approach 2:
The system enables organic matter to self-transform into plant-available nutrients through controlled oxidation. The organic fertilizer material serves its own purpose of providing nitrogen to plants, eliminating the need for external mineral fertilizer inputs and their associated carbon footprint.
3Object-affected harmful factors
If biological nitrogen conversion is used, then environmental impact is reduced, but nitrogen release is uncontrolled
Solution Approach 1:
The invention implements feedback control through monitoring and adjusting oxidation parameters (hydrogen peroxide dosage, catalyst concentration, reaction time, temperature). This enables precise control over the rate and extent of nitrogen conversion, ensuring stable and predictable nitrogen release patterns that meet plant requirements.
Solution Approach 2:
The system transitions from static, uncontrolled biological processes to dynamic, controllable oxidation reactions. By adjusting operational parameters in real-time, the invention achieves controlled nitrogen mineralization rates that can be adapted to different crop needs and environmental conditions.
