Innovation Solution
A bionic device mimicking the human digestion system, comprising a pre-treatment unit, biomimetic intestine tubular purification system, microbial fuel cell, and inclined tube sedimentation tank, which uses enzymes, microorganisms, and solar power to degrade organic materials and convert chemical energy into electrical energy for oxygenation, thereby improving water quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If normal aeration device is used, then aeration oxygenation is provided to improve redox state, but oxygen dissolution is low and energy consumption is high
Solution Approach 1:
The aeration system is segmented into multiple micro-aeration devices distributed throughout the water body, each providing localized oxygenation. This segmentation increases the total surface area for oxygen transfer while reducing the energy required per unit volume of water treated, resolving the contradiction between low oxygen dissolution and high energy consumption.
Solution Approach 2:
The invention transitions from traditional bulk aeration to micro-scale aeration by introducing numerous small air bubbles through micro-pores. This dimensional change from macro to micro scale dramatically increases the oxygen dissolution efficiency while reducing the energy input required, directly addressing the technical contradiction.
2Reliability
If conventional aeration technology is used, then oxygenation is provided, but degradation of organic materials and ammonia nitrogen is insufficient
Solution Approach 1:
The invention introduces bottom sludge purification agents as intermediaries that contain specialized microorganisms. These agents mediate between the aeration system and the organic pollutants, enhancing the degradation of organic materials and ammonia nitrogen while improving overall water quality. The purification agents act as catalysts that accelerate the decomposition process.
Solution Approach 2:
The invention changes the chemical and biological parameters of the water body by introducing purification agents that alter the microbial community structure. This parameter change enables more effective degradation of organic materials and ammonia nitrogen, transforming the water quality from poor to compliant with Grade IV standards.
3Productivity
If bottom sludge purification agent is added, then degradation ability is improved, but operation complexity increases
Solution Approach 1:
The bottom sludge purification agents are designed to self-propagate and self-maintain within the water body. Once introduced, the microorganisms in the purification agents reproduce and sustain themselves, continuously degrading organic materials without requiring frequent manual intervention. This self-service characteristic maintains high degradation ability while keeping operations simple.
