Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous extraction and purification of tail water from specific areas is performed, then purification treatment is achieved, but comprehensive treatment based on actual tail water distribution cannot be guaranteed
Solution Approach 1:
The system performs preliminary detection of tail water distribution in the pond before extraction. The detection module identifies the spatial distribution characteristics of tail water, and based on this information, the system pre-adjusts the extraction locations and rates to ensure comprehensive coverage of all tail water areas, preventing any tail water from being left untreated.
Solution Approach 2:
The system implements closed-loop feedback control where the detection module continuously monitors tail water distribution in the pond, and the control module adjusts extraction parameters based on this real-time feedback. This ensures that extraction operations dynamically adapt to actual tail water distribution, guaranteeing comprehensive treatment while maintaining water quality stability.
2Measurement precision
If non-contact scanning detection is performed on sedimentation tank, then detection precision is improved, but device complexity increases
Solution Approach 1:
The system replaces complex mechanical contact detection methods with non-contact optical scanning detection. The detection module uses optical fields to scan the sedimentation tank and obtain sediment distribution information without physical contact, achieving high measurement precision while avoiding the complexity of mechanical sensors and their installation/maintenance requirements.
3Productivity
If environmental conditions are adjusted to maximize biological decomposition reaction, then decomposition efficiency is improved, but energy consumption increases
Solution Approach 1:
The system dynamically adjusts environmental conditions in the decomposition tank based on real-time monitoring of decomposition progress. The control module modifies parameters such as aeration rate, temperature, and pH level adaptively to maximize decomposition efficiency at each stage, avoiding excessive energy consumption by only applying necessary adjustments when and where needed.
Solution Approach 2:
The system changes physical and chemical parameters of the decomposition environment (such as dissolved oxygen concentration, temperature, pH) to optimize biological decomposition reactions. By carefully controlling these parameters within optimal ranges, the system achieves high decomposition efficiency without excessive energy input, balancing productivity and energy consumption.

AI summary
Provided is a tail water treatment and recycling system for aquaculture configured to identify the overall water body inside the aquaculture pond to determine the distribution status information of tail water within the pond. It also performs non-contact scanning detection on the water body inside the sedimentation tank, analyzes the sedimentation movement data of sediments within the tank, and evaluates this data to ensure maximum sediment settlement. Furthermore, it determines the reaction progress information inside the decomposition tank, and subsequently adjusts the environmental conditions for decomposition reactions within the tank, effectively reducing the nutrient concentration in the tail water. According to the oxygen content of the water body in the pond, it also adjusts the oxygenation operation for the tail water that has undergone decomposition, ensuring that the pond can continuously and stably receive a supply of clean, high-oxygen recycled water.
