Solution Overview
Problem
The existing photooxidative treatment apparatus may discharge poorly purified water due to unstable concentrations of photocatalyst particles during operation, affecting treatment efficiency and leading to suboptimal purification outcomes.
Innovation Solution
A liquid treatment method and apparatus that includes a first tank with photocatalyst particles, a light source for UV irradiation, a filtration membrane, and a channel switch to control the circulation and discharge of treated liquid, ensuring photocatalyst particle concentrations remain within optimal ranges for efficient treatment by switching between circulation and discharge states based on detected concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the liquid treatment apparatus operates continuously with fixed discharge settings, then the operational simplicity is maintained, but the treatment quality deteriorates due to unstable photocatalyst particle concentrations
Solution Approach 1:
The system dynamically adjusts the channel switch between circulation and discharge states based on real-time photocatalyst particle concentration monitoring. This dynamic control ensures that liquid is only discharged when treatment quality meets standards, resolving the contradiction between operational simplicity and treatment reliability
Solution Approach 2:
The concentration monitoring device provides continuous feedback on photocatalyst particle levels, which automatically triggers the channel switch to adjust between circulation and discharge modes. This feedback mechanism maintains treatment quality without requiring manual intervention, preserving operational simplicity
2Reliability
If the channel switch frequently alternates between circulation and discharge states, then the treatment quality is maintained, but the system complexity increases
Solution Approach 1:
The system uses automated concentration monitoring and control logic to self-regulate the channel switch between circulation and discharge states. This self-service approach maintains treatment quality without requiring complex external control systems or manual operation
Solution Approach 2:
The channel switch serves multiple functions: it automatically alternates between circulation and discharge modes based on concentration thresholds, and also responds to tank liquid level conditions. This multi-functionality maintains treatment quality while avoiding the need for separate dedicated control mechanisms
3Adaptability or versatility
If the photocatalyst particle concentration is allowed to vary freely, then the operational flexibility is maintained, but the treatment efficiency deteriorates
Solution Approach 1:
The system maintains treatment efficiency by controlling photocatalyst particle concentration within optimal thresholds. When concentration exceeds upper or lower limits, the channel switch redirects flow to circulation mode, preventing efficiency degradation while allowing flexible operation within the optimal parameter range
Solution Approach 2:
The system performs preliminary concentration monitoring and prediction to anticipate when photocatalyst levels will exit the optimal range. This allows proactive adjustment of the channel switch to maintain efficiency before treatment quality actually deteriorates

Data Source
AI summary
The present disclosure provides a liquid treatment method and apparatus according to which poorly treated liquid is prevented from being discharged to the outside thereof. The liquid treatment apparatus of the present disclosure comprises a channel switch, a return channel that establishes communication between the channel switch and an internal space of a first tank, and a discharge channel that establishes communication between the channel switch and the outside of the liquid treatment apparatus. In the circulation state, the liquid mixture is circulated in the liquid treatment apparatus so as to return a liquid to the first tank through the return channel. If a concentration of the photocatalyst particles contained in the first tank falls within a predetermined range, the channel switch is switched from the circulation state to the discharge state to discharge the liquid to the outside of the liquid treatment apparatus.
