Reclaimed Waterway Regulation for Algae Risk and Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to address algae risk control in reclaimed water utilization for landscape environment water allocation, neglecting seasonal river water quantity and quality variations, leading to river water quality degradation and abnormal algae reproduction.
Innovation Solution
A water distribution regulation method using nitrogen-phosphorus ratio and water replacement rate as control indicators, coupled with a joint regulation model for water-quantity and water-quality, optimized through a joint regulation model for reclaimed water in rivers, incorporating reclaimed water and surface water, to control algae growth and maintain river flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If reclaimed water is used for landscape environment water allocation, then the pressure on river and lake ecological environments is alleviated and seasonal water insufficiency is solved, but river water quality degradation and abnormal algae reproduction occur
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the nitrogen-phosphorus ratio and water replacement rate based on seasonal variations and algae risk levels. The system modifies these parameters in real-time to prevent algae blooms while maintaining adequate water quantity for landscape environments, thus resolving the contradiction between water quantity sufficiency and water quality protection.
Solution Approach 2:
The patent implements feedback mechanisms through monitoring systems that track water quality parameters, algae growth indicators, and hydrological conditions. This feedback information is used to continuously adjust the reclaimed water allocation strategy, enabling dynamic control that prevents water quality degradation and abnormal algae reproduction while maintaining adequate water supply.
2Ease of operation
If reclaimed water is diverted and allocated without considering seasonal river water quantity and quality variations, then water allocation is simplified, but river water quality degradation and abnormal algae reproduction occur
Solution Approach 1:
The patent applies dynamics by transitioning from static water allocation rules to dynamic adjustment mechanisms that respond to seasonal river water quantity and quality variations. The system automatically adapts the nitrogen-phosphorus ratio and water replacement rate based on real-time hydrological and water quality conditions, making the operation both effective and responsive to environmental changes.
3Object-generated harmful factors
If nitrogen-phosphorus ratio and water replacement rate are controlled, then algae growth is regulated, but water distribution complexity increases
Solution Approach 1:
The patent manages complexity by focusing regulation on two key parameters (nitrogen-phosphorus ratio and water replacement rate) rather than controlling all water quality variables. This parameter reduction approach simplifies the regulation system while effectively controlling algae growth, as these two parameters are the main drivers of algae reproduction in the context of reclaimed water usage.
