Amphibious Sediment Restoration Platform for In-Situ Pollutant Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sediment treatment technologies, both in-situ and ex-situ, cause damage to the ecological environment of rivers and lakes, with ex-situ methods leading to large-scale dredging and ecological disruption, and in-situ methods failing to adequately address pollutant removal without ecological harm.
Innovation Solution
An amphibious platform equipped with a screw suction device, dehydration device, sediment treatment device, grass blanket processing device, and grass blanket paving device, which collectively suck, dehydrate, treat, and restore sediment in-situ by forming a planting base and planting submerged grass blankets to restore the ecological balance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ex-situ sediment restoration technology is used to treat polluted sediment, then the concentration of pollutants in sediment can be reduced, but large-scale dredging work is required and the original ecological environment of river sediment is destroyed
Solution Approach 1:
The patent introduces an amphibious platform as an intermediary device that enables sediment treatment directly in the water body without requiring complete dredging and land-based processing. The platform integrates dehydration, treatment, and restoration functions in one mobile unit, allowing polluted sediment to be treated in-situ while minimizing ecological disruption.
Solution Approach 2:
The system processes and treats the sediment on-site using the amphibious platform, eliminating the need to transport sediment to land-based facilities. The platform performs dehydration, pollutant removal, and restoration functions directly at the sediment location, making the system self-sufficient and avoiding ecological damage from large-scale dredging and transport.
2Object-affected harmful factors
If in-situ restoration technology is used to treat polluted sediment, then the original ecological environment can be preserved to some extent, but the treatment effectiveness is insufficient and pollutant removal is inadequate
Solution Approach 1:
The patent combines multiple treatment functions (dehydration, chemical treatment, biological treatment, and sediment stabilization) into a single integrated amphibious platform. This merging of functions ensures thorough pollutant removal while maintaining ecological balance, as all treatments occur in-situ without requiring sediment removal.
Solution Approach 2:
The system employs multiple treatment stages that progressively change the physical and chemical parameters of the sediment. Dehydration reduces moisture content, chemical treatments alter pollutant concentrations, and biological treatments transform organic contaminants, achieving effective pollutant removal while preserving the sediment matrix for ecological restoration.
3Object-affected harmful factors
If traditional dredging work is used to remove polluted sediment, then the sediment can be isolated from the water body, but a large amount of dredging work is required and subsequent sediment disposal is difficult
Solution Approach 1:
The patent extracts only the polluted portion of the sediment through targeted dehydration and treatment processes, rather than removing entire layers of sediment. The amphibious platform processes sediment in-place, extracting contaminants and excess water while leaving the treated sediment to be restored in its original location, dramatically reducing dredging volume and disposal requirements.
