Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a method to reduce the volume of excess sludge with minimal environmental impact, as current incineration treatments generate greenhouse gases.
Innovation Solution
Development of bacteria capable of degrading microorganisms present in excess sludge, specifically utilizing a bacterium with a 16S rRNA gene sequence having 98.2% or more identity to SEQ ID NO: 1, and a microbial preparation containing these bacteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If incineration treatment is used for excess sludge, then volume reduction is achieved, but greenhouse gas emissions increase
Solution Approach 1:
The patent replaces the thermal/mechanical incineration system with a biological degradation system using specifically cultured bacteria. Instead of burning sludge at high temperatures to reduce volume, the invention uses microbial action to naturally decompose and reduce sludge volume, thereby eliminating greenhouse gas emissions while achieving the same volume reduction goal
Solution Approach 2:
The patent changes the fundamental parameter of the treatment process from thermal energy input (incineration) to biological activity (bacterial degradation). By culturing specific bacteria under controlled conditions and applying them to excess sludge, the system achieves volume reduction through biochemical processes rather than combustion, thus resolving the contradiction between volume reduction and environmental harm
2Volume of moving object
If conventional sludge treatment methods are used, then volume reduction is achieved, but environmental impact increases
Solution Approach 1:
The patent employs bacteria that naturally possess the capability to degrade organic matter in excess sludge. By culturing and multiplying these bacteria under controlled conditions, the system creates a self-propagating degradation process where the bacteria reproduce and continue to reduce sludge volume without requiring external energy input or chemical additives, thereby minimizing environmental impact while achieving volume reduction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bacteria effectively degrade target microorganisms, reducing the volume of excess sludge while minimizing environmental impact by avoiding greenhouse gas emissions.
