Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large sewage and wastewater treatment plants face challenges in managing odor-causing components, hydrogen sulfide generation, and the need for multiple chemical combinations at various points, which complicates the treatment process and increases costs due to price fluctuations and storage issues.
Innovation Solution
The use of iron-based compounds, such as ferrous chloride, ferric chloride, and magnesium hydroxide, in combination with alkaline components, to reduce odor-causing components and simplify the treatment process by controlling vapor and liquid phase hydrogen sulfide levels, thereby minimizing the need for multiple chemical combinations and optimizing chemical usage.

Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple chemical combinations are used at multiple loading points to control odor and hydrogen sulfide, then odor control effectiveness is improved, but device complexity and operational complexity increase
Solution Approach 1:
The patent combines multiple chemical functions into a single composition that contains both iron-based compounds (for hydrogen sulfide control) and alkaline components (for odor control). This merging eliminates the need for separate chemical dosing systems and multiple loading points, reducing device complexity while maintaining odor control effectiveness.
Solution Approach 2:
The single composition serves multiple functions: it controls hydrogen sulfide through iron-based compounds, controls odors through alkaline components, and provides chemical optimization. This multi-functionality replaces the need for multiple specialized chemicals and dosing systems, simplifying the overall treatment process.
2Object-affected harmful factors
If multiple chemicals are stored and transported to different locations for treatment, then treatment effectiveness is improved, but ease of operation deteriorates
Solution Approach 1:
By combining iron-based compounds and alkaline components into a single composition, the patent eliminates the need to transport and store multiple separate chemicals. The single composition can be dosed at one location, significantly improving ease of operation while maintaining hydrogen sulfide control effectiveness.
3Object-affected harmful factors
If chemical dosing is increased to address changing wastewater conditions and odor generation, then odor control effectiveness is improved, but loss of substance and cost increase
Solution Approach 1:
The patent optimizes the chemical composition by adjusting the ratios and concentrations of iron-based compounds and alkaline components. This parameter optimization ensures effective odor and hydrogen sulfide control while minimizing the total quantity of chemicals required, reducing both chemical loss and operational costs.
