Technical Field

[0001] The invention relates to the technical field of groundwater treatment, in particular to desulfurization equipment for sulfur-containing hot spring water. Background Art

[0002] Hot springs are a type of spring water that naturally gushes out from underground. These springs, with temperatures significantly higher than the local average annual temperature, contain minerals that are beneficial to human health. Hot springs can relax muscles and blood vessels, accelerate blood circulation and metabolism, and soften cuticles. Sulfur can reduce inflammation and kill bacteria, making it effective for common infectious and parasitic skin diseases.

[0003] Hot spring water contains sulfur, manganese, iron, and other impurities, significantly exceeding sanitary standards for drinking water and industrial water. Hydrogen sulfide is an acutely toxic substance; inhaling even a small amount of high-concentration hydrogen sulfide can be fatal within a short period of time.
