Iron Hydrogen Sulfide Removal
The method of removing iron and hydrogen sulfide
In ancient times, those who want to purify water well are often trapped in the disturbance of iron and hydrogen sulfide. Iron exists in water, which makes the water color change, the taste is not good, and it is easy to rust the utensils; the gas of hydrogen sulfide smells bad and is harmful to human health. Therefore, the removal of iron and hydrogen sulfide is an important task in water management.
If you want to remove iron, you should know the state of iron in water. If it is ferrous ions, you can use the method of oxygen exposure. Expose water to the air, ferrous ions get oxygen, turn into trivalent iron ions, and then hydrolyze into iron hydroxide precipitation, and then remove it by precipitation and filtration. Or use manganese sand filter material, which can catalyze the oxidation of ferrous ions in water, speed its precipitation, and achieve the effect of removing iron.
As for hydrogen sulfide, chemical methods can be used. Add an appropriate amount of strong oxidants, such as hydrogen peroxide, potassium permanganate, etc. When hydrogen sulfide encounters it, an oxidation reaction occurs, and it is converted into sulfur elemental substance or sulfate ion, and the odor is self-removing. It can also be adsorbed with activated carbon. The surface of activated carbon is porous, and hydrogen sulfide molecules can be attached to it, so that the odor of water can be solved.
There are biological methods to remove hydrogen sulfide. In a specific environment, cultivate microorganisms that can oxidize hydrogen sulfide. Such microorganisms feed on hydrogen sulfide and convert it into harmless substances. This method is mild and has little impact on water quality.
Those who govern water understand the method of removing iron and hydrogen sulfide, and choose the appropriate method according to the feeling of water, so that the water can be clean and beneficial to people's livelihood.
