Hydrogen Sulfide Removal From Water
The method of removing hydrogen sulfide from water
Water contains hydrogen sulfide, which tastes bad and harmful. It has a way to get rid of it. All kinds of methods.
One is the precipitation method. Throw it with iron salts, iron and hydrogen sulfide meet, and iron sulfide sinks. Such as ferrous sulfate, which decomposes in water, ferrous ions combine with sulfur ions in hydrogen sulfide to form ferrous sulfide, which is insoluble in water, sinks in the bottom, and can be filtered out later.
The second is the aeration method. Expose water to gas, and hydrogen sulfide escapes. Oxygen and hydrogen sulfide in the air should be oxidized by hydrogen sulfide to form sulfur and water. Put water in an open container, or use an aeration device, and blow air into it to increase water and gas contact, and promote hydrogen sulfide dispersion.
The third is the oxidation method. Use strong oxidizing agents, such as chlorine dioxide, potassium permanganate, etc. Chlorine dioxide meets hydrogen sulfide, which quickly undergoes an oxidation reaction, and hydrogen sulfide is converted to sulfate and other harmless substances. Potassium permanganate is also highly oxidizing, which can break the structure of hydrogen sulfide, remove hydrogen sulfide from water, and achieve the purpose of purifying water quality.
All these methods have their own advantages and disadvantages. When used, according to the water conditions, cost, efficiency, etc., the appropriate method is selected to remove hydrogen sulfide from water, keep water pure, and is suitable for human use.
