Hydrogen Cyanide Origin in Sewage
Exploration of the source of hydrogen cyanide in sewage
In today's world, sewage treatment is related to people's livelihood and the safety of the environment. The origin of hydrogen cyanide is worth investigating in detail.
In sewage, hydrogen cyanide is born, one of which is from industrial waste. In the chemical industry, in the production process, cyanide-containing raw materials are often involved. If not properly treated, cyanide flows into sewage. After interacting with various substances in water, hydrogen cyanide is easily generated under suitable conditions, such as specific pH and temperature. For example, in the electroplating industry, the water for cleaning plating parts contains cyanide. If it is not properly treated and purified, the cyanide is gradually converted, and hydrogen cyanide is produced.
Furthermore, the decomposition of organic matter is also its source. Sewage contains many organic components, which decompose under the action of microorganisms. If the organic matter has a specific nitrogen-containing and carbon-containing structure, and the environment is hypoxic and reduced, hydrogen cyanide can be produced when microorganisms metabolize. For example, some nitrile-containing organisms, when decomposed, the nitrile group undergoes a series of biochemical reactions, or becomes hydrogen cyanide.
In addition, the influence of agricultural activities. Some pesticides and fertilizers contain cyanide components. During agricultural operations, excessive application of drugs, or rainwater initializing, cyanide-containing substances flow into the sewage with runoff. Chemical changes in the water body can also generate hydrogen cyanide. Only by understanding the source of hydrogen cyanide in wastewater can we take targeted measures to find an effective way for wastewater treatment, ensuring the cleanliness of the environment and the well-being of the people.
