Sewage treatment agents are chemicals used to treat pollutants, organic matter and microorganisms in sewage. According to its function and mechanism, sewage treatment agents can be divided into the following:
Oxidant: Oxidant can promote the oxidation reaction of organic matter and convert organic matter into harmless products. Common oxidants include potassium permanganate, sodium sulfate and chlorine.
Agents: The condenser can gather suspended particles and colloidal substances into large blocks, which is convenient for precipitation or filtering separation. Common coagulants include polymer aluminum chloride (PAC), polyacrylamide (PAM), etc.
Devinizer: Devinic agent can eliminate the smell of odor in sewage and improve environmental air quality. Common deodorants are sodium chloride and sodium chloride.
Bybaches: bactericides can effectively kill or inhibit microorganisms in sewage to prevent the spread of pathogenic bacteria and bacterial reproduction. Common bactericides include sodium chloride, chlorine dioxide and ultraviolet disinfection.
Chelators: Chelators can form complexing with metal ions, thereby reducing the impact of metal ions on sewage and promoting its precipitation or removal. Common chelated agents include ethyleine tetraitine (EDTA) and phosphoric acid.
Tonalide: Trumite can be used to remove colors in sewage and improve the transparency and aesthetics of water. Common luminous agents include activated carbon and hydrogen peroxide.
These sewage treatment agents are usually combined according to the actual situation and needs to achieve efficient, economic and environmentally friendly sewage treatment effects. When use, we should follow relevant operating procedures and ensure the safety storage and treatment of the agent to ensure the safety and environmental protection of personnel.
