Coal is one of the main energy sources.
Plays a crucial role in connecting the past and the future in life! But the mining of coal can also bring harm to our living environment and pose a threat to ecological issues!
Coal mining:
Mine water is a polluting industrial wastewater discharged during the coal production process The discharge of mine water is large, and direct discharge seriously wastes water resources and brings great pressure to the environment! Managing and managing mine water well not only preserves valuable water resources, but also alleviates water supply pressure in various regions and promotes the sustainable and healthy development of coal mines in different areas!
Facing problems:
Coal mine water treatment, with turbid effluent and large drainage volume?
Is there a lot of suspended solids in mine water that cannot be treated thoroughly, and the sedimentation of suspended solids in the inclined pipe sedimentation tank is not thorough?
The treatment scale of coal mine water is 100m3/h. For such a large amount of wastewater to be treated and clarified quickly, polyacrylamide primary polyaluminum chloride flocculant is needed! The key to mine water treatment lies in the selection of chemical technology! For polymers in mine water treatment, the larger the charge carried by the chain like molecules, the higher the charge density, and the more fully the chains can stretch. The range of adsorption bridging is also larger, and the coagulation effect will be better.
Polyacrylamide can be used as a flocculant for water purification. In coagulants, substances that can cause sedimentation of sediment, suspended particles, and other substances in water are called coagulants. According to their chemical composition, coagulants can be divided into inorganic coagulants and organic coagulants. Inorganic coagulants are more commonly used in aluminum salt and iron salt systems, such as aluminum sulfate, ferric chloride, aluminum chloride, polyaluminum chloride, etc. (PAC); Organic polymer flocculants include polyacrylamide (PAM), sodium polyacrylate (ASAP), etc.
In coagulants, substances that can cause sedimentation of sediment in water are called coagulants. The commonly used coagulants mainly include inorganic cationic polymers such as hydroxyaluminum and hydroxyzirconium. These inorganic cationic polymers can dissociate in water, giving multi nucleated hydroxyl bridging ions and neutralizing the negative charge on the surface of solid suspensions.
The technical team of Yuxinhuan tailored a flocculant dosing plan based on the actual situation of the coal mine plant, and tracked the treatment effect throughout the process to ensure the smooth implementation and stable operation of the project. In the future, Yuxinhuan will continue to be committed to the development of environmental protection and provide efficient and reliable sewage treatment solutions for more customers.
