El sistema de recuperación de solventes utiliza el principio de destilación, calentando el solvente de evaporación en un vapor gaseoso, el vapor en el flujo de salida de licuefacción del sistema de enfriamiento, de modo que la recuperación de solvente orgánico limpio. residuos, sucios, viejos solventes orgánicos regeneración, reciclaje y reutilización.
Descripción general de Aguas residuales de la industria del mecanizado
Aguas residuales de la industria del mecanizado
Treating wastewater from the machining industry’s metal surface spraying and cleaning processes presents several challenges:
High Concentrations of Contaminants: The wastewater often contains oils, solvents, heavy metals, and fine particulates, which are difficult to separate and treat effectively.
Complex Chemical Composition: The varied chemicals used in metal cleaning and surface treatment can lead to complex wastewater composition, requiring multi-step treatment processes.
Emulsified Oils: Oils in the wastewater are often emulsified, making traditional separation techniques less effective and requiring specialized treatments like chemical demulsification.
Heavy Metal Removal: Removing heavy metals such as lead, chromium, and nickel is challenging due to their tendency to form stable complexes in water.
Cumplimiento normativo: Meeting stringent environmental regulations for discharge, especially for heavy metals and toxic substances, adds complexity to the treatment process.
High Treatment Costs: The need for advanced treatment technologies and frequent maintenance drives up the cost of wastewater treatment in this sector.
