Technical Transformation of Tripe Effect Evaporation Device in a Hazardous Waste Disposal Enterprises
In recent years,with the increasing improvement of environmental protection regulations,various enterprises have more and more perfect environmental protection facilities,and the wastewater they outsourced presents the characteristics of high salt and high organic content.Third-party hazardous waste treatment enterprises need to improve need to improve their technology to overcome the difficulties such as the small number,various types and complex composition of wastewater business.The composition of high-salt wastewater is complex,physicochemical treatment methods such as the membrane concentration,flocculation sedimentation and pressure filtration can only remove some precipitable inorganic salts and a small amount of organic wastes,it can not be thoroughly treated.Evaporation is a common process for high salt wastewater treatment in hazardous waste disposal enterprises,this article describes in detail the technical transformation of the triple-effect evaporation system in a hazardous waste enterprise.Compared with MVR evaporation,triple effect evaporation has more advantages in treating high boiling point wastewater.
