   In the chemical production process of biopharmaceuticals, organophosphorus pesticides, petrochemical refining, heavy metal smelting and other chemical production processes will produce a large number of high-salt wastewater, which often contain a variety of toxic substances and ultra-high pH, for such high COD, high-salt wastewater, effective measures must be taken to deal with. Otherwise, it will cause serious environmental pollution. Therefore, for all kinds of high salt wastewater produced in chemical production, it is necessary to classify and select the optimal process according to the different sources and properties of high salt wastewater. Our company for such high COD, high salt wastewater treatment to achieve technological breakthroughs, high salt wastewater drying experiments with drum scraper dryer, successfully tested a variety of miscellaneous salt wastewater, to solve the process of high salt wastewater disposal in the field of pain points.

  In order to overcome the shortcomings of the existing technology, our company provides a solid waste salt chemical wastewater reduction drying treatment method, the method of new materials, chemical, petrochemical, chemical water, recycled water and other systems of high salt wastewater through the MVR continuous concentration and evaporation of salt concentration produced through the drum dryer direct evaporation treatment. The method contains sodium sulfate and sodium chloride and other mixtures of chemical impurity salt wastewater as raw materials, the use of drum dryer evaporation and drying off impurity salt solidification, evaporation of water and gas in the water shower tower dust removal and discharge. Both combined with the characteristics of solid waste heterosalt resources, but also make full use of chemical resources, reducing the disposal of heterosalt wastewater link, the large mass of wastewater reduction and drying, compared with the traditional high salt wastewater treatment system, the treatment volume can be reduced by 50% to 70%, the equipment energy consumption can be reduced by 50% to 80%, and the energy costs reduced by 30% to 60%.

   Through the high salt wastewater reduction drying technology, saving the enterprise wastewater disposal costs, not only make full use of chemical resources, but also to achieve the true meaning of the chemical plant wastewater treatment system “zero discharge”.
