The wastewater discharged from the production of titanium dioxide by the sulfuric acid method is mainly acidic wastewater, which mainly contains free sulfuric acid, ferrous sulfate metatitanic acid and other metal ion sulfates. At present, lime neutralization is mainly used to treat this wastewater papermaking white mud, which is a large amount of caustic waste residue produced in the alkali recovery process of pulp and paper mills. It has not been properly dealt with, causing environmental pollution and requiring huge sewage discharge costs.
In order to comprehensively utilize resources and achieve the effect of treating waste with waste, Xi'an Environmental Technology Company has developed equipment for producing crude iron yellow products from titanium dioxide wastewater. This equipment uses ferrous sulfate, which is filtered, dried and crushed to finally turn into iron yellow that can bring economic benefits to the enterprise. It not only solves the environmental protection problem, but also brings certain economic benefits to the enterprise. It can be said that this is a new idea for titanium dioxide wastewater treatment. This equipment has won unanimous praise from the majority of users due to its strong ability to process waste acid, low processing cost, high degree of automation, long service life and our perfect after-sales service!
