Research on The Treatment Technology of Wastewater Containing Polyvinyl Alcoho
The full name of polarizing film is polarizing film,which is the imaging core of liquid crystal displays.During the production of polarizing film,some wastewater is generated,including wastewater containing polyvinyl alcohol and potassium iodide.Polyvinyl alcohol(PVA)is an organic compound with a chemical formula of[C2H4O]n.Wastewater containing PVA has ahigh concentration of organic compounds and poor biodegradability,it is difficult to achieve immediate results in the treatment of PVA containing wastewater using conventional treatment processes.This article elucidates the mechanism of oxidation reaction through the theory of organic chemical covalent bonds.At the same time,through the experiment of Fenton reagent treatment of PVA wastewater,theoretical data is provided for the value of reaction parameters of Fenton oxidation method in practical engineering design.
