Abstract:
The treatment of industrial wastewater containing naphthalene by using magnesium sulfate has been studied.The effects of pH value and magnesium sulfate dosage on decolorization efficiency are investigated.The resultsshow that the magnesium sulfate is a safe,nontoxic,harmless,environmental friendly water treatment agent,It hasan excellent capacity to remove naphthalene substances from wastewater.When the magnesium sulfate dosage is 195g/L,and pH 11.5,the decolorization rate reaches 95% and the removal rate of COD is more than 80%.
