Treatment of Stainless Steel Pickling Wastewater by Ion Resin Exchange and Activated Carbon Adsorption
Abstract:
The static adsorption of stainless steel pickling wastewater by ion resin exchange and activated carbon adsorption was studied respectively. The results shown that, the static saturate adsorption capacity of 001×7 dry resin for Cr3+and Fe3+ in the wastewater was 60.34mg/g and 65.3mg/g respectively, and the elution rate of saturated resin by using Na2SO4 and H2SO4 can reach 99%. The saturate adsorption capacity of activated carbon for Cr3+and Fe3+ in the wastewater was 4.55 mg/g and 40.76 mg/g respectively, and NaOH as desorption reagent had a good desorption effect to activated carbon. The regeneration of activated carbon was also carried out.
