Continuous Biosorption on Copper (II) and Industrial Wastewater Treatment by Saccharomyces Cerevisiae Biomass in Upflowing Reactor

摘要

Put dead immobilized saccharomyces cerevisiae biomass into column of continuous upflowing reactor, investigated immobilized materials on copper (II) adsorption through batch adsorption procedures, breakthrough curves of different immobilized materials, initial pH values, flow rates and diameters of immobilized products were studied on copper (II) adsorption, desorption tests and industrial wastewater treatment were analyzed. The results showed: saccharomyces cerevisiae was a perfect kind of adsorbent and feasible for removing on copper (II) with low concentration in wastewater. The immobilized materials adsorbed little on copper (II). Initial pH values, flow rates and diameters of immobilized saccharomyces cerevisiae products could affect copper (II) adsorption to some extent. The desorption tests showed that 0.1 mol ldr L-1 HCL was optimal. And immobilized saccharomyces cerevisiae biomass in continuous upflowing reactor were effective on industrial wastewater treatment.
