| Summary: | 碩士 === 朝陽科技大學 === 環境工程與管理系碩士班 === 98 === A new modeling concept is used for evaluate the effect of trivalent chromium and hexavalent chromium on the heterotrophic organisms (XH) biomass. The oxygen uptake rate (OUR) was employed to measure the constants. The result has shown that, based on the hetertroph kinetics parameters, the concentration of the heavy metals wastewater with trivalent chromium are 5、10、15、20 mg L-1 of XH, which inhibition rate are 27.87%、34.83%、42.33%、42.88%；The concentration of the heavy metals wastewater with hexavalent chromium are 5、10、15、20 mg L-1 of XH, which inhibition rate are 39.36%、42.52%、47.25%、52.02%，the value of μH is decreased with the increasing concentration of heavy metals wastewater. For the concentration of trivalent chromium heavy metals, the inhibition rate of bH are 23.08%、33.33%、61.54%、82.05%；For the concentration of hexavalent chromium heavy metals, the inhibition rate of bH are33.33%、56.41%、76.92%、110.26%.
