中文摘要：

研究了复合生物吸附剂FY01和活性污泥处理含铬电镀废水的吸附性能。结果表明，铬的生物吸附分为快速吸附和缓慢吸附两个阶段。FY01具有良好的吸附稳定性，对废水的pH适应能力强，当pH=2．5-6时，10g·L^-1 FY01和5g·L^-1污泥曝气处理2000mL电镀废水2h后，68．6mg·L^-1含铬通用电镀废水中总铬的去除率达71．5～75．6％；50．1mg·L^-1含铬康力电镀废水中总铬的去除率高达80．0—90．0％。FY01和活性污泥具有良好的协同促进作用，10g·L^-1 FY01和15g·L^-1污泥对通用电镀废水、康力电镀废水中铬的联合去除率分别高达97.7％和88．1％，比两者单独处理电镀废水的除铬率总和分别高出39.8％、44．6％。

英文摘要：

The capability of bioadsorption of chromium-galvanized wastewater by biosorbent FY01 and activated sludge was discussed in this paper. The experimental results showed that process of chromium biosorption were comprised with fast and slow adsorptions. The pH adaption ability of FY01 to wastewater was effective because of its stability of biosorption. After the aerobic treatments to Tongyong chromium-galvanized wastewater which concentration of total Cr was 68.6 mg·L^-1 and Kangli galvanized wastewater which concentration of total Cr was 50.1 mg·L^-1 for two hours, the total Cr removal ratios on 10 g·L^-1 FY01 and 5 g·L^-1 activated sludge were 71.5-75.6% and 80.0-90.0%, when pH was 2.5-6.0. FY01 and activated sludge has a better cooperation-promotion action. The cooperation removal ratios of Tongyong and Kangli chromium-galvanized wastewater on 10 g·L^-1 FY01 and 15 g·L^-1 activated sludge were 97.7 % and 88.1% respectively, 39.8% and 44.6% better than the treatments separately.
