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.
