The degradation performances of triphenyltin chloride （TPTCl）, dimethyl phthalate （DMP）, as well as rhodamine B （RhB） were investigated. The results indicated that removal efficiency of 50 mg/L RhB, 60 mg/L DMP and 120 mg/L TPTCI can reach 88.6%, 92.5% and 89.4% for 60 min, 50 min and 75 min, respectively. By comparison of removal efficiency, we found 206 nm is superior to 253.7 nm UV in wastewater treatment, implying it is an effective, promising, and worthwhile exploring technology to decompose organic pollutants in wastewater.展开更多
邻苯二甲酸二甲酯(DMP)作为一种在环境中广泛存在的有毒化合物,已被中国列为优先控制污染物。采用无机盐培养基从长期覆盖农膜的黑土中分离鉴定了一株能够以DMP为碳源的菌株QD-9-10,根据菌落的形态特征及16S r DNA碱基序列同源性分析,鉴...邻苯二甲酸二甲酯(DMP)作为一种在环境中广泛存在的有毒化合物,已被中国列为优先控制污染物。采用无机盐培养基从长期覆盖农膜的黑土中分离鉴定了一株能够以DMP为碳源的菌株QD-9-10,根据菌落的形态特征及16S r DNA碱基序列同源性分析,鉴定QD-9-10为Bacillus sp.。正交实验结果表明,菌株QD-9-10的最优降解条件为p H 8.0,温度35.0℃,摇床转速124.0 r·min-1,DMP初始浓度100.4 mg·L-1,在32 h时内可将DMP完全降解。底物利用能力测试表明,菌种QD-9-10具有可降解多种邻苯二甲酸酯(PAE)的能力。由此可见,Bacillus sp.QD-9-10在修复PAEs污染环境方面有一定应用前景。展开更多
