摘要: 用厌氧技术从电镀铬淤泥中分离出SRⅠ高效菌株。对SRⅠ菌净化电镀铬废水的研究表明,电镀废水中的Zn2+、UO22-和Sr2+对SRⅠ菌净化铬有促进作用,Ag+、CA2+和SiF62-对其有抑制作用,SO42-、CO32-和Cl-无影响。在铬(Ⅵ)浓度5—600μg·ml-1、pH6—7,20—30℃,SRⅠ菌对铬(Ⅵ)的净化率达99.6%。

Abstract: Ahigh efficient strain SR Ⅰ is isolated from Cr(Ⅵ) containing electroplating sludge under anaerobic culture, and its purification effect on electroplating effluent is studied. In electroplating effluent, the purification rate of Cr(Ⅵ) by strain SR Ⅰ is stimulated by Zn2+,UO22+ and Sr2+, inhibited by Ag+, Cd2+ and SiF62-, and not influenced by SO42- CO32- and Cl-. The purification efficiency of strain SR Ⅰ is 99.6% at 5-100μg Cr(Ⅵ)ml-1, pH6-7 and 20-30C.
