Abstract | This study investigated the effect of nickel on properties and microbial community of bulking activated sludge when 60-240. mg/L Ni(II) was dosed continuously in a sequencing batch reactor (SBR) over 350. days. Results showed that 120. mg/L nickel did not significantly inhibited removal of organic pollutant by activated sludge. However, the system was completely upset when 240. mg/L Ni(II) was dosed. Improvement of settling and dewatering ability was also observed with the addition of Ni(II). In addition, investigations by polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) of 16S rDNA of bacteria strain demonstrated that Ni(II) significantly affected microbial community of bulking activated sludge, judging from the elimination of original species and emergence of possible new nickel-resistant bacteria. The effect of nickel on shift of microbial community was an important cause resulted in the improvement of sludge properties in this bulking activated sludge system. © 2010 Elsevier Ltd. | ||||||||||||
