摘要：For the appropriate regulation of natural environment, microbiological treatment of some disinfectants with activated sludge was investigated, especially the degradation and acclimatization of some disinfectants against the activated sludge were examined. Bubbling rate of above 200 ml/min is required for the maintenance of good degradation condition in the treatment system with activated sludge. Glutaraldehyde (GA) was degraded nearly perfect, benzalkonium chloride was more degraded, 8-hydroxyquinoline sulfate was degraded moderately and chlorhexidine digluconate was slightly degraded in the activated sludge. Acclimatization of GA was worse than the other disinfectants. Three kinds of Ps. aeruginosa isolated from the acclimatization treatment system are responsible for the good treatment ability of some disinfectants.
