The invention relates to a method for using
signal molecules for accelerating repair of disintegrated aerobic granular
sludge. According to the method for using the
signal molecules for accelerating repair of the disintegrated aerobic granular
sludge, by adding the exogenous AHLs
signal molecules to repair the disintegrated the aerobic granular
sludge, in a process of repairing structures of the disintegrated aerobic granular sludge, regranulation of the crushed granular sludge is accelerated, after 20-30 days, the disintegrated aerobic granular sludge is basically and completely repaired, therepaired aerobic granular sludge is smooth in particle surface, regular in shape and compact in structure, and has good
settling performance, after adding of the exogenous AHLs is stopped, the granular sludge structures are still intact, and the
settling performance and the granule density remain at high levels. According to the method for using the signal molecules for accelerating repair of thedisintegrated aerobic granular sludge, by adding the exogenous AHLs temporarily, an excellent repairing effect on the disintegrated aerobic granular sludge is achieved, the repaired granular sludge is intact in structure and good in
settling performance, moreover, operation is simple, and practical application is easy.
