主　　题：nanobubble water remediation nanobubble generation dissolved oxygen hydraulic air compression 

摘      要：The anoxia of coastal water has already been a serious problem all over the *** are proved to have great applications in water remediation because they could effectively increase the oxygen content and degrade organic matters in *** the existing methods to produce nanobubbles are complicated and high cost to operate,especially in deep *** this paper,we presented a low-cost method,hydraulic air compression(HAC),to produce a large number of nanobubbles and proved that nanoscale gas bubbles could be produced by HAC for the first *** tracking analysis was used to measure the size and concentration of produced *** indicated that the concentration of nanobubbles would increase as the downpipe height *** measurements proved that produced“nanoparticlesare gas nanobubbles *** dissolved oxygen in water would provide the source for larger number of nanobubble *** results are expected to be very helpful for water remediation in ocean in the future.
