碩士 / 國立中興大學 / 農業機械工程學系 / 84 / In this research,the modeled tanks including square and circular
shapeswere used to simulate the properties of water and water
flows of the real culture ponds.The influences on the settlement
of solid segment, temperature distribution,
concentration of dissloved oxygen and pH levelas changes of the
numbers,revolutions and depths of the paddle wheels,were
studied.We first investigate the relation between the
disslovedoxygen and paddle wheel with several depths in water.As
the result ofthe experiment,the best consequence of maximum
dissloved oxygen is 180rpm,4cm depth in water of circular type,2
wheels,and 120 rpm,4cm depth in water of square type,same 2
wheels.There are very slight effective-ness turbidity,the water
comperative and the pH level due to virationof water wheels
during test.The solid segment will precipitate collected to
central parts in the buttom of the pond.The more precipitations
accumlated in central,the more high revolutions would taken by
machine.
