- 摘要：
PROBLEM TO BE SOLVED: To provide a method and an apparatus for cleaning rearing water of an aquatic life, dispensing with the use of chemicals and a complicate operation management, effective for suppressing the increase of the turbidity and color of the water, eliminating proteins, total nitrogen, ammoniacal nitrogen and nitrite-nitrogen from rearing water and automatically keeping the water to neutral state by preventing the lowering of the pH of the water to be treated.
SOLUTION: The rearing water cleaning method comprises a filtering step to use sand as the filtering material in the cleaning of rearing water 2, a pH adjusting step to use oyster shell and a foam separation step. The foam separation step performs foam separation treatment of the rearing water 2 by supplying a gas to the rearing water 2 in a separation tank 7, the gas is supplied to the separation tank 7 in the form of fine bubbles, the fine bubbles are formed by generating bubbles by a means for exclusively generating bubbles and then dividing the bubbles generated by a bubble-shearing means and/or formed by the bubble-shearing means itself, and the fine bubbles are used in the step to perform the foam separation treatment of the rearing water.
