METHOD FOR FILTERING SEA WATER FOR RED TIDE CONTROL

摘要

PURPOSE: Provided is a method for filtering sea water for red tide control, wherein sea water is filtered by a plurality of filter layers to remove plant plankton and foreign matters and oxygen is supplied to the filtered sea water. CONSTITUTION: The method comprises the steps of filtering sea water through a fine sand layer(231), a coarse sand layer(232) and a gravel layer(233) in order to remove red tide; filtering the sea water through a first large gravel layer(234), a first activated carbon layer(235) and a second large gravel layer(236) to activate the sea water; filtering the sea water through a second activated carbon layer(237), a porphyry layer(238) and a charcoal layer(239) to remove germs in the sea water and further activate the sea water; sterilizing the filtered sea water by electrolysis; mixing the sterilized sea water while supplying oxygen to the sea water; and supplying the oxygen-rich sea water to an aquafarm.
