Claim:
1. A carbon dioxide concentration reactor using magnesium ions in seawater, wherein calcium oxide (CaO) or alkaline waste containing calcium oxide is injected into the seawater to allow the calcium oxide to react with magnesium ions present in the seawater to form magnesium hydroxide (Mg(OH) 2 ) for precipitation, after the precipitation of magnesium hydroxide, a supernatant of the seawater is removed and a lower layer liquid of the seawater containing the magnesium hydroxide and carbon dioxide are allowed to react with each other to convert carbon dioxide into concentrated seawater containing bicarbonate ions (HCO 3 − ) having a higher concentration than in a natural state, wherein the concentration reactor comprises:
