PURPOSE: A lake purification apparatus and method are provided to remove organic and inorganic materials, algae, and phosphorus contents which is a growth factor of the algae from raw water to maintain the clean condition of lakes. CONSTITUTION: A lake purification apparatus includes a raw water pump(10), a drug insertion device(20), an algae removal device(30), a phosphorus removal device(40), a filtration device(50), a pressurizing flotation device(60), and a dehydration device(70). The drug insertion device inserts a coagulant into inserted raw water for producing precipitates. The algae removal device emits radio waves for killing algae from the raw water. The phosphorus removal device reacts phosphorus in the raw water with dolomite to form precipitates. The filtration device filters the coagulated precipitates, phosphorus precipitates, and dead algae. The pressurizing flotation device separates floating solid parts from the filtered water. |
