SEAWATER PURIFYING EQUIPMENT

摘要

PURPOSE:To keep the quality of water in the semi-closed sea area around sewater purifying equipment without using a power source such as electric power by providing a purifying part performing the purification of seawater by a microorganism carrier and a retarding part storing seawater coming in getting over a breakwater to supply the same to the purifying part by difference in the water level. CONSTITUTION:Seawater purifying equipment A is constructed along the seashore of a sea area S and equipped with a breakwater permitting the passage of the waves W generated in the sea area S, the purifying part 4 provided on the land side of the bank 1 and constituted so as to be changed in its water level corresponding to the tide level of the sea area S and purifying seawater with the microorganism carrier arranged there and the retarding part 2 adjacent to the breakwater 1 on the land side thereof and storing seawater W getting over the breakwater 1 to supply the same to the purifying part 4 by difference in the water level. The seawater X getting over the breakwater 1 to flow in is stored to make the water level of the retarding part 2 higher than the tide level of the sea area S and supplied to the purifying part 4 by the difference in the water level between the retarding part and the purifying part 4 to be purified by the microorganism carrier in the purifying part.
