<p>An advanced purification system, wherein a closed water area surrounded by dam bodies, bulkheads, shallow areas, and land areas is formed on the outside of a water area having a varying water level and closed by damp bodies called a "void of water area" formed of catalytic oxidation banks with a large number of voids to purify the water area. The system comprises a purified water reservoir (3) having a purification water rate Qc at which clean water is discharged to an outer water area when a water level in the outer water area lowers and a sufficiently storable storage capacity Qb. The relation between Qb and Qc is Qb > Qc. Where a total water pollution occurrence amount including the inflow of water in the water area of the purified water reservoir (3) is Sigmabi = B and the total purification capacity in the "void of water area" is Sigmaci = C, when the water level in the outer water area (4) rises under the conditions of B/C <= 1, clean water stored in the purified water reservoir (3) is permeated again through the catalytic oxidation banks (1) and flows to the inside (2) of the "void of water area" to further clean water inside (2) the "void of water area". By repeating this operation, the water inside (2) and outside (3) the "void of water area" can be further purified to highly purify the water inside (2) the "void of water area".</p> |
