Method for improving the phosphorus elimination capacity of a lake.

摘要

A method of improving the phosphorus elimination capacity of a lake (11). A flexible wall (16) is extended from the bottom (21) of the lake a substantial distance toward the surface (23) of the lake at the beginning of the vegetation period of the lake to separate the lower parts of a minor portion of the lake from the lower parts of the rest of the lake. Sheets (18) are positioned between an inlet channel (12) and the flexible wall (16) as growth areas for algae. The flexible wall (16) is lowered around the end of the vegetation period to allow the flushing away of sedimented algae from the bottom of the minor portion of the lake.
