Title:
ECOLOGICAL SOFT ENCLOSURE FOR ALGAE AND SEWAGE INTERCEPTION AND PURIFICATION, AND CONSTRUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/238118
Kind Code:
A1
Abstract:
An ecological soft enclosure for algae and sewage interception and purification, and a construction method therefor. The ecological soft enclosure comprises an underwater low weir (6), pile bodies (1), a first soft enclosure (4) and a second soft enclosure (3), wherein the first soft enclosure (4) and the second soft enclosure (3) are arranged in a water body at an interval; the underwater low weir (6) is arranged at the bottom of the water body between the first soft enclosure (4) and the second soft enclosure (3); submerged plants (7) are grown on the underwater low weir (6); and attached algae membranes (5) are arranged on the inner side face of the first soft enclosure (4) and/or the second soft enclosure (3). According to the ecological soft enclosure for algae and sewage interception and purification, and the construction method therefor, the exchange of water bodies on the two sides of the enclosures is slowed down by means of the second soft enclosure (3) and the first soft enclosure (4), such that a water flow passes through the submerged plants (7) on the underwater low weir (6) to be subjected to nitrogen and phosphorus absorption and water quality purification, and secondary absorption of nitrogen and phosphorus is finally performed by means of the attached algae membranes (5), thereby greatly reducing the problem of eutrophication of the water bodies.
