Title:
SYSTEM FOR IMPROVING TOTAL WATER QUALITIES IN EUTROPHICATED AND CONTAMINATED WATER AREA UTILIZING WATER PURIFYING FUNCTIONS OF VARIOUS PLANTS AND MICROORGANISMS
Document Type and Number:
WIPO Patent Application WO/2008/081554
Kind Code:
A1
Abstract:
A system for improving the total water qualities in an eutrophicated and contaminated
water area utilizing the water purifying functions of various plants and microorganisms
which comprises: a floating island with plants to be floated on the water surface
of a lake, a lagoon, a pond, a river or the like having been eutrophicated (i.e.,
being rich in phosphorus, nitrogen and so on) and contaminated with domestic
waste water flowing thereinto wherein plants, which have functions of absorbing
eutrophication components from the roots and thus purifying water, are planted
and grown; an anchor for fixing the floating island with plants to the bottom;
a weight for controlling the floating conditions of the floating island with
plants; and a connecting member for connecting the floating island with plants,
an anchor and a weight, wherein an aquatic plant or an aerobic or anaerobic microorganism
capable of absorbing eutrophication components is stuck to at least any of the
lower part of the floating island with plants, the anchor, the weight and the connecting
member in a manner suitable for the environmental conditions of the water area
in which the system is provided, thereby achieving an effect of improving the
water qualities simultaneously at all of the water face, the underwater part
and the bottom.
