ECOLOGICAL FLOATING ISLAND FOR WATER PURIFICATION BY AIR-LIFT

摘要

An artificial plant island for water purification by aeration is provided to purify water by using aquatic plants and to improve ecosystem of lakes, marshes and natural view. An artificial plant island(A) for water purification by aeration includes a vegetation part(20) rearing plants(12) and a water purification device(30) purifying water. The water purification device includes a purifying aeration pipe for airlift pumping(31) extended to the bottom of the water of lakes and marshes(10). An aeration pipe(33) is installed on a purification aeration pipe, and a discharge pipe(34) is combined on an outer side of the aeration pipe. A water jacket(35) is formed on the top of the purification aeration pipe. An air aeration nozzle(15) sprays the air by supplying the air through an air supply pipe(14). The discharge pipe includes a discharge expansion pipe(341), the aeration pipe includes an aeration expansion pipe(331). An elastic operation part(32) is installed the top of the water purification device.
