Green Biotech Floating-island, GBC material
- Project contents
Large-scale biotech floating-island and GBC grand dam were constructed in the northwest part of Chaohu Lake.
Nanfei River: large indoor botanical garden with high-level water purification capability.
Nanfei River: Green Biotech Floating-island.
- Features of the project
It makes the muddy Nanfei River clean from the fountainhead, and the effects remain all the way till the northwest water area of Chaohu Lake.
By applying the bio-tech of Green Biotech Floating-island, it reduces the pollutant burden of the lake in a comparatively short time. Besides, it also restores the ecology, improve the self-purification capability and water quality of the lake.
When purifying and improving water in the polluted water areas, it also provides population with water landscaping and recreational places.
Besides, it can also produce some side benefits and contribute to the development of economy and society.
- Construction condition,
resultsThe feasibility report was submitted in October 2007.
It was approved by the National People's Congress of China in March 2008.
