Yunnan Province has introduced the world's most advanced technology to clear and dispose of the silt at the Dongfengba in the Dianchi Lake.
The dredging technology is environmentally friendly and the lake-bed silt after being treated is deposited in a special ground where trees are planted to prevent secondary pollution.
Compared with the conventional method, this technology is stable and has very good environmental effects with less investment.
