The surroundings of the Pothong River basin have been bettered recently amid the vigorous campaign to protect the ecological environment in the Democratic People's Republic of Korea.
The Pothong River is a tributary of the Taedong River flowing through the capital Pyongyang.
Water lettuce and graphene photocatalyst net play an effective role in protecting the ecological environment of the river.
Water lettuce is an aquatic plant drawing the attention of many people as it purifies the water quality and is of high economic profit.
Researchers of Kim Il Sung University are actively promoting the introduction of water lettuce into the Pothong River basin by completing the industrial cultivation and processing techniques of the plant.
The new graphene photocatalyst net recently produced and installed in the Pothong River basin by the Sungni Raw Material Processing Factory is playing a big role in protecting the ecological environment.
The net based on advanced technology elevates the natural water quality purification function of the rivers.
The Pyongyang University of Architecture and other educational and scientific research institutions are intensifying researches to raise the ecological functions of the rivers.
Other researches are made to introduce the technique for culturing microbes that can dissolve contaminant under the water and to apply flocculant effective for improving the water quality.
The further the work for preventing pollution and improving environment is intensified, the more beautiful the landscape of the Pothong River will turn.
