New method of inhibition of lake algae North Water Diversion Project For a nest
HC Environmental Network Between the lake and the Yangtze River each year about 500 million to 1 billion cubic meters of exchange of water, two to three years lake water is essential for it again. So many fresh running water into the lake, can significantly change the water quality of Chaohu Lake. Thus, four to five years, the water can Chaohu from the current five to four or more, you can make lake water clear and effective containment of the outbreak of cyanobacteria. Reporter learned yesterday from the Provincial Development: The subject of concern to people throughout the province, "cited Yangtze River to the nest" argument works being studied.
According to reports, the total area of 13,486 square km Chaohu Lake Basin, the total cultivated land 660 mu, with a total population of 700 million people, Hefei, Chaohu City, which is located. Although the lake basin area accounts for only 10% of the province, but the economic and social development in the province's status and role is very important.

After the two lines into the lake by lake Chujiang lines are gate or cattle through the Yuxi River Road, Tuen Mun River flood diversion into the Yangtze River, the river and the lake of gravity to achieve, since the row. Combination of channel construction, the two programs are expected to invest an initial estimate of about 3 billion yuan, 50 billion. Comparison of the two lines quoted Jiang
can be found: rapeseed Lake Lake line more than the white swing invest about one billion to 15 billion; rapeseed cited downstream the lake line in the upper lake than swing line White River cited a long time, can be water quantity and improve the Water Environment The effect is obvious; rapeseed Lake line normal to navigation along the flood control and drainage on little effect. River occurred in heavy rain, the white swing by the lake via the River Line, MB River levee flood control and the pressure increased. Comprehensive analysis, "North Water Diversion Project Proposal nest" recommended rapeseed Lake line.
