Background

In 2007 for 5-6 months, severe blue algae pollution is caused by the outbreak of Taihu lake of Jiangsu in China, which causes the pollution of tin-free city tap water. In recent years, due to rapid development of industry, over 66% of lakes and reservoirs in China are in eutrophication level, wherein the eutrophication and the over-eutrophication account for 22%. The direct consequence of lake eutrophication is that blue algae is propagated in large quantity, the water quality is deteriorated due to the blue algae outbreak, the lake water source can not be used, and the water use crisis is easily caused if no emergency water source exists locally.

At present, the blue algae is mainly treated by adopting a salvaging mode in China and then further treated. The water content of the salvaged blue algae is about 99.4 percent, the water content of the blue algae after being treated in the algae-water separation station is 85 to 90 percent, the transportation cost is high, and the subsequent treatment and disposal difficulty is high. In recent years, the blue algae mud deep dehydration technology is continuously developed, 50% -60% of the blue algae mud is deeply dehydrated, the volume and the amount are greatly reduced, and the transportation cost is reduced, and the subsequent treatment difficulty is also reduced.

Through search, Chinese invention patents with patent number ZL201811322717.2 and grant publication number CN 109336360A disclose a blue algae deep dehydration method and a power generation energy method thereof.
