Graphene micro-flocculation algae water separation technology will be used for the first time in Erhai to remove cyanobacteria

On September 22, with 2 national invention patents and 8 utility model patents, the "algae water separation" integrated device led by the Institute of Hydrobiology of the Chinese Academy of Sciences was put into the Erhai Lake environmental protection treatment at Taoyuan Wharf in Dali City. This new technology for the treatment of cyanobacteria blooms-"graphene micro-flocculation algae water separation technology" can be collected and treated uninterruptedly during the full growth cycle of cyanobacteria, which can effectively control the outbreak of cyanobacteria blooms. The application of this new technology will hopefully give a brand-new treatment condition to the waters where cyanobacteria occur.

At the scene, the reporter saw that the ship equipped with this technology was put into the Erhai Lake, and the cleanup work will be carried out in accordance with the process. Some staff members are very happy with the use of this technology. Gong Yinfeng, general manager of Changzhou Delofite Filtration System Co., Ltd., said: “Today is a day of great significance for the environmental protection industry, for the treatment of lakes, especially for the treatment of cyanobacteria blooms. Today is a new kind of treatment of cyanobacteria water. Hua's technological process-"graphene micro-flocculation algae water separation technology" will be implemented in Erhai Lake. This technological process has two invention patents and eight utility model patents. Its remarkable feature is that it can be used in the entire growth cycle of cyanobacteria. Continuous and uninterrupted collection and treatment. It is not affected by the density of algae and can be operated around the clock. Therefore, continuous operation with this technology can completely prevent the outbreak of blue algae blooms. Unlike the traditional algae fishing process, it can only handle Concentrated algae are salvaged after the cyanobacteria bloom, which can only be a follow-up remedial treatment for the destroyed environment. Compared with the traditional algae fishing process, this new technology has a small investment (compared to the traditional The deep well air flotation process saves investment by more than 60%), high efficiency (compared to the traditional deep well air flotation process, the efficiency is increased by 200%), and the treatment cost is low (compared to the traditional deep well air flotation process to reduce the water treatment cost by 50%). It is foreseeable that besides Erhai Lake, this new technology will be widely used in lake management and river management across the country in the future, and will play a huge role."

Gong Yinfeng said, "The traditional algae fishing process can only process dense algae, and it is salvage after the cyanobacteria bloom erupts. This can only perform subsequent remedial treatments for the deeply damaged environment. Graphene microflocculation algae water separation technology Unaffected by the density of algae, the all-weather operation separates the algae cake with 90% water content and clean water. This new technology process has obtained a set of 10,000 tons in the experiment of Dabokou Caohai Dabokou and Chengjiang Dongdahe Reservoir in Dianchi Lake, Kunming. Compared with the traditional deep-well air flotation process, it has the advantages of saving investment by more than 60%, increasing efficiency by 200%, and reducing treatment costs by 50%.
