Practicing green development to the end丨The integrated device of "algae water separation" put into Erhai environmental protection treatment

The beautiful and mysterious Erhai Lake in Yunnan is the second largest freshwater lake in Yunnan. It is a well-known plateau pearl. It has experienced large-scale blue-green algae outbreaks and experienced water quality deterioration. Comprehensive law enforcement and supervision in the watershed and national protection of Erhai Lake Under the action, the quality of Erhai Lake has returned to its former clear appearance in recent years, and a new journey of protection and management of the Erhai Lake and the transformation and development of the river basin have been started.

On September 22, the “algae-water separation” integrated device developed by the Institute of Hydrobiology, 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 continuously collect and treat cyanobacteria throughout the growth cycle, effectively controlling the bloom of cyanobacteria.

At the event site, according to Gong Yinfeng, the general manager of Changzhou Delofite Filtration System Co., Ltd., the experiment of this new technology in the Dabokou of Caohai Lake and Dongdahe Reservoir of Chengjiang in Kunming Dianchi achieved a set of 10,000 tons/day. The service area of the device exceeds 1 million square meters of water area. 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%.

Among them, the patented technology of algae slurry concentration structure composition has many advantages: low energy consumption for concentration, and the moisture content of the semi-solid phase algae slurry produced is less than 95%, which is convenient for collection, transportation and disposal, and is very beneficial to subsequent resource utilization. After treatment, the waste liquid is returned to the separator for separation; the algae water is separated thoroughly, and the equipment can continuously feed, separate, and continuously discharge the algae mud; the system has a high degree of automation, and the screen surface of the filter is automatically cleaned.

From regulatory agencies to mass netizens, from environmental protection to green ecology, people are very concerned about the changes in the quality of Erhai Lake and the supervision of Erhai Lake pollution. The green waters and green mountains are the golden mountains and silver mountains. We must not forget the ardent exhortations of "We must protect the Erhai Lake" and "Hold the Erhai Lake". We will unswervingly follow the path of ecological priority and green development, and promote the protection and governance of the Erhai Lake and the transformation and development of the river basin. All people participate , Erhai Lake protection and governance have achieved phased results.

It is reported that the "graphene micro-flocculation algae water separation technology" will be implemented in Erhai Lake. The technology has two invention patents and eight utility model patents. It is foreseeable that besides Erhai Lake, this new technology will be widely used in the future nationwide lake management, river management and other fields. It will play a huge role and show a huge benefit advantage!
