The invention discloses a wastewater treatment device capable of preparing microalgae coagulation beads and a use method, and particularly relates to the technical field of wastewater treatment.The wastewater treatment device comprises a sewage cylinder pool, a bead preparation machine and a sewage inlet, and the bottom of the sewage cylinder pool is fixedly connected with a sewage discharge pipe communicated with the interior of the sewage cylinder pool; a bead waste treatment assembly for connection is arranged between the sewage cylinder pool and the bead preparation machine; through the arrangement of the throwing mesh frame, the rotating shaft column, the oscillating rod, the eccentric disc and the moving block, the throwing mesh frame, the rotating shaft column, the oscillating rod, the eccentric disc and the moving block can move in multiple directions in sewage, water flow can continuously rotate and roll along a spiral shape, sewage in different layers and areas can be fully mixed, microalgae coagulation beads can make more uniform contact with pollutants in the sewage, and the sewage treatment effect is improved. The collision probability of pollutants and microalgae coagulation beads is improved, it is ensured that bead bodies stay in the sewage cylinder pool for a long time, and therefore the removal process of the pollutants is accelerated, and the wastewater treatment quality is improved.

Resumen de: WO2025206966A1

The present invention refers to a biotechnological process for obtaining suspensions of biogenic nanoparticles of zerovalent selenium, which have a high stability, and which have agronomic functions specific to plant biostimulants, that are amplified as a result of the formation of a biocorona which includes bioactive molecules from the biotechnological system wherein these selenium nanoparticles were formed. The biotechnological process involves the biosynthesis of selenium nanoparticles by the consortium of microalgae, Nannochloris sp. 424-1, deposited under CCAP number 251/10 in the Culture Collection of Algae and Protozoa (CCAP), and yeasts, Rhodotorula mucilaginosa TazRr, deposited under DSM number 34804, at the Leibniz Institute DSMZ - German Collection of Microorganisms and Cell Cultures, to promote the formation of suspensions of stable selenium nanoparticles. The process also includes separation and concentration steps by micro- and ultrafiltration on ceramic membranes.

Resumen de: CN223397569U

The utility model provides an integrated bacteria-algae symbiotic system suitable for advanced sewage treatment, which is used for solving the problem that activated sludge can shield light of a light supplementing mechanism in the prior art. Comprising a first treatment tank, a stirring device, an aeration assembly, a water inlet formed in the bottom of the first treatment tank, a water outlet formed in the top of the first treatment tank, a mounting bracket arranged in the first treatment tank, a plurality of light supplementing assemblies and a plurality of microalgae assemblies, the light supplementing assembly is arranged in the bacteria and algae biological area, and the bacteria and algae biological area is far away from the bottom of the first treatment pond, so that the problem that large-particle pollutants or sludge in sewage is deposited on the light supplementing assembly to influence photosynthesis of bacteria and algae can be avoided. In addition, the sewage is stirred through the stirring device, mixing of the sewage, the activated sludge and the microalgae can be promoted, full contact of the sewage, the activated sludge and the microalgae can be achieved, and therefore the sewage treatment effect can be improved.
