According to the invention, sewage treatment is carried out through a facultative bacteria + fungus + microalgae symbiotic aggregate structure, and the advantages of good purification treatment effect, fast treatment speed, good purification effect, low cost, no need of additional addition of a carbon source, reduction of the oxygen introduction amount of a sewage treatment system, simplification of the sewage treatment system, reduction of energy consumption, reduction of cost and the like are achieved.

METHODS FOR MANUFACTURING NUTRITIONAL ENHANCEMENT PRODUCT FOR LIVE FEED USING NUTRIENT-RICH MICROALGAE SCHIZOCHYTRIUM SP. BIOMASS

Resumen de: WO2025174210A1

The present invention relates to: a feed composition for zooplankton, comprising biomass derived from Schizochytrium sp. microalgae; a method for culturing zooplankton using same; and an aquaculture method for fish or crustaceans. The biomass derived from Schizochytrium sp. microalgae of the present invention has the effect of nutritionally enriching zooplankton, and when zooplankton fed with the biomass is fed to fish or crustaceans, growth of fish or crustaceans is promoted and non-specific immunity is enhanced, and thus the biomass can be effectively used as a feed composition or a feed additive.

Rural sewage microalgae treatment device

Resumen de: CN223239906U

The utility model discloses a rural sewage microalgae treatment device, which belongs to the technical field of sewage treatment, and comprises an algae box and a peristaltic pump, the top of the algae box is provided with a first illumination component, one side of the algae box is provided with a plurality of circulation ports, the other side of the algae box is provided with a discharge port, the circulation ports are fixedly connected with a circulation component, and the discharge port is provided with a discharge port. A bracket is arranged at the bottom of the circulating assembly, a second illumination assembly is arranged at the top of the bracket, and a mixing assembly is arranged in the circulating assembly. The first illumination assembly and the second illumination assembly are arranged, sewage in the algae tank is irradiated by the LED lamp post, the mixing assembly is continuously irradiated by the LED lamp strip, sufficient illumination on algae is achieved, under the combined action of the circulating assembly, the mixing assembly and the peristaltic pump, the mixing time of the sewage can be prolonged through the mixing pipeline, and the mixing efficiency is improved. Under the guiding action of the spiral blade, the water flow rotates, and the algae and the sewage are mixed by the rotating water flow, so that the effects of fully mixing the sewage and improving the mixing efficiency are realized.
