A kind of preparation method of the base of seaweed containing grease water-purifying material

The present invention relates to environmental technology field, specifically a kind of preparation method of the base of seaweed containing grease water-purifying material.By Lipid-producing seaweed according to 0.1-0.2g L ‑1 Inoculum concentration be added in sea water medium, under 10-20 DEG C, the condition of culture that Light To Dark Ratio is 12h:12h, culture to Lipid-producing seaweed enters logarithmic growth phase latter stage, add the poor Nutrient Stress sea water medium isometric with cultivating system, then then at 10-20 DEG C, under conditions of Light To Dark Ratio is 12h:12h, carry out poor Nutrient Stress culture stimulation energy algae oil-producing, to algae fat content > 10%, it adds aluminium polychloride and nano ferriferrous oxide mixture stirs coagulation, the seaweed containing grease of collection is put into steam blasting device, carries out steam blasting broken wall treatment；It is then added into chitosan-cetomacrogol 1000 dilute acid solution, stirs and evenly mixs, collect modified algal biomass, it is dry, the base of seaweed containing grease water-purifying material is made.Material of the present invention can remove the base water-purifying material of seaweed containing grease of a variety of organic or inorganic pollutants.
