Produced Organic Algae Screening and Research on the Applying in the Denitrifying Water Treatment

Using the BG-11 medium ,the usual cultivation of alage medium, fast and efficient screen a produced organic algae from the soil around a Chemical factory's soda production work-shop in Beijing.Experiments show that after 15 days cultivating,t-he algae's biomass reachs to maximum;the best yield conditions of the algae in the laboratory:Na2CO3 concentration(20mg/L),lig-ht intensity(4500Lux),inoculums size(10%),temperature(26℃).In its best sugar yield conditions,domesticate it by using different salinity inorganic mediums and simulation wsterwater and denitrifying bacteria medium.The polysaccharide concentration reachs to 8.6mg/L.Through the domestication,making it possible to use the organic products as the denitrifying bacteria's external carbon source in the denitrifying water treatment.It has good prospects for industrial application.
