Abstract: From the microbiological point of view,the solid liquid two-phase spray reactor was used when liquid phase composition (Bacillus subtilis(K bacteria)and photosynthetic bacteria ratio(G bacteria) 1∶5,content 10wt%,sodium polyacrylate content 0.1wt%,nutrient content 10wt%):composite non metal mineral (A) =1.0∶0.5,immobilized compound bacteria material(ICM) was prepared.The treatment effect of material on polluted sediment and its overlying water was studied.The results showed that the removal rates of chemical oxygen demand(COD),ammonia nitrogen (NH3-N) and total phosphorus (TP) in the overlying water were 58.2%,39.7% and 50.0% respectively.the color of sediment changed from black to yellow brown,the odor was reduced,the soil environment was improved,and the removal rate of organic matter reached 58.3%,indicating that the treatment of water was good.
