摘要
采用固-液两相喷雾反应器在液相[枯草芽孢杆菌(K菌)和光合细菌(G菌)质量配合比为1∶5,含量10%(wt,质量分数),聚丙烯酸钠含量0.1%(wt,质量分数),营养剂含量10%(wt,质量分数)]∶复合非金属矿物(A)=1.0∶0.5条件下,制得固定化复合菌材料(ICM),并研究其对污染底泥及其上覆水体的处理效果。结果表明:ICM能使上覆水体化学需氧量(COD)、氨氮量(NH3-N)和总磷量(TP)的去除率分别达到58.2%、39.7%和50.0%,底泥颜色由黑色转变为黄褐色,臭味减轻,土壤环境得到改善,并对底泥的有机质去除率达到58.3%,水质得到改善。
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.
