白腐真菌对煤泥水的絮凝效果研究

Study on the white-rot fungus' s flocculation processing slime water

从生物学角度出发研究了作为微生物絮凝剂产生菌的白腐真菌的培养特性,并找到了它的最佳培养条件;同时还对煤泥水中的煤泥颗粒组分进行了分析,发现其中有一半以上的颗粒粒度小于0.044mm,进而说明细粒在煤泥水中含量很大,不可能仅靠自身重力实现沉降;还对不同的因素与絮凝效果之间的关系进行研究,并整合归纳了能增强白腐真菌絮凝煤泥水的效果的条件.较强的热稳定性和较高的絮凝净化效果是白腐真菌的优点,如果加上某些阳离子,如二价钙离子,则对其有比较显著的助凝作用.白腐真菌在煤泥水絮凝方面的应用具有较好的发展前景.

From the biological point of view,this paper studies the culture characteristics of white rot fungi as a microbial flocculant producing bacteria and finds its best culture conditions;at the same time slime particles in coal slurry are analyzed.We find that more than half of the particle size is less than 0.044 mm,which shows that the particles in the slurry water content greatly,which means the sedimentation can not rely on their own gravity.In this paper,the re-lationship between different factors and flocculation effect are also studied.The conditions for the effect of the flocculation of coal slurry by white rot fungi are summarized.Stronger thermal sta-bility and higher flocculation and purification effect are the advantages of white rot fungi.Some cation such as two calcium ion has a significant effect on the coagulation.Therefore its develop-ment prospect is very considerable.
