本課題的研究內容包括：從微生物樣品來源中篩選出微生物絮凝劑；從中挑選具有優良絮凝活性的微生物絮凝劑產生菌，對其產微生物絮凝劑的培養條件進行優化以提高其產絮凝劑的絮凝活性；用該絮凝劑絮凝高嶺土懸液，並與聚合鋁（ pac ）和水解聚丙烯酰胺（ hpam ）進行比較，以考察其對廢水的絮凝效果；在具有優良絮凝活性的基礎上，將該絮凝劑提取和純化，對其進行分析研究，並對其絮凝機理進行探討。Effects of rare earth elements on mechanical properties of industrial pure aluminium
稀土元素對工業純鋁機械性能的影響Pure re ( cerium, lanthanum ) have certain improvement effect on the conductivity of pure aluminum with relatively high impurity contents in some degree of addition, but had a slight effect on that with relatively low impurity content
單獨加稀土鈰或鑭對雜質含量高的純鋁的導電性在一定的添加范圍內有一定的改善，而對雜質含量較低的純鋁的導電性略有改善。As to aluminum with the same purity, pure re elements have better effects than mixed ones
對同一純度的鋁而言，單一稀土對其導電性的影響優于混合稀土。Mixed re elements could improve the conductivity of pure aluminum with relatively high content of impurities, but had little effect on that with relatively low impurity content
混合稀土對雜質含量較高的純鋁的導電性有改善，對雜質含量低的純鋁的導電性基本不起作用。分享友人
