改性铝土矿与其它混凝剂净水性能对比的研究

Compare the Flocculants Performance for Modified Bauxite with Other Inorganic

改性铝土矿做净水剂，与市售其它混凝剂比较，具有pH值适用范围宽、对水中阴阳离子，尤其是对SO_4^(2－)的吸附能力强等优点。去除水中的浊度、颜色、COD等同于市售其它混凝剂。

The modified bauxite and inorganic flocculants on the turbidity removing,the appropriate pH range, COD removing, color sludge dewatering have been compared inthis paper. The experiment results indicated that mudified bauxite is more advandtagesthan other inorganic flocculants in water treatment, such as less price, wide spectrum ofpH, high removal efficiency in turbidity, color and COD less Al3+ remains in water and itshydrolysis product with satiscutory dehydrolysis SO_4^(2-). This new material is a water treatment reagent which is high efficient and widely applied.
