摘要：

利用微生物氧化亚铁硫杆菌(T.f.)为催化剂,催化氧化Fe²⁺为Fe³⁺制备了聚合硫酸铁(PFS)。并研究了氧化亚铁硫杆菌制备聚合硫酸铁的最佳工艺条件,在最佳工艺条件下制备的聚合硫酸铁具有较好的絮凝效果和对城市污水较好的去浊率。该方法生产工艺简单、成本低、无污染、不残留有毒物质,具有良好的经济和环境效益。

Abstract:

Microbe,thiobacillus ferrooxidans (T. f.) has been used as catalyst. Polymeric ferric sulphate(PFS) has been prepared by catalysis-oxidation of ferrous to ferric ion,and its optimum technological conditions are studied. The PFS prepared under the optimum conditions has good coagulation effectiveness and good removal rate of turbidity in the treatment of municipal wastewater. This method is characterized by simple technology,low cost,no pollution,and no poisonous substances residued,and has excellent economic and environmental benefits.

Key words: thiobacillus ferrooxidans, catalysis-oxidation, polymeric ferric sulfate
