摘　　要： 通过驯化培养以硫为电子供体的自养菌,考察硫自养菌降解高氯酸盐的效果。利用序批式试验,研究初始pH、生长温度、泥量和溶解氧等因素对ClO4-降解效果的影响,确定最佳优化控制条件。结果表明,在30℃、初始pH为7.0的厌氧条件下,添加270 mg/L硫粉,0.64 g/L厌氧培养的活性污泥能在15 h内将质量浓度15 mg/L ClO4-完全降解。 The potential of autotrophic bacteria to treat perchlorate contaminated water using sulful as electron donor was investigated in this study. Factors such as initial pH, temperature, domesticated sludge concentration, co-anions such as nitrate, chlorate, phosphate and dissolved oxygen affecting the removal of perchlorate were studied in detail by shaking bottle point tests. Results showed that 15 mg/L perchlorate was completely reduced by 0.64 g/L of domesticated sludge added with 270 mg/L of sulfur under the conditions of 30℃ and initial pH 7.0 within 15 h.
