| 摘要: |
| 为了去除地表水源水加标模拟的重金属铊(Tl)和锑(Sb)复合污染,采用了高锰酸盐复合药剂(PPC)和聚合硫酸铁(PFS)联用强化常规工艺;通过静态烧杯实验和微型移动式平台优化工艺参数,对去除铊和锑复合污染的影响因素(PPC投量、PFS投量和pH)进行分析．实验结果表明,组合工艺可保证水源水在Tl超标2～3倍(0.21～0.35 μg·L-1),Sb超标3～4倍(15～20 μg·L-1)的场合出水达标,对应的工艺参数是: pH控制在5.7～6.3,PPC投量控制在3 mg·L-1以上,聚铁投量控制在40 mg·L-1以上．PPC和PFS联用强化常规工艺可有效去除地表水源水加标模拟的铊(Tl)和锑(Sb)复合污染,并且PPC投量是影响Tl去除的主要因素,PFS投量和pH是影响Sb去除的主要因素． |

| Abstract: |
| An integrated approach of potassium permanganate composites and polymeric ferric sulfate was used to strongthen the effect on the removal of simulated thallium and antimony combined pollution in surface water. Jar tests and micro-travelling experimentation platform tests were used to optimize the operation conditions, then the main factor for removing thallium (Tl) and antimony (Sb) combined pollutants was discussed. The results show that the initial water containing 0.21-0.35 μg·L-1 (2-3 times) thallium(Tl) and 15-20 μg·L-1 (3-4 times) antimony (Sb) can be treated to satisfy the Chinese drinking water quality standard, simultaneously the corresponding operation condition are as follows: the pH value of raw water should be adjust to 5.7-6.3, the dose of PPC was higher than 3 mg·L-1 and a dosage of PFS was higher than 40 mg·L-1. And furthermore, the dosage of potassium permanganate composites(PPC) was the key factor for thallium(Tl) removal,while the dosage of polymeric ferric sulfate(PFS) and pH of raw water were the key factors for antimony(Sb) removal. |
