| 摘 要： | 为了开发经济实用的二氧化氯消毒工艺,对电解法制备高纯二氧化氯工艺在水处理中的运用进行了研究。在最佳条件下,电解氯酸盐自动催化循环制备的二氧化氯纯度可达98%左右。通过二氧化氯杀菌除藻试验,讨论了二氧化氯用量以及原水pH对细菌、叶绿素a、藻类的去除率的影响。结果表明,二氧化氯用量在2 mg/L以上时,3者的去除率均达到90%以上。当二氧化氯用量为2 mg/L、原水pH为6～9时,3者的去除率不发生显著变化,并且二氧化氯的剩余质量浓度均控制在0.5 mg/L以下。消毒成本:生产1 kg二氧化氯成本可以控制在6元以内,当二氧化氯用量在0.5～2 mg/L时,1 t水的消毒成本为0.003～0.012元。 |
