摘要
近年来,原位化学氧化技术中的过硫酸钠作为一种新兴的氧化剂受到越来越多的关注。本文围绕土壤修复过程中原位化学氧化过硫酸钠的使用,探讨了修复过程中产生的硫酸盐在自然环境中的分布及对人类活动的影响,说明了土壤生物修复特征污染物受硫酸根离子的影响,并且对硫酸盐还原菌及其对环境及土壤修复的影响进行了讨论。结果表明,在原位化学氧化土壤修复技术中过硫酸钠的使用,不会对污染场地的后续使用带来影响。
Sodium persulfate method is emerging in recent years of in situ chemical oxidation（ ISCO ） soil remediation. Focus on the use of sodium persulfate during ISCO soil remediation, this paper discussed the influence of sulfate ion in natural environment and human activity, illustrated the theory of how sulfate join the reaction about characteristics pollutants in bioremediation. Sulfate reducting bacteria and the ad- vantages and disadvantages to environment and soil remediation were also discussed. It can be sure that the use of sodium persulfate in ISCO soil remediation would not impact the subsequent use of the contaminated site.
