过氧化氢/铁活化过硫酸盐技术降解土壤中有机污染物的效果研究

Study on the effect of hydrogen peroxide and iron-activated persulfate technology on the degradation of organic pollutants in soil

过硫酸盐作为原位化学氧化技术中新兴的一种修复剂,在有机污染场地修复过程中应用广泛,但在使用过程中难免会对土壤产生二次污染,本文以某污染场地内污染土为依据,实验室自配污染土壤,研究分析过氧化氢/铁活化过硫酸盐技术降解土壤中有机污染物的效果,利用分段投加过氧化氢和过硫酸盐的方式,减小过硫酸盐药剂投加量,分析其污染物降解效果,进而达到降低二次污染风险,并保证污染物高效去除的效果。

As a new repair agent in situ chemical oxidation technology,Persulfate is widely used in the process of repairing organic contaminated soil.But in the use process will inevitably produce secondary pollution to soil.This article was based on a site in contaminated soil pollution.The effect of hydrogen peroxide/iron activated persulfate on the degradation of organic pollutants in soil was studied and analyzed in the laboratory.Using subsection adding hydrogen peroxide and persulfate,reduce persulfate drug dosing quantity,research and analysis the pollutants degradation effect,thus to reduce secondary pollution risk,and ensure the efficient removal of pollutants.
