摘要: 本文建立了一种利用生物质炭并结合过氧化氢对火电厂多环芳烃(PAHs)污染土壤的修复方法.采集诸城火电厂多环芳烃污染土壤为研究对象,采用盆栽试验的方法,研究了不同梯度生物质炭与过氧化氢配合施用修复多环芳烃污染土壤,对小白菜生长指标及土壤多环芳烃含量的变化.结果表明,合理施用生物质炭配施过氧化氢能促进小白菜生长,有效降低土壤和小白菜中多环芳烃含量.与T1(不施生物质炭)对比,生物炭处理的小白菜生物量增加8%—15%,叶绿素SPAD值增加25%—50%,荧光参数和光谱反射率有一定提高,小白菜和土壤多环芳烃含量显著减少.同时,使污染酸化土壤pH值提高了0.2—0.6个单位,土壤有机质含量提高了9.5%—45.6%,碱解氮、速效磷与速效钾等养分有一定量的增加.其中,T7(0.5‰ H2O2+2‰生物质炭)处理修复效果最好,供试蔬菜和土壤中多环芳烃去除率分别达到了69.6%和58.8%.其次是T3(2‰生物质炭)处理,供试蔬菜和土壤中多环芳烃去除率分别达到了42.9%和54.6%,也具有较好的去除效果.因此,可推荐在修复实践中参考应用.Abstract: In this paper, a method for remediation of polycyclic aromatic hydrocarbons (PAHs) contaminated soil by biochar and hydrogen peroxide has been established. The contaminated soil was collected in farmland near thermal Power Plant in Zhucheng City, Shandong Province. Pot experiments were conducted to study the effects of different amount of biochar combined with hydrogen peroxide on Chinese cabbage growth and PAHs content. The results showed that proper application of biochar and H2O2 could promote the growth of Chinese cabbage and effectively reduce the content of PAHs in soil and Chinese cabbage. Compared with T1 (no biochar), the biomass of Chinese cabbage increased by 8%-15%, and the SPAD value increased by 25%-50%. The Chinese cabbage's fluorescence parameters and spectral reflectance were improved, and the content of PAHs in Chinese cabbage and soil decreased significantly. Moreover, the pH of acidified soil increased by 0.2-0.6 units, the content of soil organic matter increased by 9.5%-45.6%, and the nutrients such as available phosphorus and available potassium increased to a certain extent. Among treatments, T7 (0.5‰ H2O2+2‰) had the best remediation effect, and the removal rates of PAHs in tested Chinese cabbage and soil reached up to 69.6% and 58.8%, respectively. In addition, T3 (2‰ biochar) also had good removal effects, and the removal rates of PAHs in tested Chinese cabbage and soil reached were 42.9% and 54.6%, respectively. Therefore, it is recommended to refer to the application in the practice.
