摘要
利用某实际污染场地土壤和实验室模拟污染土壤,开展装潢垃圾-土壤共处置体系对污染物无害化、稳定化作用效果的批次试验,采用表观去除率和真实去除率对该共处置体系对土壤中污染物的去除效果进行评估。结果表明:该共处置体系对有机污染物和重金属均具有一定的去除效果,反应进行到28 d时,总石油烃、苯酚类、苯系物、菲有机污染物的表观去除率分别为73.7%、79.7%、82.1%和67%,除乐果外大部分有机污染物的真实去除率均在40%~60%之间;5种重金属的表观去除率均在68%以上,其中可交换态和碳酸盐结合态的重金属含量在试验后期接近于零;该共处置体系中羟基(-OH)官能团、木质素、吸附-降解作用和碱性环境是实现污染物无害化的主要因素。该研究可为固体废物消纳和共处置提供思路和技术支撑。
This paper applies batch tests to investigating the harmless stabilization effect of pollutant remov al through co-disposal of decorating waste and contaminated site soil/ lab-contaminated soil, and applies the 28-day apparent removal rate and the true removal rate to evaluation. The results show that the system has certain removal effects on organic pollutants and heavy metals.The 28-day apparent removal rates of petro leum hydrocarbons, phenols, benzenes and phenanthrene are 73. 7 %,79.7 %,82. 1 % and 67 %, respectively. Real removal rate ranged between 40% and 60 % except for Rogor. More than 68 % of all the five heavy metals has been decreased, while the exchangeable fraction and carbonates bound fraction was hardly detec ted in the extract. The alkaline environment, adsorb-degradation and lignin should be the main contribu tors ? The study can provide ideas and technical support for solid waste cancellation and co-disposal.
