Description
技术领域technical field
本发明涉及环境工程领域，尤其涉及一种基于原位热脱附(In Situ ThermalDesorption，ISTD)的烃类污染土壤修复系统。The invention relates to the field of environmental engineering, in particular to a hydrocarbon-contaminated soil remediation system based on in situ thermal desorption (In Situ Thermal Desorption, ISTD).
背景技术Background technique
当今，环境危机问题日益增强，已发布的《全国土壤污染状况调查公报》显示，超三成土地受到侵蚀，近五分之一耕地遭污染。土壤污染直接导致农作物的减产，生物品质不断下降，严重威胁人体健康。国家最新生态环境保护规划中，要求在部分污染地块集中分布的城市，要规范、有序开展再开发利用污染地块治理与修复烃类污染物。烃类污染物在一定条件下直接从土壤中解吸附，产生挥发性的有机化合物(Volatile Organic Compounds,VOCs)，而VOCs对增强大气氧化性的作用比氮氧化物NOx更加重要，是造成严重雾霾污染的最重要污染物。如果任凭烃类污染物在土壤中聚集，会严重污染环境卫生，造成能源浪费，安全隐患以及经济损失等一系列问题，对人类生命健康造成了威胁。Today, the environmental crisis is increasing. The published "National Soil Pollution Survey Bulletin" shows that more than 30% of the land has been eroded, and nearly one-fifth of the cultivated land has been polluted. Soil pollution directly leads to the reduction of crop production and the continuous decline of biological quality, which seriously threatens human health. In the latest national ecological and environmental protection plan, cities that are concentrated in some polluted land are required to standardize and orderly carry out the redevelopment and utilization of polluted land to treat and repair hydrocarbon pollutants. Hydrocarbon pollutants are directly desorbed from the soil under certain conditions to produce volatile organic compounds (Volatile Organic Compounds, VOCs), and VOCs are more important than nitrogen oxides (NOx) in enhancing atmospheric oxidation, which is the cause of severe fog. The most important pollutant of haze pollution. If hydrocarbon pollutants are allowed to accumulate in the soil, it will seriously pollute environmental sanitation, cause a series of problems such as energy waste, safety hazards and economic losses, and pose a threat to human life and health.
土壤气相抽提SVE技术是当前有机污染物土壤处置技术中十分有效的技术之一。在修复过程中，为提高SVE技术的工作效率，经常采取对污染场地加热的方式，使有机污染物从污染介质中快速分离，以缩短修复周期。但目前的土壤气相抽提SVE技术多采用真空设备产生负压驱使空气流过土壤孔隙，从而夹带VOCs流向抽取系统，处理过程中控制不合理，存在很大的安全隐患。Soil gas phase extraction (SVE) technology is one of the most effective technologies in the current soil disposal technology of organic pollutants. In the remediation process, in order to improve the working efficiency of SVE technology, the method of heating the contaminated site is often adopted to quickly separate the organic pollutants from the polluted medium to shorten the remediation period. However, the current soil vapor extraction SVE technology mostly uses vacuum equipment to generate negative pressure to drive air through the soil pores, thereby entraining VOCs and flowing to the extraction system. The control process is unreasonable, and there are great safety hazards.
