Soil Removal清除土壤

• Contamination that is small in area or unresponsive to in-situ technologies is a good candidate for soil excavation.污染，是小面积或反应迟钝原位技术是一个很好的候选土体开挖。 You can remove contaminated soil from a property using a backhoe or shovel and put the soil in buckets, drums or roll-offs.您可以删除从使用的反铲或铲的财产受污染的土壤和土壤桶，鼓或滚权衡。 Some landfills will accept contaminated soil depending on the type and severity of the impact, or you can send the soil to a treatment facility that can clean it and make it reusable.一些垃圾填埋场将接受污染的土壤的类型和严重程度的影响，或您可以发送土壤处理设施，可以清洁并使其可重复使用的。 Soil removal works for a variety of situations but it may become expensive if the contamination is widespread or severe.土壤拆除工程的各种情况，但它可能会成为昂贵的，如果污染是普遍或严重。

Soil Vapor Extraction土壤气相抽提

• Soil vapor extraction, also known as soil venting or vacuum extraction, is a popular method of treating volatile and semi-volatile organic compounds in soil.土壤蒸气萃取，又称土壤通风或抽真空，是一个常用的方法处理土壤中的挥发性和半挥发性有机化合物。 An SVE system consists of a series of vacuum extraction wells placed throughout the contaminated zone. SVE系统由一系列提取置于整个受污染区域的真空井。 A vacuum pump pulls air through the area, volatilizing the organic compounds and removing the vapors from the subsurface.真空泵拉通过该地区的空气，挥发的有机化合物和删除的蒸汽从地下。 This technology works well in permeable soil, such as sand or soil combinations with a high sand content.该技术的工作原理以及在渗透土壤，如沙含量高的沙或土壤组合。 SVE is generally a cost-effective option and is proven to work well and quickly. SVE通常是一个成本效益的选择，是证明的工作，并迅速。 A final remedial stage of natural attenuation -- reduction by natural processes such as biodegradation -- is common with SVE projects.最后的补救 - 减少自然过程，如生物降解 - 自然衰减阶段是共同SVE项目。

Phytoremediation植物修复

• Phytoremediation is the use of plants to remove contamination from subsurface soil.植物修复是利用植物，从地下土壤中删除的污染。 The plants will uptake soil pollution through their root system to remove the contamination in the area.工厂将通过他们的根系统吸收土壤污染，以消除该地区的污染。 Phytoremediation is visually pleasing because it often involves planting many shrubs, trees or flowers in the contaminated zone.植物修复是赏心悦目，因为它常常涉及到种植在受污染区域的许多灌木，乔木或花。 Many plants are effective for a variety of pollutants, making phytoremediation a good alternative for sites that are abandoned or areas that do not have surface obstructions.许多植物对多种污染物的有效，使植物修复一个被遗弃或不具有表面障碍物的地区网站的很好的替代品。

Natural Attenuation自然衰减

• Natural attenuation, or monitored natural attenuation, is a remedial method where constituents naturally degrade.自然衰减，或监控的自然衰减，是一种补救方法，其中成分的自然降解。 You can boost natural attenuation in an area by injecting microorganisms that feed on the pollutants or air that increases their activity to help break down the contamination.在一个区域，您可以提高注入微生物对污染物或空气，增加他们的活动，以帮助打破污染的饲料的自然衰减。 Natural attenuation works well for organic contamination such as fuels and solvents that readily degrade.如燃料和溶剂，容易降解的有机污染物的自然衰减效果很好。 Routine monitoring is necessary to ensure proper remediation of the area and is useful in coordination with active remedial methods such as SVE and excavation.例行监测是必要的，以确保该地区的适当的补救措施，并配合积极的补救方法，如SVE和挖掘有用的。
