什么是污染土壤的处理?
什么是污染土壤的处理?

Contaminated soils can lead to pollution of groundwater and harm animals and plant life.污染的土壤可造成污染地下水和伤害动物和植物的生命。 Severe cases of contaminated soil may even kill organisms which affect the entire food chain because the insects that feed on the organisms may either die from the pollutants or move to less contaminated areas.受污染的土壤严重者甚至会杀死生物体的影响整个食物链,因为昆虫对生物体的饲料可能死亡的污染物,或转移到污染较轻的地区。 This disruption of the food chain can cause entire ecosystems to be adversely affected.这种食物链的破坏,可能会导致整个生态系统会受到不利影响。 Treatment of contaminated soils can help reverse the affects.污染土壤的处理,可以帮助扭转的影响。

  1. Causes原因

    • Soil can be contaminated in several ways.污染的土壤可以在几个方面。 Industrial spills during business operations is the primary reason for severe cases of soil contamination.在业务运营的工业泄漏的首要原因是土壤污染严重的情况下。 This could be caused by leaks from underground storage drums or improper disposal of chemicals.这可能是由地下储存桶泄漏或化学品的处置不当引起的。

      Accidents during the transport of dangerous chemicals can cause the soil to be contaminated.在危险化学品运输事故,可能会导致土壤受到污染。 If companies do not dispose of byproducts from their manufacturing operations properly, it can seep into groundwater and surrounding soils.企业如果不妥善处理其制造业务的副产品,它可以渗入地下水和周围的土壤。

      Municipalities that have old sewers or sewers that require maintenance can inadvertently cause waste to dump into rivers or lakes, then leak into the soil.有需要维修的旧污水渠或污水渠的城市就会在不经意间导致废物倾倒入河流或湖泊,然后泄漏到土壤。

      Farmers and even home gardeners that use an overabundance of pesticides or manure can contaminate the soil.农民甚至家庭园艺使用过多的农药或肥料污染土壤。 Too many pesticides can prevent the soil from being used again without possibly causing health concerns.太多的农药可以防止正在使用的土壤,而可能造成的健康问题。

    Treatments治疗

    • Treatment depends upon the type of contamination and the size of the contaminated area.治疗取决于污染和受污染面积的大小。 If a business has been found to have caused the contamination in the United States, the Environmental Protection Agency (EPA) will govern the clean up.如果一个企业已经发现已在美国造成的污染,环境保护署(EPA)管的清理。

      Excavation is the process of removing the contaminated soil from the ground.开挖清除受污染的泥土从地面的过程。 If the contamination cannot be removed, the soil is taken to a disposal facility and burned.如果无法去除污染,土壤被处置设施,并烧毁。 The burning kills any organisms and pollutants.燃烧杀死任何生物和污染物。 The soil may also be taken to a treatment facility and processed through a carbon adsorption tower.也可采取土壤处理设施,并通过活性炭吸附塔处理。

      Another way to remove soil contamination is through bioremediation.清除土壤污染的另一种方法是通过生物修复。 This involves putting organisms in the soil that like to feed on the contaminant.这涉及到把希望饲料污染物在土壤中的生物体。 They will eat the pollutants and can then be removed.他们会吃的污染物,然后就可以删除。 This works especially well with oil spills because the organisms can clean up the mess quickly and economically.这与漏油,特别是因为微生物可以迅速收拾残局和经济。

      If the area of soil contamination is small, often containment is the best treatment option.如果土壤污染的面积是小的,往往遏制是最好的治疗方案。 This may involve something as simple as putting a plastic tarp over the area to prevent rainwater from getting into the area and spreading the contaminants.这可能涉及到以上的面积,以防止雨水进入该地区和传播的污染物如把一个塑料篷布简单的东西。 It can also require adding additional material to the area to help dilute the contaminants.它也需要增加额外的材料前往该地区,帮助稀??释污染物。 Typically, this option is best suited for soil that will not be used for some time, thus allowing the contaminants to degrade and become harmless.通常情况下,这个选项是最适合对土壤不会被使用一段时间,从而使污染物的降解成为无害。
