Soil washing refers to the use of solvents such as water to wash the contaminated soil so as to separate fine soil from its larger constituents such as gravel and sand. You might find these chapters and articles relevant to this topic. Nanthi S. Bolan, ... Mary B. Kirkham, in Advances in Agronomy, 2013.

2013年1月29日 · Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil …

土壤水洗是用清水对污染土壤进行洗涤，将附着在土壤颗粒表面的有机和无机污染物转移至水溶液中，从而达到洗涤和清洁污染土壤的目的。 土壤淋洗的作用机制在于利用淋洗液或化学助剂与土壤中的污染物结合，并通过淋洗液的解吸、螯合、溶解或固定等化学作用，达到修复污染土壤的目的。 [1] 土壤淋洗修复的实现方式主要分为原位淋洗和异位淋洗，其中异位淋洗又可分为现场修复和离场修复。 原位土壤淋洗修复技术是根据污染物分布的深度，让淋洗液在重力或外力作用下 …

Soil washing is an ex situ process that reduces the volume of contaminated material that must be further treated or disposed. Soil washing systems operate on the principal that most contaminants of concern (COCs) bind to the finer soil fraction, consisting of clays, silts, and fine organic matter as opposed to the larger sand and gravel fraction.

Soil washing is a water-based process for mechanically scrubbing soils ex-situ to remove undesirable contaminants.

Soil washing is a technology that uses liquids (usu-ally water, sometimes combined with chemical addi-tives) and a mechanical process to scrub soils. This scrubbing removes hazardous contaminants and con-centrates them into a smaller volume. Hazardous contaminants tend to bind, chemically or physically, to silt and clay.

2021年2月3日 · Soil washing is widely considered as a common method of soil remediation. This study examined the developments in soil washing during the past 20 years via a bibliometric and systematic critical review.

2017年3月27日 · Soil washing does not clean the soil, it separates the contaminated fraction from the clean fraction, hence minimizing the amount of soil need to be cleaned. Sometimes soil washing alone does not clean the polluted soil enough (therefore other methods must be used after) If there is a high organic content in the soil, it may require pretreatment.

Soil washing is an Environmental friendly remediation technology designed to eliminate soil contaminants effectively. This process typically involves the use of water or other specialized solvents to physically and/or chemically remove or neutralize pollutants.

Rainwash, also spelled rain-wash or rain wash or sometimes called hillwash, is a process of erosion in which loose surface material is carried away by rainwater that has reached the surface, but has not yet become concentrated into streams.
