铊污染区土壤与加铊土壤分别用不同量的水冲洗及浸泡,以观察水对含铊土壤的净化状况.结果表明,污染区土壤经浸泡后净化率>多次冲洗组>一次冲洗组。加铊土壤各组净化率也为浸泡组>多次冲洗组>一次冲洗组。而加铊土壤净化率>污染区土镶。雨水对铊污染区土壤有一定的自然净化作用。
Thallium contaminated soil and thallium soil were rinsed with different amounts of water and soaked in order to observe the water purification of Thallium-containing soil conditions. The results showed that after soaking, the soils in the contaminated area had a rate of> multiple flushing> one flushing. Plus thallium soil purification rate of each group is also immersion group> multiple irrigation group> one irrigation group. And thallium soil purification rate> contaminated soil setting. Rainwater has certain natural purification effect on the soil contaminated by thallium.
