不同吸附材料去除土壤淋洗液中砷的效果研究

, 2013
原位淋洗技术是土壤砷污染修复领域的热点,但含砷淋洗液的处理仍然是一个难题。试验研究了铁粉、氧化铁、活性炭、膨润土及其混合物共8种材料对含砷淋洗液中砷的吸附效果和吸水特性,以期筛选出最佳除砷材料。结果表明:氧化铁和氧化铁+活性炭(1:1)两种材料对砷的去除效果最好,去除率达100%;氧化铁+活性炭(1∶2)、活性炭、膨润土+活性炭(1∶1)、铁粉等4种材料去除砷也有较好效果,去除率分别为78.9%、73.3%、36.5%、27.2%;膨润土、铁粉+膨润土两种材料对淋洗液中的砷无去除效果。综合考虑认为 ...

我国燃煤电厂砷的大气排放量初步估算

, 2004
研究了不同燃烧条件下我国燃煤电厂砷的大气排放量,采集和分析了高温和中、低温燃煤电厂的原煤、底灰、飞灰的砷含量,对我国每年动力煤砷的排放量和排放率进行了初步分析和估算.结果表明:高温燃煤电厂燃烧1t含砷5mg/kg左右的烟煤,排放到大气中的砷为0.40g左右,其排放率为7.70%左右;中、低温燃煤电厂燃烧1t含砷5mg/kg左右的烟煤,排放到大气中的砷为0.15g左右,其排放率为2.79%左右.中国火电厂动力用煤每年约6×108t左右,主要为华北区和西北区的石炭~二叠纪的动力煤,以含砷量为5mg ...
