改性油页岩灰渣处理近岸高盐度重金属废水的性能研究

Study on the Performance of Modified Oil Shale Ash in the Treatment of Heavy Metal Wastewater with High Salinity Near Shore

高盐废水中若含有重金属元素,含盐重金属废水中成分复杂,重金属离子会与其发生反应,生成各种复杂的化合物,使废水中毒性成倍增加。作为一种重要的补充资源,油页岩的储量巨大且其开采量也巨大,产生的油页岩灰渣作为一种工业危险固体废物,因其疏松多孔和孔隙率高的特性,使其具有重要的利用价值。本文以吉林桦甸油页岩发电厂产生的油页岩灰渣作为主要原料,对其进行酸碱改性,得到酸或碱改性油页岩灰渣吸附剂,并研究了其吸附高盐度废水中Pb^(2+)重金属离子的性能。

When the high-salt wastewater contains heavy metal elements,the complex components in the salt-containing heavy metal wastewater are mutagenic,causing heavy metal ions to react with it,resulting in a variety of complex pollutants,the toxicity is doubled,and the higher the salinity,the higher The more difficult it is to treat salt and heavy metal wastewater.As an important supplementary resource,oil shale has huge reserves and its mining volume is also huge.As a kind of industrial hazardous solid waste,the oil shale ash produced has important utilization value,and the oil shale ash produced is important due to its loose,porous and high porosity characteristics.In this paper,the oil shale ash produced by the Huadian oil shale power plant in Jilin Province was used as the main raw material,and the acid-base modified oil shale ash was modified to obtain the acid or alkali modified oil shale ash adsorbent,and its adsorption of high salt was studied.The performance of Pb^(2+)heavy metal ions in waste water.
