含钼废水的处理技术与机理

Analysis of the treatment technology and mechanism of molybdenum-containing wastewater

钼是微生物、植物和动物体内必需的微量元素,但过量摄取会导致不良后果,且不同程度的钼污染事件屡屡暴发。介绍了当前国内外含钼废水处理的若干技术,包括吸附法、化学沉淀法、离子交换树脂法和溶剂萃取法的去除效果、机理及影响因素等,总结了处理技术的优点与缺点,并展望了含钼废水处理材料未来的研究方向。

Molybdenum is an essential trace element in microorganisms,plants and animals,but it will produce adverse effects when excessive intaked,and the molybdenum contamination of different level have soccurred.The removal effects,mechanisms and influence factors of some technologies,including adsorption,chemical precipitation,ion exchange resin and solvent extraction for molybdenum-containing wastewater treatment was reviewed.The advantages and disadvantages of these treatment technologies were summarized,and the research direction of molybdenum-containing wastewater treatment materials was prospected.
