金属钨酸盐在有机废水处理中的应用进展

Progress on metal tungstate applied in organic wastewater treatment

金属钨酸盐由于比表面积大、孔隙率高、粒径小,具有很强的吸附能力,在光照、超声等外界作用下,能够产生大量活性物质,从而有效去除废水中的有机污染物。综述了金属钨酸盐借助吸附及声、光催化等方法处理有机废水的效果,探讨了影响处理效果的因素,提出了可能的机理,并展望了金属钨酸盐处理有机废水的前景。

Metal tungstates have strong adsorption capacity due to its large specific surface area, high porosity and small particle size.Under external effects, such as light and ultrasound, the material can produce a large amount of active substances, which can remove effectively organic pollutants in wastewater.The effects of metal tungstates on the treatment of organic wastewater by means of adsorption, sonocatalysis and photocatalysis were reviewed.In addition, the influencing factors of treatment process were discussed, and proposed their possible mechanisms.Finally, the application of metal tungstate on the treatment of organic wastewater was prospected.
