Abstract
The invention discloses a kind of methods of resin adsorption desorption diffusion dialysis processing VA races element oxo-anions waste water, belong to wastewater treatment and recycling reuse field, specifically, it is related to a kind of method of resource of resin adsorption desorption and diffusion dialysis combination to phosphorous acid group, orthophosphite, arsenate, arsenous anion and metaantimmonic acid root waste water.The method includes with resin adsorption VA races element oxo-anions waste water, then regenerating resin desorption with aqueous slkali, VA race's element oxo-anions and lye then are detached with diffusive dialysis method, wherein recycle of alkali liquor set is for desorption and regeneration step.In the method for the present invention, in addition to detaching VA races element oxo-anions and being enriched with, lye can recovery again, last discharge Shui Zhong VA races element oxo-anions concentration is down to below 0.01mg/L, significantly reduce production cost and environmental pollution, meet the energy-saving and emission-reduction industrial policy of current country, suitable for industrialization promotion.
