The invention mainly belongs to the technical field of
pollution treatment of trace
malachite green in a freshwater culture
water body and in particular relates to a performance regeneration and
recovery method of a porous adsorption material adsorbed with
malachite green. The performance regeneration and
recovery method comprises the following steps: collecting the porous adsorption material adsorbed and loaded with the
malachite green to prepare a suspension solution; adding a
reducing agent into the suspension solution in a
solid form or a high-concentration solution form until the
malachite green loaded on the porous adsorption material cannot be detected in a sampling and analysis process; then continually adding a certain amount of the
reducing agent; after continually stirring for acertain time, filtering and removing
surface water to obtain the regenerated porous adsorption material with recovered adsorption performance. According to the method provided by the invention, dyestuffs including the
malachite green and the like, biologically adsorbed, adsorbed by
active carbon, adsorbed by an inorganic mineral porous material and adsorbed by
ion exchange resin, in the
water body can be easily desorbed, so that the
recovery and regeneration of performance of the porous adsorption material made of various materials are realized and the regenerated porous adsorption material is used for the next turn of adsorption and purification process.
