Abstract

The invention discloses a treatment technology of decolorized resin regenerated waste liquid. The treatment technology comprises the following steps: after filtering the decolorized resin regeneratedwaste liquid through a filter, filtering through a nano-filtration membrane; recycling permeated liquid; adding lime milk into obtain intercepted liquid; introducing flue gas and fully filling; aftercarrying out plate and frame filtering on a fully-filled mixing system, recycling permeated liquid and repeating the operation on intercepted liquid. Compared with the prior art, pigments in resin regenerated waste liquid can be effectively removed; the recycling rate of resin regenerated liquid is high and the production cost is low; the treatment technology is simple to operate and has the advantages of high efficiency, energy saving and emission reduction.

Description

technical field

[0001] The invention belongs to the field of chemistry, and in particular relates to a treatment process for decolorized resin regeneration waste liquid. Background technique

[0002] Ion exchange resins can be widely used in water treatment, food industry, pharmaceutical industry, synthetic chemistry and petrochemical industry, environmental protection industry, hydrometallurgy industry, etc., mainly used for desalination, decolorization, product purification, etc. The decolorizing resin is mainly used for the efficient removal of polyphenol pigments, caramel pigments, natural pigments, etc. in the food industry. It has a wide range of decolorization, high decolorization capacity, can remove various ions, can be regenerated repeatedly, has a long working life and low operating costs. The reusability of ion exchange resins is one of the main advantages of ion exchange resins being widely used in industrial production

[0003] After the ion exchange resin ha...
