Abstract
The invention discloses a technology for treating SIPM waste water recovered material, which is characterized by concentrating SIPM waste water, and centrifuging; first heating for dissolving, and crystallizing; first centrifuging; second heating for dissolving, filtering and crystallizing; and drying and packaging. The invention effectively solves SIPM waste water recovered material treatment problem, and increases profit for SIPM production manufacturers.
Description
Technical field
The present invention relates to the recycling of industrial chemicals, particularly a kind of SIPM waste water reclamation material treatment process.
Background technology
Need to carry out thermosol with a large amount of deionized waters in the SIPM production process and make with extra care, generate a large amount of waste water.This SIPM waste water mainly contains SIPM, 5-SSIPA, sodium sulfate and some other impurity, strongly-acid, severe corrosive, and environmental requirement does not allow directly to efflux, and must process.SIPM waste water usually conduct method is heating evaporation, water recycling up to standard in the SIPM production technique, but after the evaporation at the bottom of the still residual strongly-acid reclaimed materials can't process because containing a large amount of impurity, can only accumulation deposit, become SIPM production development technical bottleneck.
Summary of the invention
The present invention proposes a kind of technical scheme, and to address the above problem, the technical program is: the SIPM Waste water concentrating is centrifugal; A thermosol, crystallization; Once centrifugal; The secondary thermosol filters crystallization; Five operations of dry packing.Not only effectively solve SIPM waste water reclamation material and process problem, also can be SIPM manufacturer increases profit, only drops into the not history of output with thoroughly changing the SIPM wastewater treatment.
