Abstract

The invention provides a reduction treatment device for epoxy resin wastewater evaporative desalination mother liquor. The treatment device is composed of a pretreatment device, a high-salinity yeast treatment device and a high-salinity biochemical treatment device. The invention further discloses a treatment device. The epoxy resin wastewater evaporative desalination mother liquor is firstly subjected to pH, water quality and water amount adjustment through the pretreatment device, and the biochemistry of the mother liquor is improved; then high-concentration organic matter is subjected to efficient biodegradation through the yeast treatment device; then the organic matter is further degraded through the high-salinity biochemical treatment device. By means of the device and method, the COD reduction rate of the epoxy resin wastewater evaporative desalination mother liquor can reach 90% or above, and the treated mother liquor can be subjected to evaporative crystallization desalination again, so that the epoxy resin wastewater evaporative desalination mother liquor is greatly reduced, and a large amount of treatment and disposal cost of the desalination mother liquor is reduced for enterprises.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to a reduction treatment device and method for epoxy resin wastewater evaporation desalination mother liquor. Background technique [0002] Epoxy resin wastewater evaporative desalination mother liquor is a high-salt and high-concentration waste liquid produced during the evaporative desalination process of epoxy resin wastewater. Its COD exceeds 100,000 mg / L and its salt concentration exceeds 200,000 mg / L. The main pollutants include chlorine sodium chloride, epichlorohydrin, phenols, toluene, resin particles, glycerin and its polymers, etc. Epoxy resin wastewater evaporative desalination mother liquor is the concentrated liquid produced by the continuous circulation and accumulation of epoxy resin wastewater evaporative desalination process. It has high viscosity and high chroma, and is a dangerous waste liquid. Its disposal cost is 2000~8000 yu...
