Zusammenfassung:The invention relates to an MVR decolorization sustainable production method and an MVR decolorization sustainable production device. The MVR decolorization sustainable production method is characterized by including the steps of a, pumping raw water into a decoloring kettle, adding activated carbon, controlling the mass ratio of the activated carbon to the raw water to be 1 to 75, increasing thetemperature to 65-70 DEG C and performing heat preservation for 2-2.5 hours, feeding the decolorized wastewater into a filter press at the flow rate of 0.6 m/s, and removing organic matters and toxicand harmful substances to obtain high-salt wastewater; b, feeding the high-salt wastewater obtained by filter pressing in the step a into an MVR system at the rate of 0.5-0.6 m/s for decompressed distillation, and controlling the pressure within 0.075-0.08 MPa and the temperature within 70-72 DEG C to obtain a white crystalized salt and wastewater.
