Zero-discharge treatment method and device for PVA fiber production wastewater

The invention relates to a PVA fiber production wastewater treatment method and device. The wastewater enters a multi-medium filter after being homogenized to adjust the pH, so that the content of suspended solids in the wastewater is reduced. And the content of suspended matters and colloids in multi-medium produced water is reduced by adopting an ultrafiltration system. Ultrafiltration produced water enters a first reverse osmosis membrane to be concentrated, first reverse osmosis membrane concentrated water is subjected to hardness removal through a hardness removal filter, and produced water of the hardness removal filter is further concentrated through a second reverse osmosis membrane system. After second reverse osmosis membrane concentrated water passes through an ion concentration allocation system, crystallization treatment is conducted on the concentrated water, most crystallization mother liquor flows back to the ion concentration allocation system, ion concentration allocation produced water is further concentrated through a third reverse osmosis membrane, and power plant ash spraying treatment is conducted on third reverse osmosis membrane concentrated water; and the produced water of the three reverse osmosis units is recycled after COD is further reduced through advanced oxidation.
