Embodiment Construction
[0021] The following are specific examples of the present invention to further describe the technical solutions of the present invention, but the present invention is not limited to these examples.
[0022] A factory produces multivitamins. After purification and concentration, waste water is produced. The total phosphorus of this waste water exceeds 20000mg / L, COD50000mg / L, and sodium chloride 18%.
[0023] The waste water is pre-oxidized to oxidize and degrade the refractory organic matter into small molecular organic matter, and some of them are directly oxidized into CO 2 , water, which is convenient for salt extraction; the catalytic wet oxidation reaction temperature is set at 160°C, the reaction pressure is 6.0Mpa, and the air supply rate (Nm 3 / h) / Wastewater volume (m 3 / h) 100 times.
[0024] Crystallization is carried out by freezing and crystallization technology, and qualified industrial phosphate is obtained after filtration and cleaning. The total phosphorus f...
