Example Embodiment
[0058] Example 1
[0059] A coal-based glycol wastewater treatment method includes the following steps:
[0060] Subjecting the coal-to-ethylene glycol wastewater to a stripping purification treatment, recovering organic matter in the stripping gas, to obtain first-level treated wastewater;
[0061] Performing anaerobic biological treatment on the wastewater of the primary treatment to obtain wastewater of the secondary treatment;
[0062] Performing aerobic biological treatment on the wastewater of the secondary treatment to obtain wastewater of the tertiary treatment;
[0063] Fenton oxidation treatment is performed on the tertiary treatment wastewater to obtain fourth-level wastewater;
[0064] Performing the biological aerated filter treatment on the fourth-stage treated wastewater to obtain the fifth-stage treated wastewater;
[0065] Ultrafiltration and reverse osmosis are sequentially performed on the five-stage treated wastewater to realize reuse after discharge.
