Abstract
The present invention discloses a method for treating wastewater produced in 4 B acid production and recovering resources. Wastewater in 4 B acid production is filtered after proper regulation of the pH value, and the filtered water passes through an adsorption tower filled with macroporous resin at the temperature of 10 to 50 DEG C. at the flow rate of 0.5 to 4 BV/h. Dilute ammonia water and water are used as a desorbing agent for desorbing and regenerating the macroporous resin which absorbs organic substances. The desorbed high-concentration eluting liquid is stripped by air, and water is used as absorbent for recovering the ammonia water. After the wastewater is concentrated to a half of the original volume through vacuum distillation, the pH value is adjusted to 0 to 3 by sulfuric acid, and the coarse 4 B acid is recovered after filtration. Low-concentration eluting liquid is used for the next batch of desorbing operation. By the method, CODcr of 4 B acid production wastewater after resin treatment is reduced to less than 300 mg/L from 8000 to 10000 mg/L, and the removal rate of CODcr is more than 96%. Wastewater can reach the discharging standard through biochemical treatment, and the recovery rate of 4 B acid is more than 55%. Thereby, the present invention realizes the effective treatment of wastewater and the reutilization of resources and has obvious environmental benefits, economical benefits and social benefits.
