Embodiment Construction
[0028] The acidic CMC condensate treatment process of the present invention first adopts UBF reactor anaerobic treatment, and then utilizes BAF aerobic treatment, and its process flow chart is as attached figure 1 shown. After the acidic CMC condensate enters the adjustment sedimentation tank 1 for homogenization and precipitation, it flows into the neutralization tank 2 by gravity, and industrial Na with a mass fraction of 15% is added to the tank. 2 CO 3 Alkaline solution, so that the pH value of the wastewater in the neutralization pool is stable between 6.5-7.5, and at the same time, a 10% agricultural compound fertilizer solution by mass is added dropwise. The wastewater stirred by the electric submersible mixer at the bottom of the neutralization tank is injected into the bottom of the UBF reactor 4 by the corrosion-resistant chemical pump 3, and the wastewater is anaerobically purified by the biofilm on the carrier in the reactor and flows into the BAF reactor 5 at the...
