Study on the Treatment Technology of the Wastewater from DSD Acid Production

Ferrum carbon aeration catalyticoxidation neutralization flocculation and sedimentation process is used for the treatment of DSD acid wastewater.The results of the treatment show that,through treatment the biotreatabllity of wastewater is improved obviously,and at the same time,the removal efficiency of colourity and COD can reach 98% and 90% respectively.The organic concentration in effluent is reduced,which creates good condition for the following biological treatment.The results of wastewater through ferrum carbon aeration treatment demonstrate agreat increase of pH value and decrease of the dosage of acid and FeSO 4,and the operation cost.
