Project case of taurine production wastewater treatment
With the wastewater treatment project of a taurine production enterprise in Hubei as a case study, this paper analyzed the production process and wastewater quality characteristics of the enterprise, the targeted treatment process of “hydrolysis acidification+pre anoxic+aerobic biochemistry+post anoxic+secondary sedimentation” was adopted. When the average influent COD, ammonia nitrogen, and total nitrogen were 956.8, 50.6, 99.1 mg/L, respectively, the average effluent COD, ammonia nitrogen, and TN were 73.6, 1.6, 12.2 mg/L, respectively, with the average removal rates could reach 92.3%, 96.9%, and 87.7%, respectively. The effluent water quality was stable and meet the limits of water pollutants for newly built enterprises in the Chemical Synthesis Pharmaceutical Industry Water Pollutant Discharge Standard(GB 21904-2008). By adopting tapered aeration and fan frequency conversion control, energy consumption was significantly reduced, and the operating cost was 1.60 CNY/m3.
