Pretreatment Hydrolysis Acidification/Two-Stage AO Combination Process to Treat High-Concentration Resin Production Wastewater
نویسندگان
چکیده
The rapid development of the resin industry has led to a large amount high-concentration production wastewater, which created serious water pollution problems while limiting related enterprises. In this study, combined pretreatment hydrolysis acidification/two-stage anaerobic oxic (AO) process for wastewater was constructed, and effect operation time on treatment efficiency acidification two-stage AO unit investigated using chemical oxygen demand (COD), total nitrogen (TN), NH3-H (ammonia nitrogen) as indicators. investigated. Results showed that “alkaline digestion + ozone oxidation” could effectively remove volatile phenols phenolic organic pollutants from wastewater. average removal rates COD, TN, were 91.96%, 85.35%, 85.67%, respectively. concentrations final biochemical effluent 404.7, 21.4, 11.4 mg/L,

Two-stage anaerobic process treating high concentration methanol wastewater and
In our study, two-stage anaerobic system was employed to treat high concentration methanol wastewater. The results showed the COD removal efficiency was over 90% at the volume loading of 26.8kgCOD/(m.d) and two-stage anaerobic digestion of methanol wastewater was more efficient and stabler than one stage. The pH of the two UASBs was always lower than 6.0, which wasn’t the suitable condition tha...
