Evaluation of VOCs Purification System from Wastewater in a Shijiazhuang Bio-Pharmaceutical Factory

Abstract:

The characteristics and purification effect of wastewater VOCs from a shijiazhuang bio-pharmaceutical factory were studied throμg h summa canister , preconcentration system and meteorological chromatography - mass spectrometry (GC - MS) . The VOCs are classified according to the functional groups, boiling point, molecular weight and carbon number, and its characteristics and treatment process were discussed based on total emissions, kinds, alkaline cleaning efficiency, biological efficiency and total efficiency. The results show that the largest concentrations of VOCs is the sulfur-containing compounds, boiling point of 81 ~ 110 °C and molecular weight of 20 ~ 50, which has better treatment effect, and efficiencies are above 99%.
