An approach to purification of CS2 waste-gas in low concentration using biological trickling filter

The paper studied an approach to purification of CS₂ waste gas in low concentration using biological trickling filter. The results of preliminary experiment showed that, when the gas flow was 100-500mg/m³, the CS₂ removal efficiency arrives percent 70-78% by using trickling filter, But the biological elimination of CS₂ in waste gas could be increased from 2.06mg/(L h) to 22.52mg/(L h); meanwhile the gas flow was increased, the CS₂ removal efficiency was declined from 74.5% to 37.1% The kinetic model of adsorption-biofilm theory had a good applicability for describing process of CS₂ waste gas. The interrelation coefficient between experimental points and calculated points was very well.
