Abstract: In order to check the removal efficiency of odour containing Hydrogen Sulphide (H₂S) from Sequencing Batch Reactor (SBR) process at lower temperature, deodorisation experiment was carried out for four months at pharmaceutical wastewater treatment plant in winter by the bio-trickling filter packed with ZX01 stuffing. The results suggested that the removal efficiency of H₂S was higher than 98% and the corresponding volumetric loading achieved 180 g m⁻³ h⁻¹, and the optimum spray water flow rate was 9.5 L h⁻¹. The bio-trickling filter can be operated steadily for a long time at lower temperature.

Keywords: bio-trickling filters; hydrogen sulphide; H2S; carrier; deodorisation; pharmaceutical factory; sequencing batch reactors; SBR; wastewater treatment; odour removal; pharmaceutical wastewater.
