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.
