Abstract

With the development of urbanization, the odor from municipal wastewater treatment plants has disturbed the neighborhood and the control of odor has become an urgency research subject. The H2S odor was treated by the biofilter. The removal load of the biofilter, end products of H2S degradation, and operation process were studied in this paper. The results of removal H2S odor with the biofilter were as follows: When the gas flow rate was 1000m3/h (resident time 16.2s) and 1250m3/h (resident time 13.0s), and the inlet concentration of H2S ranged from 1.876 to 34.705mg/m3, the removal rate maintained above 99.92%, and the average outlet concentration was 0.001 mg/m3 which was far lower than the national level of discharge standard. The relationship between removal rate and temperature satisfied with the formula , and for H2S, θ=1.016. Furthermore, the end products of H2S degradation were only sulfate without sulfide. With the increase of sulfate, the removal of H2S was not affected. The study of operating parameters with the biofilter provided the necessary technical support for industrial design and operation control.
