A full-scale integrated-bioreactor with two zones treating odours from sludge thickening tank and dewatering

Jianwei Liu, Kaixiong Yang, Lin Li, Jingying Zhang

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 4, doi: 10.1007/s11783-017-0932-8

Abstract: A full-scale integrated-bioreactor consisting of a suspended zone and an immobilized zone was employed to treat the ordours emitted from a wastewater treatment plant. The inlet concentrations of H S and NH were 1.6–38.6 mg·m and 0.1–6.7 mg·m , respectively, while the steady-state outlet concentrations were reduced to 0–2.8 mg·m for H S and 0–0.5 mg·m for NH . Both H S and NH were eliminated effectively by the integrated bioreactor. The removal efficiencies of H S and NH differed between the two zones. Four species of microorganisms related to the degradation of H S and NH were isolated. The characteristics and distributions of the microbes in the bioreactor depended on the inlet concentration of substrates and the micro-environmental conditions in the individual zones. Product analysis indicated that most of the H S was oxidized into sulfate in the immobilized zone but was dissolved into the liquid phase in the suspended zone. A large amount of NH was converted into nitrate and nitrite by nitration in the suspended zone, whereas only a small amount of NH was transferred to the aqueous phase mainly by absorption or chemical neutralization in the immobilized zone. Different microbial populations dominated the individual zones, and the major biodegradation products varied accordingly.
