Metal mine tailings remediation; Geochemical processes occur in plant-microbial-tailing mineral continuum; Volatile sulfur odorants' abatement using biotrickling filter.

Sewer odour problems have been widely reported worldwide for the last decade. Odour emission from sewers not only adversely affects the living environment and human health but also highly corrodes and damages sewerage facilities. Volatile sulfur compounds (VSCs) are the most frequently reported odorous compounds in sewer emissions. However, the removal of VSCs in previous literature was poor and variable. Hao Bu's PhD research investigated the removal performance and processes of VSCs in a biotrickling filter based on lab experiments and mathematical model.


Having obtained a bachelor’s degree in water and wastewater engineering and a master’s degree in Municipal Engineering in China, Hao obtained his PhD in Environmental Engineering (ACWEB, UQ) where he participated in two ARC projects as a casual research assistant, researching sewer corrosion reduction.

Hao is currently a Research Assistant at Centre for Mined Land Rehabilitation, The University of Queensland with a main working responsibility to providing technical support by means of IC, GC, etc for physical/chemical analysis of trace element in soil-water-plant samples from the research about rehabilitating metal mine tailings.  Hao has published 4 research papers about sewer corrosion and odour management.

He is a member of the Australian Water Association.
