| Aiming at the complexily and poor biochemical degradability of petrochemical wastewater, the effect of toumaoline on bio-contactoxidation method was investigated. The itfluent and effluent of petrochemical wastewater were analyzed by GC-MS, and the carrier wasobserved in reactor by scanning electron microscope(SEN).As the loading rates of influent were COD 0.64-0.72 kg/(m3·d)and NH4+-N0.058-0.072 kg/(m3·d)，the start up of pilot system supported tourmaline were improved，and the removal rate of COD and NH4+-N of
effluent was increased 8.7％ and 6.4％，respectively Organic pollutants of 100 kinds were detected in influent，mainly including aromatichydrocarbon,acids,lipids,phenols,alcohols,and alkanes compounds. The removal efficiency of organic pollutant of reactor 1 withtoumaline was higher than reactor 2 without toumaoline The number of organic pollutant in effluent from reactor 1 and 2 were 14 and 28,
respectively Zoogloea can be observed on carrier supported toumaline,and the biomass of bacteria was predominant. The efficiency of bio-contact oxidation method on petrochemical wastewater treatment can be enhanced by tourmaline |
