Aiming at the complexity and poor biochemical degradability of petrochemical wastewater, the effect of tourmaline on bio-contact oxidation method was investigated. The influent and effluent of petrochemical wastewater were analyzed by GC-MS, and the carrier was observed in reactor by scanning electron microscope (SEM). As the loading rates of influent were COD 0.64-0.72 kg/(m3 x d) and NH4(+) -N 0.058-0.072 kg/(m3 x 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 aromatic hydrocarbon, acids, lipids, phenols, alcohols, and alkanes compounds. The removal efficiency of organic pollutant of reactor 1 with tourmaline was higher than reactor 2 without tourmaline. The number of organic pollutant in effluent from reactor 1 and 2 were 14 and 28, respectively. Zoogloea can be observed on carrier supported tourmaline, and the biomass of bacteria was predominant. The efficiency of bio-contact oxidation method on petrochemical wastewater treatment can be enhanced by tourmaline.
针对石化废水的复杂性和生化降解性差的问题，研究了电气石对生物接触氧化法的影响。采用气相色谱 - 质谱联用仪（GC-MS）分析石化废水的进水和出水，并通过扫描电子显微镜（SEM）观察反应器中的载体。当进水负荷为化学需氧量（COD）0.64 - 0.72 kg/(m³·d)和氨氮（NH₄⁺-N）0.058 - 0.072 kg/(m³·d)时，负载电气石的中试系统启动得到改善，出水的COD和NH₄⁺-N去除率分别提高了8.7%和6.4%。进水检测出100种有机污染物，主要包括芳烃、酸、脂类、酚类、醇类和烷烃类化合物。装有电气石的1号反应器对有机污染物的去除效率高于未装电气石的2号反应器。1号和2号反应器出水的有机污染物数量分别为14种和28种。在负载电气石的载体上可观察到菌胶团，且细菌生物量占主导。电气石可提高生物接触氧化法处理石化废水的效率。
