本论文以山东东营某化工厂长期堆积的重污染含油污泥为研究对象，以外源微生物制剂和以麸皮、谷糠为代表的生物有机质为添加物，基于G-model追踪不同添加物对含油污泥中总石油烃(TPH)的降解率及降解速率的影响，考察不同添加物处理条件下含油污泥TPH的去除效果。结果表明：不含添加物的对照组含油污泥经过20 d处理后其TPH的降解率仅为3.98%,而添加外源微生物制剂、谷糠或麸皮后，降解率最高分别可达23.36%、28.64%和34.75%。外源微生物制剂协同生物有机质处理含油污泥，TPH的去除效果显著优于单独添加。麸皮与外源微生物制剂协同处理含油污泥能够达到TPH的最佳降解率41.05%。实现对含油污泥TPH最佳降解率的条件为含油污泥与麸皮的质量比为1∶0.5,外源微生物制剂添加比例为0.5%。在此条件下，TPH的平均降解速率kav为0.26 d-1,是对照组kav(0.000 85 d-1)的306倍。TPH降解率较高的处理体系，其降解速率也较快。添加外源微生物制剂和生物有机质是加快去除含油污泥TPH的有效措施，但需要确定不同外源物质的最适当添加比例才能获得最佳处理效果；而要提高含油污泥TPH的降解率，需要不断改变含油污泥所处的外部环境和处理方式。
Abstract：In this paper, a long time compacted, heavily polluted oily sludge sample from a chemical plant in Dongying, Shandong Province was chosen as the research object, and exogenous microbial agent and biological organic matter represented by chaff and bran were used as additives. Based on the G-model, the effect of different additives on the degradation efficiency and degradation rate constants of total petroleum hydrocarbon(TPH) in the oily sludge were tracked, and the effect of the additives on the removal efficiency of TPH in the oily sludge under different treatments was investigated. The results showed that the degradation efficiency of TPH in the control group without additives was only 3.98% after 20 d incubation, while the highest degradation efficiency reached 23.36%, 28.64% and 34.75% after adding exogenous microbial agent, chaff, or bran, respectively. The removal effect of TPH under the synergism of exogenous agent and biological organic matter was much better than that by separated addition. The best degradation efficiency of TPH in the oily sludge was 41.05% with synergies of bran and exogenous microorganisms. The optimal degradation efficiency of TPH in the oily sludge was achieved when the mass ratio of the oily sludge to bran was 1∶0.5, and the proportion of exogenous microorganisms was 0.5%. Under this condition, the average degradation rate constants of TPH was 0.26 d-1, which was 306 times that of the control kav(0.000 85 d-1). The treatment system with higher TPH degradation efficiencies had higher degradation rate constants. The addition of exogenous microbial agents and biological organic matter is an effective measure to accelerate the removal of TPH in the oily sludge, but it is necessary to determine the optimal proportion of different exogenous substances to obtain the best treatment effect. In order to improve the degradation efficiency of TPH in oily sludge, it is necessary to keep changing the external environment the oily sludge located and the treatment methods.
