摘    要:采用油泥、菌剂及其他添加物充分混合后堆放的方法,进行了3种条件下的微生物对含油污泥的强化分解研究。结果表明,在菌剂和锯末的共同作用下,经过45d后,污泥含油量从24%下降到11%,去除率达到54%;而菌剂单独作用下,含油量下降到16%,去除率达为33%;在没有菌剂作用下,含油量仍然保持在20%以上。对处理过程中pH变化特性进行了研究。试验说明,生物强化分解是含油污泥处理的有效途径。

关 键 词:生物强化处理  含油污泥  微生物菌剂

Abstract:During oil production and process, significant quantities of oily sludge are produced. It has been reported that the bio-augmentation treatment experiments were carried out with microbial preparations under three different conditions in the present investigation. The test was made with maintenance of watering repeated daily. With an aid of nutrient solution and sawdust, we have found that the microbial preparation reduced oil contents in the sludge from 24%to 11%with a removal rate of 54%. In contrast, the oil contents decreased to16%with a removal rate of 33%in the absence of sawdust. It may be concluded that the sawdust pose double effects on the microbial preparation. The sawdust may either improve water content in the system or be regarded as the co-substrate for the co-metabolic activity. However, the oil contents in the control just fell to 20%. In comparison with the control, the microbial preparation was proved to play a major role in the bio-augmentation treatments. During the period of the experiment, a fluctuation of pH values in the oily sludge was also monitored and analyzed. From change of pH values, the status of bioremediation may easily be estimated. The feasibility of the bio-augmentation treatment for the oily sludge was identified.
Keywords:bio-augmentation treatment  oily sludge  microbial preparation
