This paper deals with microbiological and chemical analysis of waste mud, produced in wastewater purification plants of the oil refinery. After digest, mud is removed to the filter press. Compressed mud is placed and stored on the storage yard. Content of organic, anorganic and oil matters and also heavy metals contents were determined. Microbiological analysis comprised determination of total count of aerobic organotrophic organisms and many physiological groups of bacteria. As the indicator of the general biochemical activity, enzymatic (dehydrogenase and phosphatase) activities were determined. Waste mud was mixed with soil (chernozem) in 20%, 40% and 60% amount relations. Changes of activities and quantitative fluctuations of the present microflora were observed after 15 and 30 days. Gained results should enable assessing of using-ability of waste mud in soil-quality improvement, in the sense of its utilization as the fertilizer.
