Sažetak
The rapid population growth in recent decades, leads to an increase in living standards. Continuousdevelopment of society causes large and adverse changes in the environment. Awakening awareness of the importance of sustainable development, results in the emergence of new branches of engineering aimed at the development of new and improvement of existing technologies with respect to the closed production cycle. Construction of plants for biological treatment of wastewater results in increase in amount of sludge. The purpose of sludge treatment is to decrease its amount and the cost of storage. By anaerobic digestion the sludge is stabilized and biogas, a renewable source of energy, is produced. Co-digestion is an anaerobic digestion at least two types of substrates in order to increase process efficiency, to yield methane as high as possible. This paper characterizes the sludge which is obtained in the process of aerobic treatment of industrial wastewater. Based on the results of the BMP tests, the cosubstrate has been chosen as well as the ratio I/(S+KS) for the process of anaerobic digestion. In the experiments the volume of biogas was measured, volume ratio of methane, carbon dioxide and nitrogen was determined, and physico-chemical and microbiological analyses were carried out. The most efficient process was carried out with the cosubstrate cardboard and the ratio I1/(S+K) = 1.0.
