UTILIZATION OF SEWAGE SLUDGE
Sewage sludge utilization technologies must meet two requirements: the use of energy potential and ensuring that the products of their processing are not negatively affected by the environment. New technologies for the disposal of sediments that meet these requirements are being developed: pyrolysis, hydro pyrolysis, combined processes of fermentation and gasification, polygeneration, steam conversion, gasification of mixtures with other fuels, thermocatalytic reforming, three-stage gasification. Most of these technologies have not yet been commercialized. The energy potential of «fresh» sediments in Ukraine is estimated at 446 thousand tons of conditional fuel. Its use for the electricity production and thermal energy and secondary liquid and solid fuels is appropriate as being consistent with the global trend of decentralized energy development. The economically efficient, acceptable for Ukrainian conditions is the technology used to dispose of sediment, is their joint combustion with other solid fuels and waste in boilers of power stations and in cement kilns. For objects of decentralized energy, it should be preferred to the processes of gasification or pyrolysis of sewage sludge. Composting technology is acceptable to dispose of accumulated precipitates.
