Effect of Pyrolysis on the Improvement of Sewage Sludge Properties

Bc. Leidy Marcela Ulloa Murillo

Diplomová práce

Abstract:

Literature review will focus on two main topics. Firstly, effect of sewage sludge application on soil properties, critical factors, limitations and legislation related to sewage sludge application to soil. Secondly, pyrolysis of sewage sludge with special emphasis on behavior of trace elements during pyrolysis, technological solutions and parameters of pyrolytic conditions in relation to final properties of biochar. Chemical processes appearing during high-temperature pyrolysis should be covered by the review as well. Under experimental part of the thesis, two different sewage sludges with distinct properties will be pyrolysed at temperatures 600 – 800 °C and under different rates of temperature-increment during pyrolysis. Focus will be put on evaluation of mentioned pyrolytic conditions on chemical properties of resulting biochars, especially total and bioavailable contents of trace elements.
