Learning outcomes
|
Students will become familiar with the problems of the degradation of organic matter from the perspective of environmental protection. In particular, will be discussed the principles of biodegradability of organic substances in aerobic and anaerobic conditions and advanced degradation processes such as chemical oxidation, photolysis, ozonization and photocatalysis and their application in air, water and/or soil treatment technologies. Physico-chemical, biochemical and microbiological principles of purification and operational specifics of individual technologies will be also explained.
Graduates are expected to have an ability to describe common types of environmental pollution by organic substances and subsequently identify, describe and compare methods suitable for the treatment of a given type of air, water and/or soil pollution.
