Využití pokročilých technologií při návrhu smaltované čistírny odpadních vod

Abstract

This master thesis deals with the design of a wastewater treatment plant treating wastewaters of 2000 equivalent inhabitants incorporating new technologies into the cleansing process. These technologies make a possibility to discharge high-quality cleaned water exiting the treatment plants. At the same time, the mentioned modern technologies enable processing of sewage sludge to a quality of first category which can be used as an additive to fertilizers without any further treatment. Theoretical part of the thesis aims to summarize standard processes used in wastewater treatment practice and to present some selected new technologies of tertiary purification and sludge processing. The design of the new wastewater treatment plant is based on the theoretical part of this work. The practical result of this work is a basic design of the treatment plant, consisting of mechanical pre-treatment and biological reactors with settling tanks and their calculations, including a basic design of the proposed WWTP, a list of machines and equipment and an economic evaluation of the project.
