Biological treatment expertise of sewage water rising from production od DPG (diphenylguanidine).
VEPŘEKOVÁ, Tereza
The main goal of this thesis is to expertise biological treatment of sewage water rising from production of DPG (diphenylguanidine). The theoretical part is focused on the water and means of sewage disposal. There is shortly described mechanism of physical, chemical, biological and combinated methods of sewage disposal. In practical part of this thesis, focused on expertising degradation of DPG and aniline was chosen high performance liquid chromatography (HPLC) technique, which made it possible to determined their biodegradation abilities. The next component of this thesis are sideline products determination, phenylurea especially. This thesis is focused on monitoring of biofilm´s character and the activity of Rhodococcus erythropolis bacterial culture, used in biodegradation of DPG in chemical-biological wastewater treatment plant, LZD a.s.

Analysis of Public Services at the Municipal Level
Rousek, Pavel ; Ochrana, František (advisor) ; Pavel, Jan (referee) ; Šelešovský, Jan (referee) ; Nemec, Juraj (referee)
There are analyzed in this dissertation thesis the public services delivered on the municipal level. This issue is analyzed comprehensive at first. There are analyzed six services in detail after then. These are the six following services: waste, cemetery, greenery, communications, lighting and sewage. The text of this thesis is divided into two major units. The first chapter describes the theoretical background of the problem and the methodology for elaboration. The second chapter analyzes the problem of public services in terms of theoretical con-cepts, legal terms and authors own investigation. This chapter analyzes in detail six selected public services. It is completed draft measures for the municipal public ser-vices. The aim of this dissertation thesis is to find out the State-of-Art of public service deli-vering and to purpose possible changes leading to demand approach of municipal service delivering.

The efficiency of the anionactive surfactants degradation in a constructed wetland vegetation bed.
HAVELKA, Michal
This bachelor thesis is focused on the validation of the anionactive surfactants spectrophotometric determination method. Data from the seasonal monitoring of the anionactive surfactants in a constructed wetland for wastewater treatment with a horizontal subsurface flow were used for the anionactive surfactants degradation efficiency determination and for the determination of the relationship of the wastewater inflow, the constructed wetland´s water temperature, and the constructed wetland´s water redox potential to the degradation efficiency. The spectrophotometric method of the anionactive surfactants determination with methylene blue was used during the study.
