Vliv technologie kompostování biologicky rozložitelných odpadů na kvalitu kompostu
DVOŘÁK, Zdeněk
The thesis deals with composting and ways of handling biodegradable waste and biodegradable municipal waste. It explains the terms related to composting and processing of BW and BMW and clarifies the difference between humus and primary organic matter and its composition. Furthermore, the thesis covers qualitative and quantitative features of compost, raw material composition of the dump, and factors influencing the process of decomposition itself. The practical part of the thesis describes the quality of the compost from the municipal composting plant Písek. This part also includes a description of the composting plant and a description of the composting process. The main part and the goal of the thesis is to determine the ion-exchange capacity T according to Sandhoff and to suggest the optimal composting technology in the Municipal composting plant Písek.

Analýza půdní organické hmoty v kambizemi modální po šesti letech každoročního hnojení zemědělským a komunálním kompostem
BROUČKOVÁ, Vlasta
Organically overfertilization cambisoil modal after conversion to kultizem horticka was further fertilized in version P compost industry (communal) and version H compost humus (agricultural) containing 13,72% of humus and 22,78% of the primary organic matter over a period of 6 years dose 50 t / ha annually. Fertilization with an actual compost H in organically fertilized soil reflected not only by increasing the ion exchange capacity of the soil, but also a significant improvement of water regime of soil, manifested by a quarter greater ability to maintain the water in the soil and 44% lower amount of water, physiologically ineffective.

Quality control of biodegradable waste process
Krbalová, Maria ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The waste production and especially biodegradable waste is following mankind since the beginning of his existence. This thesis deals with a description and dividing of current available waste process technologies, including description of their advantages and disadvantages. The work is also focused on the more detailed description of the composting technology, its control and opportunities to influence on resulting parameters of compost product. The information about technical description of workplace equipments, including industrial and technological processes was provided by the company VIA ALTA from their compost plant in Blansko.

Influence of compost application on properties of soil humic substances
Enev, Vojtěch ; Pospíšilová, Ľubica (referee) ; Klučáková, Martina (advisor)
The aim of this diploma thesis is to study to the influence of compost addition to soil humic substances extracted from blackland luvicsol. Humic substances extracted from soil and from compost were characterized by titration with potentiometrical and conductival indication, UV-VIS, FT-IR and 3D EEM fluorescential spectroscopy. Compost in amount of 124, 239 and 478 t/ha was applicated and manured into dept of 150 mm at blackland luvicsol. The main aim of thesis was the appraisal of compost influence into fluorescent attributes of soil HS and localization of fluorescent peaks at excitation emission spectrums. Next part of diploma thesis was focused on the study of spectroscopic attributes of soil HS and compost by UV-VIS and infrared spectroscopy with Fourier transformation. Humic substances were characterized by humifical index E4/E6 and transmissional vibratile spectrums. The last aim of diploma thesis were the characterization of soil HS extracts and compost by acidimetral titration. For each sample was calculated value of H+ ionts amount of substance from measured titrational curves.

The study of enzyme activities in compost
Pernicová, Iva ; doc.Mgr.Pavlína Pelcová, Ph.D. (referee) ; Voběrková, Stanislava (advisor)
This thesis deals with the determination of enzyme activities in compost for consideration their changes during the composting. The changes in the activity of particular enzymes serve as the indicators of the activity of microorganisms, which are found in the compost. In the practical part of the work the changes in activity of proteases, cellulases, lipases, dehydrogenases and ureases within 21 days of composting under laboratory conditions were determined. The change in pH was observed as well. The changes in the pH-values and all enzyme activities except ureases present in the first week the same trend associated with the use of available substrates. The changes in the activities of the key enzymes in compost under laboratory conditions were compared with the changes in activities in compost under real conditions, which is the indicator of the different composting process under the given circumstances.

Composting of sewage sludge of small producers
Pumprlová Němcová, Miroslava ; Hynánková,, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
This thesis deals with the composting of sewage sludge and wetland plants biomass wasted from treatment wetlands. The introductory part of this thesis is the literature research of technical information from authors who deal with the topic of sewage sludge and composting. The introductory part provides basic information about the issue compost and composting. The theoretical part of this thesis is followed by the practical part. The practical part is divided into two research projects. The first one is focuses on methodology of building compost from waste materials such as sewage sludge and wetland plants biomass. The second one deals with the testing and usability soil moisture sensors mostly used to monitoring of the compost humidity. The research work is focused on soil moisture sensors calibration. The measurement results will be statistically analyzed and used for further work with soil sensors of compost. Results of the work can serve materials for operators and owners of treatment wetlands. This solution would lead to a significant reduction of operating costs when is considered sludge management.

Composting in the Czech Republic
Glombová, Pavla ; Horák, Marek (referee) ; Hluštík, Petr (advisor)
The aim of bachelor thesis is a description of the issue related to biological disposing of degradable waste by composting. It is concerned by the most important valid laws in this field, by technologies of composting and by the facilities used to dispose these waste – by composting facilities. In the practical part there is a compiled database of composting facilities in the Czech Republic, sorted by the regions. Their basic data are included (operator, address, website, contact information, capacity, used technology, amount of compost production, its price and utilization, accepted waste, used machinery and equipment, the year of commissioning, intensification).

Compost accelerator to composters and garden composts
HÁJEK, František
The purpose of this paper is to research and suggest good-quality compost accelerators that could be effectively used in the garden composts. The additive eliminates the shortage of the input pulverized grass matter which is being composted. This thesis also describes the features of the compost, the nature of the correct composting procedures, and the legal implications to the production of the composting process. This paper elaborates the efficiency of the compost accelerators that are available within the home market and abroad. An important component of my accelerator is magnesium from the Dolomites limestone distributed by the "HASIT" company which positively affects the process of humification. The experiment of compostation with this type of accelerator took place on the pulverized grass matter. In order to objectively assess the quality of the composts, the Sanhoff´s method of stating the cation exchange capacity was used. During this experiment, the cation exchange capacity increased by 22% in the sample where the accelerator has been used, as compared to the sample where only the composted grass matter was present. Based on the results gathered, it is feasible to conclude that the suggested accelerator does have a significant impact on the composting of the grass matter. Due to this fact, it is strongly recommended to conduct a further research on the composition of the compost accelerators.
