Oil accidents anf theis effect on water quality.
Lebdušková, Helena ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
The basic aim of the thesis is descritpion of oil accidents, which are these days the normal part of our lives. I deal with the issue of oil extraction as a base material for petrol, oil and other oil-based products. The current methods of production make these accidents impossible to avoid. The biggest problems come from using large tankers to transport the oil, other problems bring oil processing and waste production. This thesis focuses on the assessment of oil accidents and their effects on water quality, as well as on the whole ecosystem. Keywords Oil, oil accident, water pollution
Crushes and theirs effect on water quality
Uhrová, Adéla ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
This thesis is focused on accidents in water and their their division into groups according to different factors. Work detailing the chemical accidents resulting in pollution of surface and groundwater, which became the Czech Republic since 2000. Describes chemicals that often escape into the water and damage to their quality. Furthermore, there is described an accident in 2006, when form "Lučební závody Draslovka, Kolín" leaked into the Elbe dangerous cyanide. Key words: Accidents, water pollution
Cleaner production
Stegarescu, Rodica ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
Preventing negative impacts on the environment is better than fixing it afterwards. From this argument the field of cleaner production has developed, which is the continuous application of an integral strategy to processes, products and services to increase the overall efficiency and reduce the risks to humans and the environment. For production processes cleaner production defines more efficient use of raw materials and energy, elimination of toxic, hazardous materials and preventing waste and emissions at source. For products (goods and services) cleaner production strategy focuses on reducing their environmental impact, and across their entire lifecycle, from development to their use. This strategy was firstly implemented in the United States, in the 3M company from Minnesota and after obtaining positive results, it spread all over the Word, in Europe though, pioneers were the Swedes. Many international organizations have created programs for the promotion and development of cleaner production in as many countries as possible, mostly through the National Center for CP, which were established in the early nineties by UNIDO and UNEP. These centers were created to provide services for businesses, governments and other participants and to assist with the implementation of methods, practices,...
Methods of treatment of urban waste water and the possibility of using treated water
Charalambous, Panagiotis ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
Nowadays, wastewater treatment is becoming increasingly necessary due to the reduction of water resources, the increasing price of drinking water, as well as the shrinking underground water reserves. The treatment of wastewater for reuse and disposal is particularly important for countries and regions which suffer from drinking water shortage. Thus, it is vital to find sustainable solutions for the better protection of the environment and also to improve the water's quality by adapting new and more efficient technologies. This bachelor thesis contains a comprehensive study of different methods and technologies that are used today for the wastewater treatment, with a specific emphasis on urban wastewaters. Furthermore, it examines the post-treated wastewater management, including possible ways of reusing them in many aspects. Keywords: urban wastewater, activation process, biofilters
Waste management - SUBTERRA
Pokorná, Alice ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
This bachelor work is focused on the waste management of major company implementing in the field of construction work. The teoretical part is addressed in legislation dealing with issue in the Czech republic and the general issue of construction waste. In the practical section provides specific procedures especially as Subterra followed in practice their program works and on which it is implemented. I've explored waste management in practice, not only by legislation. It can be concluded that the company proceed with the implementation of their projects in accordance with the law.
The study of recycling non-ferrous metals in the EU and the Czech Republic
Rákosník, Vítězslav ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
Overall, recycling entails both advantages and disadvantages. The major advantage is saving large amounts of energy in recycling compared to primary raw material, which is another big plus for recycling non-ferrous metals - save primary raw material. The Czech Republic and many other countries are largely dependent on imports of certain raw materials (aluminum, lead, copper, etc.) or just on mentioned recycling. Nowadays, increase in the number of electrical devices (computers, mobile telephones, tablets, etc.), is recycling of scrap metal very important, because in each device occurs a certain amount of non- ferrous metals, noble metals, which can be used again. In this work will be described commonly used non-ferrous metals (properties, inventories, recovery and recycling). Theses also deal with e-waste and its management. Key words: non-ferrous metals, recycling, utilization
Agricultural waste treatment
Schneider, Martin ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
As a result of the deteriorating state of the environment due to intensive industrial and agricultural production activities, it is necessary to proceed to the pressure on polluters, both legislatively and economically. Slurry as a by-product is a valuable complex organomineral fertilizer. Its fertilization value is comparable with manure, nitrogen, phosphorous and potassium fertilizers. Moreover, the slurry has a significant content of organic substances. Slurry as a fertilizer is important especially today, when the czech agriculture has a great deficiency of manure caused by reduction in cattle. That s why slurry is an important alternative of fertilizers with biological origin with no pollutants. After production slurry contains many biologically harmful substances, so it s necessary to store it in slurry basins. Chemical and physical reactions during a period of four to six months cause, that slurry is rid of unwanted substances and qualities.
The study of water quality in wells Protected Landscape Area Křivolkátsko
Vobecká, Kateřina ; Benešová, Libuše (advisor) ; Tonika, Jaroslav (referee)
The water quality is an essential abiotic factor of the environment, particularly for water-linked ecosystems. It also necessary for human society for which the absence of drinking water could have disastrous consequences. This diploma thesis is focused on small resources of groundwater located in the protected area Křivoklátsko - the springs and wells. A water from the monitored wells was subjected to basic physico-chemical analysis plus some of these wells were also tested for microbiological contamination. These results were presented against current legislation and were also compared with results from Tomáš Brabenec's bachelor thesis. Key words: Křivoklátsko, wells, springs, water quality
