Sewage and it's cleaning at sewage water treatment plant in the village Ostrožská Lhota
VANĚČKOVÁ, Hana
All of us produce large volume of wastewater every day. But we care about the environment more and more which brings building of new sewerage plants as well. Nowadays, there is an intensification of old sewerage plants and many new ones are being built. In the past, sewerage plants belong only to the cities, but now they can be found even in the villages. People should also know what they release into sewerage and they should be aware of it. We should not rely only on a sewerage plant because it can not remove all the unwanted substance either. In my bachelor´s work on the theme ?Wastewater and its treatment in the sewerage plant in the village Ostrožská Lhota?, I deal with the present status of the sewerage plant in the village, the wastewater treatment system and wastewater in general as the theme indicates. The work is divided into two essential parts ? the theoretical and the practical one. Firstly, I described the former wastewater discharge in the theoretical part. Then I described the wastewater division and wastewater itself. Finally, I wrote about the sewerage plant, mainly about wastewater supply and its subsequent circulation. The next part is the practical one. My own research was a part of it. It was a quantitative form of research. The research was done by the method of questioning, in the form of questionnaires. The questionnaires were distributed to the residents of Ostrožská Lhota, people above 18. It was a random sample of people. 130 questionnaires were distributed in total. The obtained data are processed and analysed by means of charts. The secondary data analysis which was done by means of measuring data on inflow and outflow belonged to the practical part as well. Afterwards, the data were processed into charts. I set three goals in the work. The first goal was to evaluate the wastewater quality before the construction of the sewerage plant in the village Ostrožská Lhota. The second goal was to evaluate the effectiveness of wastewater treatment in the sewerage plant in the village. I tried to reach these two goals by means of secondary data analysis where I use the chart of measuring data on water inflow and outflow. I compared these figures with the limits of measurement ? limits which are set for the sewerage plant by the water resource management. I found out that the sewerage plant meets all the requirements and it does not exceed the limits. The measuring data are even below the limits. Lastly, the third goal was to find out the households´ opinion on wastewater pollution. I investigated on this goal by the help of the questionnaires. All the set goals were fulfilled. The testing results show that wastewater satisfies the limits of the water resource management and the people are aware of the discharged wastewater quality. This bachelor´s work can function as a recommendation when potential insufficiency is found. It can be also an educational material for non-professionals who do not know this topic and questions.
