The article presents results of research concerns amount and remove indices of nitrogen and phosphate in domestic sewage treatment plant. Analysis sewage treatment plants are objects working with method of active sludge. The first sewage treatment plant Turbojet EP-4 was installed in Pałecznica in province małopolska. The treatment plant works for Primary schools where about 100 children and theaters’ house inhabited 6 people. Second sewage treatment plant is called Biocompact BCT S-12 and was installed in Rajbrot village near Lipnica Murowana. It takes sewage from schools and a teachers’ house inhabited 12 people. Analysis of results of research concern four years 1999-2003, and in this time took sewers flow to and flow in to sewage treatment plants. The results of research of sewer analyzed statistical for characterize size concentration total nitrogen and phosphates in sewer. In analysis introduce frequency relativity of occurrence concentration indices of biogenic indices in clean sewer. Additionally characterize size of reduction indices in clean process. Composition in flow to sewer was type for living sewer. Mean reduction of biogenic indices was for nitrogen and phosphates for two treatment plant 63,6% and 51,4%. Mean values total nitrogen and phosphates in sewer flow to treatment plant Turbojet EP-4 ...
The study presents the characteristics of the catchment of Trzemna (Ciemna) River from the point of view of the likelihood of appearance and migration of biogenes. A climatological, hydrological and soil characteristics was prepared. Agricultural changes as well as changes in the water and sewage management system and waste management were analysed. Basing on the analyses of WIOŚ the author evaluated, among others, the changes in the concentration of total nitrogen, nitrates, total phosphorus and phosphates in the last few years. The changes in the content of nitrogen and phosphorus in the waters of Trzemna River were evaluated, taking into consideration the natural environment, as well as social and economic changes. The water of the Trzemna River, what is characteristic of it, has high phosphorus and nitrogen concentration. The highest concentration of nitrates is marked from January to May, in the period of rich plants growth it lowers visibly. In the cross-section of Szkudła the nitrate nitrogen form dominates, below the reservoir Gołuchów the concentration of organic and ammonium nitrogen raises, in the cross-section of Tursko, which is situated below the sewage drop from the treatment plant in Gołuchów, nitrates are less than 50% of the total nitrogen, noticeably, the ...
