Opis:: The aim of this study was to determine the biodegradability of organic and biogenic contaminants in wastewater flowing into biological reactors in the treatment plant in Nowy Targ. The research period covered the years 2016 and 2017, when 87 samples of raw wastewater and 87 samples of wastewater after mechanical treatment were collected and subjected to physico-chemical analysis. In both types of wastewater, the size of the following indicators was analyzed: BOD₅, COD, total kjeldahl nitrogen (TN) and total phosphorus (TP). The study verified the amount of pollutants in the raw wastewater in order to determine whether they are household wastewater. In the next stage of the analysis, the characteristic values of the analyzed indicators in wastewater after the mechanical treatment process were determined in order to indicate mutual dependences of organic and biogenic indicators. Based on the analysis, it was found that wastewater after mechanical treatment (in the case of its susceptibility to biological decomposition processes of organic pollutants) has an unfavorable COD/BOD₅ ratio. With regard to the susceptibility of wastewater to nitrification, denitrification and dephosphatation processes, in the majority of cases, wastewater is susceptible to these processes. It is recommended to apply an additional source of organic carbon to wastewater prior to biological treatment in order to improve the biodegradation of the analyzed pollutants.

Opis:: The objective of the work was to design a biological reactor in the Bardenpho system as an alternative to the SBR biological reactor in the wastewater treatment plant in Nowy Targ. The technological system of the newly designed biological reactor was adapted to the existing reinforced concrete structure. The design of individual nitrification, denitrification, predenitrification and dephosphatation chambers was developed on the basis of actual data on the volume of influent sewage and its pollutant loads. The newly designed technological system of the Bardenpho type biological reactor guarantees high efficiency in the elimination of organic and biogenic compounds from wastewater. Within operational guidelines, it is proposed to gradually eliminate the inflow of foreign waters to the sewage system by removing the illegally connected roof gutters. Moreover, it is recommended to strictly control the volume of the fur-plant industrial sewage discharged into the sewage system.

Tytuł:: The Interdependence of Organic and Biogenic Pollutants Concentrations in the Aspect of their Susceptibility to Biodegradation – A Case Study

Opis:: The aim of the research was to determine, the interdependence between COD and such parameters as: BOD5, TN and TP in raw wastewater and in mechanically treated wastewater using statistical methods, which would allow estimating the values of these parameters based on COD. Moreover, the aim of the study was to determine the susceptibility of wastewater before and after mechanical treatment to decomposition of organic and biogenic pollutants. The research was conducted from 2006 to 2015 in a collective wastewater treatment plant in Nowy Sącz. During the research period, 120 samples of raw and mechanically treated wastewater were collected and analyzed once a month. In the analytical part of the research, the quality of sewage was characterized, the strength of correlation of the examined indicators was determined and the susceptibility of sewage to biological decomposition was assessed. On the basis of the analysis it was found that knowing the value of the COD parameter it is possible to determine the values of the other indicators, i.e. BOD5, TN and TP. Moreover, it was shown that wastewater is largely susceptible to the biological decomposition of pollutants, and during the period when the inflow of sewage with reduced susceptibility occurs, the wastewater with high content of organic carbon should be dosed.

Tytuł:: Untypical Draining Barriers Efficiency as a Method of Pollutants Limiting in the Groundwater Reservoir

Opis:: The main aim of the paper was to formulate a proposal of using the draining barriers as a method of limiting pollutants in the groundwater reservoir. Primary processes of pollutants migration and examples of functioning the draining barriers work against the spread of various pollutants in the groundwater were indicated. An untypical kind of draining barrier, i.e. wells which were designed as a hydrogeological borehole to exhaust water intended for consumption, was selected as the research object. For analytical purposes, the available archival results of the physicochemical analysis of groundwater exhausted from the wells, located in the water intake so-called “belt D” in Kraków-Nowa Huta were used. The database was analysed by specialist programs, and the dispersion migration of pollutants from the existing metallurgical waste dump “Ruszcza” in time was presented. Temporary and spatial variability of the physicochemical parameters of groundwater was done during the analysis. The analysis was performed both in the draining barriers wells and in the intake boreholes. A geostatistical analysis of the variability of pollutant spread in the groundwater medium was a vital factor in the appraisal efficiency of the draining barriers operation. It was shown that the highest contents of the researched substances were present in the wells, which are located the nearest of metallurgical waste dump “Ruszcza” and are thereby the wells co-forming draining barriers. The efficiency of draining barriers was found after a thorough analysis.

Opis:: This paper presents the analysis and evaluation of the impact of clean sewage on the water in the Mordarka river, in the period 2012–2015. The analysis was conducted based on the collected and statistical research: the amount and composition of the purified sewage discharged to the receiver. The following pollution indices were tested: total suspended solids, BOD₅, COD, total nitrogen and total phosphorus. On the basis of the obtained results it was concluded that the amount of purified wastewater discharge to the Mordarka river, did not contribute to the degradation of the water quality in that period of time. Moreover, the level of indicators: total suspended solid, BOD₅ and COD did not exceed the limit values from the regulation, which confirmed the effective protection of water quality in the Mordarka river. However, because of the high concentration of biogenic compounds in the purified wastewater effluents, the river is prone to eutrophication process.
