    Opis:
    Odorous substances emitted to ambient air from wastewater treatment plants cause a serious nuisance to inhabitants in the direct vicinity of such emitters. The solutions currently used to remove malodorous gases in the Wastewater Treatment Plant in Belchatow do not fulfill their function properly. This article presents the test results of the composition and concentrations of odorous compounds emitted from the abovementioned plant. In addition, the paper introduces the concept of eliminating substances by the biofiltration process. Due to the applied method, one can expect to reduce the odor by at least 90%.

    Opis:
    The degradation of pentoxifylline (PTX) using H2O2, UV, H2O2/UV, Fenton and photo-Fenton processes has been examined in aqueous solutions. The influence of oxidation agent and initial PTX concentration, on H2O2, H2O2/UV, Fenton and photo-Fenton reactions was investigated. The addition of inorganic ions (Cl–, NO3–, SO42– and CO32–) on the degradation efficiency of PTX was tested for H2O2/UV, Fenton and photo-Fenton processeses. The results indicate that the photo-Fenton reaction is the most sufficient for PTX removal. The complete pharmaceutics decomposition is achieved after 5 min under optimized concentration of FeSO4,·7 H2O2 and H2O2. The degradation of PTX is inhibited in the presence of inorganic matter in H2O2/UV and Fenton reaction. In the photo-Fenton process addition of above compounds does not affect the reaction rate. Structures of ten products of photo-Fenton reaction have been proposed.

    Opis:
    The effectiveness of co-treatment of leachates from an old site of municipal landfill with a dairy industry wastewater in a membrane bioreactor has been investigated. The subjects of the study were leachates collected at the municipal landfill in Tychy and dairy wastewaters from Dairy Plant in Bieruń. The determination of the most effective technological parameters of the process, i.e. activated sludge load and its concentration and types of COD fractions in the reactor influent was made. It was shown that the activated sludge load at the level of 0.06 g COD/(gDM·d) was the highest permissible one among all the investigated loads and the process run effectively within the whole investigated range of concentrations of activated sludge in a bioreactor. It was found that in the treated wastewater, the fraction of easily degradable organic compounds was the dominant one.

    Opis:
    The paper discusses the use of an artificial neural network to control the operation of wastewater treatment plants with activated sludge. The task of the neural network in this case is to calculate (predict) the readings of the probe measuring the concentration of nitrate nitrogen (V) in one of the biological reactor tanks. Neural networks are known for their ability to universal approximation of virtually any relationship, including the function of many variables, but the process of "training" the network requires the presentation of many sets of input data and corresponding expected results. This is a difficulty in the case of wastewater treatment plants, because some key process parameters are usually not measured online (samples are taken and measurements are taken in the laboratory), and even if they are, the time intervals are large. Bearing in mind the aforementioned difficulty, this work uses a set of input data consisting only of information that can be measured with measuring probes. As a result of the conducted experiments a high compliance of the probe's prediction with the expected values was obtained. The paper also presents data preparation and the network "training" process.

    Opis:
    The aim of the research was the evaluation of wastewater management in terms of stability and efficiency of wastewater treatment, using statistical quality control. For this purpose, the analysis of the operation and operation of the “Kujawy” Sewage Treatment Plant was made, which is one of the most important and largest sewage management facilities in the city of Cracow. This assessment was done using control charts x for 59 observations. The analysed research period covered the multi-year from 2012 to 2016. Five key pollutant indicators were used to evaluate the work of the tested object: BOD5 , CODCr, total suspension, total nitrogen and total phosphorus. In the case of the majority of them, based on the analysis of control charts, full stability of their removal was found in the tested sewage management facility. The exception was total nitrogen, for which periods of disturbed stability of its disposal processes were noted. Analysis of the effectiveness of wastewater treatment showed each time that the required efficiency of reduction of the analysed pollution indicators in the “Kujawy” Sewage Treatment Plant was achieved.
