Abstract

The aim of the work was to determine the technological reliability of the selected pollution indicators removal BOD5, CODCr and total suspension from the sewage treatment plant working with the bioreactor Pomiltek Mann type. Wastewater treatment plant which is a subject of this study is located in Lesser Poland, in Siepraw commune. The analysis was performed using the Weibull method for basic indicators of impurities, BOD5, CODCr and total suspended solids. Physicochemical analyses of raw and treated wastewater, were carried out in the period from 2003 to 2014 (11 years). The research period included measured values of pollutions indicators in 38 samples of raw and treated sewage. For each of pollution indicators descriptive statistic, percentage reduction (η) and treatment plant reliability factors (RF) were calculated. Average reduction for BOD5 and TSS was on level equal 94%, only for COD the average reduction was lower and was on level 89%. The reliability values determined by Weibull method, were: 75% (BOD5), 90% (CODCr) and 89.5% (TSS). The reliability results have been lower than the presented by literature source, which means that work of wastewater treatment plant in Siepraw was not satisfied in 11 years of research.

期刊介绍： Journal of Water and Land Development - is a peer reviewed research journal published in English. Journal has been published continually since 1998. From 2013, the journal is published quarterly in the spring, summer, autumn, and winter. In 2011 and 2012 the journal was published twice a year, and between 1998 and 2010 it was published as a yearbook. . Papers may report the results of experiments, theoretical analyses, design of machines and mechanization systems, processes or processing methods, new materials, new measurements methods or new ideas in information technology. Topics: engineering and development of the agricultural environment, water managment in rural areas and protection of water resources, natural and economic functions of grassland.
