ABSTRACT
Aim of the study:
The aim of the research was an evaluation of efficiency of rural sewage treatment in a wastewater treatment plant with sequence reactor (SBR).
Material and methods:
The efficiency of pollutants removal in the treatment plant was evaluated with use elements of theory of reliability. Research carried out in period from March 2014 to December 2015. The content of pollution in treated wastewater were compared with limits values contained in Regulation of the Minister for Environment of 18 November 2014. The evaluation of efficiency of contamination removal in the plant was made with use elements of the theory of reliability for following indicators: BOD5, CODCr and total suspension. As a basis for calculation reliability indicator WN, index of technological efficiency of treatment (Pso).
Results and conclusions:
Based on analysis of treated wastewater, for three parameters, it was stated, that analysed wastewater treatment plant works correctly. Limits values contained in Regulation of the Minister for Environment of 18 November 2014 (Dz. U. 2014 poz. 1800) for the analysed pollutants was not exceeded. Also in case of all examined parameters high percent of its reduction was observed, which was from 96% for CODCr to 99% for BOD5. Also values of reliability indicators confirm its very good working.
