Analysis of the comprehensive management of sewage sludge in Poland

摘要

The methods of sewage sludge management in Poland have largely been determined by the legal requirements related tothe Poland’s membership in the European Union. Since 1st January 2016, sewage sludge landfilling is prohibited. It mustbe emphasised that legal changes regarding wastewater management, along with the systematic increase in the volume ofproduced sludge, entail the necessity to change the existing method of sewage sludge management. This paper contains ananalysis of solutions for management of sewage sludge produced in Poland over the period of 8 years. The goal of the workwas an assessment of comprehensive management of sewage sludge produced in Poland from 2009 to 2016. Despite thedecrease in the agricultural use of sewage sludge, their average share of 32% was the highest among other forms of sewagesludge management in Poland. Another form, related with the final stage of sewage sludge management, concerned its thermalprocessing. It was treated as a promising method, with a 19% increase over the analysed period. An optimal solution shouldbe found to ensure safe management of sewage sludge.
