| Abstract |
The emission of odor compounds is a serious problem for the environment. The complaints from the residents of nearby houses about discomfort indicate that this is not a sufficiently resolved problem and involves the need to take appropriate action. The article discusses the ecological method of using a biofilter, which is an installation for removing the odors generated in the process of solar drying of sewage sludge in a municipal wastewater treatment plant (WWTP). This technology is used in many Polish dryers, it involves sludge drying in the summer. Direct air outlet from the solar dryer causes the emission of these compounds, which can be a serious problem, especially in high-capacity WWTPs. One of the most ecological methods, which consists of directing the exhaust air through water scrubbers to the biofilter, was used in the described object. The analyses were carried out on a real object, examining the ratio of biofilter filling under various atmospheric conditions to the reduction of odor compounds formed. This solution, according to research, is an effective solution, but in such a system (solar dryer - biofilter), it is still not very popular. |
