Porównanie efektywności biologicznego usuwania związków biogennych w procesach MUCT i A2/O na przykładzie oczyszczalni w Gdańsku
Abstract
This paper presents a comparison of the efficiency of nutrient removal in two different technological systems functioning in WWTP in Gdansk. The upgrade was necessary in order to adjust the parameters of wastewater treatment to more stringent requirements for Total Nitrogen removal (Total Nitrogen concentration < 10 mg/L). Since 2012 the biological treatment line has operated based on modified A2/O process instead of MUCT process. The modernization were carried out in 2009-2011. The analysis of wastewater quality showed that the average daily effluent of total nitrogen (TN) concentration was decreased from 11 to 8 mg TN/L after 2011. Moreover, average the daily effluent of total phosphorus (TP) concentration was reduced from 0.5 to 0.3-0.4 mgTP/L. It demonstrates that despite of the slight but continuous deterioration of wastewater quality, the modified A2/O process is more efficient than MUCT process in terms of biological nutrient removal. As a result of WWTP modernization the quality of discharged wastewater already meets the requirements set by the Regulation of the Ministry of Environment from 18th November 2014 and recommendation of HELCOM organization especially in terms of conditions of biogenic compounds removal from wastewater.
