Abstract

The aim of this project is to study the wastewater treatment system of Sahand dairy products factory and to provide a solution for the problem. The existing wastewater treatment system in this factory is an anaerobic and aerobic system, where the aerobic system is an extended activated sludge. This study had two phases as follows: Phase One: This phase lasted from February 1, 2003 to September 1, 2004. Based on the integrated sampling, the company's wastewater was estimated to be approximately 100m3 per day. In this phase, the efficiency of anaerobic treatment system was investigated. The parameters measured in this study were BOO, COD, N03, P04, TS, OIL, and grease. After the samples were analyzed, the removal efficiency of the organic elements turned out to be low for the anaerobic system in winter. Phase Two: This phase lasted from September 1, 2004 to December 29, 2004. To increase the efficiency of the anaerobic system, a fixed-bed was installed. As a result of the improvement of the system, the following findings were obtained for the two years of 2003 and 2004: - An increase in the BOd removal efficiency from 30% to 61.4% - An increase in the COD removal efficiency from 45% to 64.6% - An increase in the N03 removal efficiency from 58.5% 82.8% - An increase in the TS removal efficiency from 63.8% to 67.9% - For the P04 removal efficiency, no significant difference was observed. The results for the aerobic system after its improvement are as follows: - An increase in the BOd removal efficiency from 83% to 90.5% - An increase in the COD removal efficiency from 82.2% to 92.2% - An increase in the TS removal efficiency from 72% to 80% - For the P04 and the N03 removal efficiency, no significant difference was observed.
