Performance Evaluation of Hybrid Septic Tank and Aerated Lagoon Process Efficiency for Landfill Leachate Treatment
مقاله پژوهشی
Original Research Article
<p style="text-align: justify;"><strong><em>Background and Objective:</em></strong> In this research, landfill leachate treatment in Karaj city was investigated by a linked septic tank and aerated lagoon.<br>
<strong><em>Materials and Methods:</em></strong> At first, characteristics of the leachate were determined. Then a pilot plant with anaerobic-aerobic (Septic tank and Aerated lagoon) parts was installed and started.<br>
<strong><em>Results:</em></strong> Results showed that Chemical Oxygen Demand (COD) removal efficiency for septic tank and subsequently to lagoon for influent COD of 19537 mg/L, were 8401 and 432 mg/L, respectively. The septic tank and aerated lagoon also operated with different flow rates and the best results for septic tank and aerated lagoon obtained in 23.6 <a name="OLE_LINK16"></a><a name="OLE_LINK15">L/day </a>and 9.3 L/day respectively with maximum COD removal efficiency of 91.2%.<br>
<strong><em>Conclusion:</em></strong> According to the obtained results, the hybrid system had 90% COD removal efficiency. Therefore, leachate COD loading could be effectively removed in this system.</p>
