Abstract

Under aerobic and anaerobic conditions, two laboratory-scale reactors were operated. Each reactorwas packed with 8.5 kg of shredded synthetic solid waste (less than 5 cm) that was prepared according to anaverage composition of domestic solid waste in the city of Kirkuk. Using an air compressor, aerobicconditions were created in the aerobic reactor. This study shows that the aerobic reactor was more efficient inCOD and BOD5 removal which were 97.88% and 91.25% while in case of anaerobic reactor, they were66.53%and 19.11%, respectively.

Highlights

The city of Kirkuk, like most metropolitan cities, experiences considerable problems associated with the management of municipal solid waste (MSW)
Previous studies on aerobic decomposition procedures have shown that the putrescible components of the waste can be decomposed faster under aerobic conditions than under anaerobic decomposition
The main aim of the present study is to explore the impact of leachate recirculation and aeration compared with various other alternatives that are available for sanitary landfilling and to provide information for the effective operation of the Kirkuk sanitary landfill

Summary

Introduction

The city of Kirkuk, like most metropolitan cities, experiences considerable problems associated with the management of municipal solid waste (MSW). Several studies have shown that waste decomposition can be enhanced by an increase in the water flow owing to the enhanced flushing and dilution of inhibitory materials. This process maintains a favorable environment through the consistent moisture distribution and addition of higher quantities of inoculums and nutrients [3,5,6]. There has been an increased interest in the addition of air into the landfill mass for aerobic solid waste decomposition[4]. The concept of aerobic decomposition by the injection of air into the body of landfill offers considerable benefits in waste management both for existing and new systems [8]. The main aim of the present study is to explore the impact of leachate recirculation and aeration compared with various other alternatives that are available for sanitary landfilling and to provide information for the effective operation of the Kirkuk sanitary landfill
