jaue20130019: Urban Landfill Concentrate Recharge to Remove Organic Matter Research

Abstract

In this paper a simulated recharge reactor to concentrate the injection processing were studied, discussing the effect of removal organic contaminant concentrate injection. Through the experiment can be confirmed: concentrate injection has good removal efficiency of organic pollutants, the concentrate injection to the anaerobic landfill body on its COD removal rate was 81.56%, the removal of BOD5 was 82.5; Concentrate loading oxygen injection or landfill body on its COD removal rate was 91%, the removal of BODs was 98.69%. Adjust the pH value is about 9 injection will concentrate on the removal rate of organic pollutants is higher than to other pH; Concentrate to 20 weeks after injection the settlement of the landfill body amplitude is settlement of the landfill body not injection amplitude of 3.75 times.
