摘要

One of the most important concerns in Tehran munici pal landfill is the production of leachate and its potential for water resources pollution. This study was undertake n to examine feasibility of biological and physico/ chemical treating of high-strength landfill leachate that wa s collected from Tehran municipal landfill for roug hly 50 years. The aim of this study was to estimate the optimal c oncentration of leachate in the reactor influent an d process parameters on the base of aerobic digestion efficie ncy. An innovative method based on the membrane bio reactor (MBR) technology was developed to treat landfill le achate over 32 days. Water quality parameters, such as pH, dissolved oxygen, nitrate, nitrite, Biochemical Oxy gen Demand (BOD 5 ) and chemical oxygen demand (COD) were measured daily. A decrease of more than 89% was ach ieved for a COD of 320 mg/L in the initial leachate . Ammonia was decreased from 2720 mg/L to 0.046 mg/L, while the nitrate concentration in the effluent de creased to 70.2 mg/L. The bacteria in the MBR system adjusted to the presence of the leachate, and increased 4 or ders of magnitude. Heavy metals were removed by at least 82 .7%. These successful results demonstrated the MBR technology is feasible, efficient method for the tr eatment of municipal landfill leachate.
