Abstract

The present study demonstrates an appropriate technique for treatment of landfill leachate. Pretreat ment with alu m and anionic poly electrolyte as coagulant and flocculent materials caused 43% reduction of COD. Sucrose and nutrient broth were used for enrichment of sea water microflora. The pretreated leachate was used for determination of aerobic and anaerobic biological treat ments of sea water enriched microflora. BOD5, COD and TSS reduction were acquired in best samples 90.3%, 95.1% and 44.8% in aerobic and 31.2%, 38.3% and 37.3% in anaerobic conditions, respectively. The metal removal was determined in aerobic and anaerobic treat ments and up to 90% metal removal acquired in some cases.
