Effect of leachate recirculation on physical and chemical properties of urban solid waste by anaerobic aerobics digestion and agitation

Abstract

This research project focuses on the study of the effect of leachate recirculation on the physical and chemical properties of solid waste under anaerobic, aerobic digestion and agitation. To do so, a review of the literature was performed, it had to be relevant for the research objetives, and they were leaching soil bioreactor systems, physical and chemical parameters of soil resources. It was analyzed the lixiviated generated on the market La Hermelinda, submitted to three processes where each one of them performs with different special natures. Likewise it was evaluated the parameters of acidity (pH), conductivity, temperature, humidity and muffling capacity. Three systems were analyzed: anaerobic, aerobic and of agitation: Each system worked with further 200.15g of earthen sample 100 mL of water itself. Experimentation was carried out for five days, then the respective analyses and data obtaining was done. It Was Concluded That all the systems changed in the resulting parameters were generated, results for pH were obtained were proven to be of average pH of 6,466 – 7,818, the average humidity in percentage of 2, 80 % – 20, 39%, an average temperature of 24,02 °C - 26,04 °C, an average conductivity of 1,154 - 1,97 (20-200ms). The lixiviated characterizes for the high contents of organic and inorganic matter, also by the high contents of heavy metals.
