Study on removal of organic pollutants using the Expanded Granular Sludge Bed Reactor

摘要

Slaughterhouse wastewater includes various and large concentrations of organic matter, which contributes paunch, feces, oil, fat, and lard, undigested foods, blood, suspended content, urine, loose meat, soluble proteins, excrement, compost, grit and colloidal particles. The aim of this analysis is to look at the viability of using EGSBR to treat slaughterhouse wastewater, as well as the effect of HRT on the organic removal yield. The experimental model was run with six average COD ranges of 1752, 1744, 1820, 2264, 2768, and 3176 mg/l in the influent. With a HRT of 4 days and an OLR of 0.081Kg COD/m3.day, the maximum effective organic removal was 90.17 percent. The experiment was carried out at a mesophilic temperature range to ensure that the organism grew efficiently. Scanning microscopy was used to examine the slaughterhouse wastewater at varying magnifications.
