Abstract

Background and Objective: Heavy metals and dyes are released into the environment by industrial activities and technological development more than natural. Because of their toxicity, they have anomalous effects on the environment and on the health of organisms, especially humans. Method: In this research, two methods of advanced oxidation and biological adsorption were combined in a single reactor and the pollutants were introduced into the reactor and the percentages of their removal were investigated. . The UV / H2O2 process was used to remove the RBB dye and to remove the manganese ion from a biological adsorbent fixed in Sodium alginate. After performing these two processes in the batch system and considering the optimum conditions in the unit reactor, these two processes were combined and the granules were poured into a polyethylene filter and placed inside the reactor embedded in the center of the UV lamp. Findings: According to the results of TOC and COD, it was found that in the case of only UV / H2O2 process, the percent removal of TOC and COD were 35% and 79. 5%, respectively, but in the combined condition, the percentage of TOC reduction was 56% and COD It reaches 90. 22%. Discussion and Conclusion: The results have shown that the removal efficiency both in terms of decolorization and mineralization is negligible when UV, H2O2 or biosorbent are used alone. Among combining AOP with-biological process schemes tested, we found that the UV/H2O2/biosorbent process was the most effective in reducing the COD, color and TOC of decolorization
