| Summary: | Wastewater from food processing enterprises is a strong organic-polluted wastewater. It contains mostly organic compounds, which fits to be treated by using biotechnology. The best technology for treatment is anaerobic. Deodorization is one of the most important points of this
technology since anaerobic process generated some odor compounds. The main reason which causes bad smell in wastewater was a present of compounds which contains N and S. In this paper
we report the result of deodorization by using several oxidant agents. The deodorization was taken after anaerobic process. The result shown that at pH 7-8.5, 4 gram/l of CaO or 120 milligram/l of CaOCl2, 2.4 milligram/l of KMnO4 or 1.6 ml/l of H2O2 can be useful separately. The recommendation is using of CaOCl2 for the best economic choice. |
