| Abstract: | Objective ] The study aimed to discuss the optimal conditions for the treatment of nucleotide Wastewater by microwave induced oxi- dation process. Method ] Nucleotide wastewater was treated by microwave induced oxidation process＇, and the effects of microwave power, mi- crowave time, oxidant dosage and pH on the removal rate of COD and B/C ratio as well as the optimal conditions were discussed through an or- thogonal test. Result] Oxidant dosage affects the removal rate of COD most greatly, followed by microwave power and time, while the impact of pH is the smallest. The best conditions are as follows .. pH = 1.0, oxidant dosage 24 g/L, microwave power 800 W, arid microwave time 3 min. Under the best conditions, the removal rate of COD reaches 78.2%, and B/C ratio increases from 0.005 to 0. 150, that is, the biode- gradability rises by 30 times. Conclusion ] The research can provide scientific references for the treatment of nucleotide wastewater in future. |
