Abstract: | Wastewater from nitrochlorobenzene and dinitrochlorobenzene production comams many narudegradable organic matters, such as: nitrophenol, nitrochlorobenzene, dinitrochlorobenzene, nitrobenzene and so on. Using catalytic oxidation technology to treat the said kind of wastewater under room temperature and atmospheric pressure could obtain good effect, the removal rates of chroma and CODcr were above 98% and 70% respectively, and the biodegradability of the wastewater was improved. The mechanism of catalytic oxidation technology treating wastewater under room temperature and atmospheric pressure was elaborated; besides, the process flow, type selection of main equipments, operating condition and main economical and technical indexes were introduced at the same time. |
