The invention discloses a self-circulation ferric salt desulfurization anaerobic reactor. A reactor main body is provided with an anaerobic reaction system and a ferric salt desulfurization system; the anaerobic reaction system is provided with a water distribution region, a reaction region, a separation region and a backflow region; the ferric salt desulfurization system is provided with a ferric salt desulfurization region and a ferric salt regeneration region. Hydrogen sulfide generated in the reaction region is guided into the ferric salt desulfurization region after passing through the separation region and is oxidized into elemental sulfur through ferric iron; a product, namely ferrous iron, is guided into the ferric salt regeneration region and is oxidized into the ferric iron; the ferric iron automatically flows to the ferric salt desulfurization region, so that the ferric salt is recycled. According to the reactor, the anaerobic reaction system is integrated with the ferric salt desulfurization system, and the air pollution caused by H2S leakage can be prevented; H2S is oxidized into the elemental sulfur, so that sulfur resources can be recovered; the ferric salt is recycled, so that the desulfurizer consumption can be reduced; the desulfurization operation is performed by ferric iron instead of oxygen, so that the explosion risk caused by mixing of methane with oxygen can be lowered and the safe production is realized.
Description
technical field [0001] The invention relates to a desulfurization anaerobic reactor, in particular to an iron salt self-circulation desulfurization anaerobic reactor. Background technique [0002] With the increasingly prominent environmental and energy issues, anaerobic biotechnology is favored by people because it can eliminate pollution and recover energy. However, when using anaerobic biotechnology to treat industrial wastewater, agricultural wastewater and domestic wastewater, it is easy to convert the sulfate and sulfide contained in the wastewater into hydrogen sulfide and release it. Hydrogen sulfide is a toxic and harmful gas, which has the following hazards: inhibiting the activity of anaerobic functional bacteria, affecting the efficiency of anaerobic treatment; emitting foul odor; toxic, affecting human and biological health; corrosive, corroding pipelines, equipment and instruments, etc.; burning Produce sulfur dioxide and cause secondary pollution. my country...
