The invention discloses a biogas production-desulfurization integrated device, the main body of which comprises a biogas production section I, a three-phase separation section II, a sulfur separation section III and a biogas desulfurization section IV, wherein the bottom of the biogas production section is provided a dredge pipe, and a water inlet pipe, a sampling pipe and a return pipe are arranged on the wall of a reaction barrel; a sludge deposit chamber, a three-phase separator in an inverted funnel shape and a first gas chamber are arranged in the three-phase separation section, and an overflow water outlet pipe and a spray liquid return pipe are arranged on the wall of the barrel; an inclined plane spray liquid storage groove is arranged at the inner part of the sulfur separation section, and an air inlet pipe, a biogas inlet pipe and a tapered gas distributor are longitudinally arranged on the storage groove board surface; a spray liquid level pipe is arranged at the center of the storage groove, and a gas monitoring and sampling pipe and a sulfur exhausting pipe are arranged outside the barrel wall; and the bio-packing, a dish-shaped spray head and a third gas chamber arearranged at the inner part of a biogas desulfurized section, and a biogas output pipe is arranged on the barrel wall. In the invention, an anaerobic reactor integrates with a biocatalytic desulfurization device, and the H2S is removed from the gas phase, thereby promoting the release of the H2S in the liquid phase.
Description
technical field [0001] The invention relates to an anaerobic treatment device for organic wastewater, in particular to a biogas production-desulfurization integrated device. Background technique [0002] Biogas fermentation is one of the important means of organic wastewater treatment. Biogas fermentation technology is favored by environmental engineering circles due to low operating costs, low sludge output, and recyclable biogas. Domestic sewage contains 3-6mg / L organic sulfur and 30-60mg / L inorganic sulfur, and the sulfate content of some industrial organic wastewater (such as pulp wastewater, tannery wastewater, pharmaceutical wastewater, etc.) is even as high as 9000mg / L or more. During the anaerobic biological treatment of these sulfur-containing wastewater, a large amount of hydrogen sulfide gas will be produced, with a concentration of about 1-20g / m 3 . Hydrogen sulfide is a highly toxic and harmful gas. In the air and under humid environment conditions, hydrogen...
