Embodiment Construction

[0018] The waste water treatment process of the present invention consists of seven parts, namely the water inlet section, the water return section, the water distribution section, the filler section, the biogas desulfurization section, the biogas return section, and the drainage section. By adding composite fiber filler to the reactor, Provide a place for the production of microorganisms; and reasonably match the acid-generating filler and gas-generating filler in the filler contact reaction zone to provide the best reaction conditions for anaerobic acid and gas production; at the same time, biogas desulfurization technology is used, and through Part of the biogas backflow reduces the sulfide content entering the gas production section, thereby eliminating the inhibitory effect of hydrogen sulfide on methanogens; also uses two-phase backflow of water and biogas, water backflow can dilute the pollutants in the water, and the generated biogas is desulfurized Reflux after treatme...

Abstract

An anaerobic treatment device for treating sewage with sulfate radicals and organic matters can be used for treating the sewage with high sulfate radical concentration and high organic concentration and is characterized by comprising an anaerobic bioreactor which is, from top to bottom, provided with a water distributor used for sewage distribution, a filler acid-generating section used for sewagecontact reaction so as to acidify the organic matters and reduce the sulfate radicals, a filler gas-generating section used for conducting contact reaction on effluent from the filler acid-generatingsection so as to generate marsh gas, and a water discharge section; the top of the anaerobic bioreactor is connected with a marsh gas devulcanizer by a marsh gas collecting pipe; the marsh gas devulcanizer is connected with the filler acid-generating section by a gas collector and a marsh gas reflux pump; and the water discharge section is provided with a water outlet and connected with a water reflowing opening of the water distributor by a water reflux pump.

Description

technical field [0001] The invention relates to an environmental protection technology for waste water treatment, in particular to an anaerobic treatment device for treating waste water containing sulfate radicals and organic matter, and the anaerobic treatment device can be used for the treatment of waste water with high sulfate radical concentration and high organic concentration. Background technique [0002] The treatment of wastewater with high sulfate concentration and high organic pollutant concentration has always been a difficult point in the field of water pollution control. It is necessary to remove sulfate and organic pollutants in wastewater at the same time. Wastewater with high concentration of organic pollutants containing high sulfate concentration has a high concentration of sulfate radicals (thousands of mg / L) and high concentrations of organic pollutants (up to tens of thousands of mg / L), so it is necessary to effectively treat such wastewater Generally, ...
