The present invention relates to a kind of industrial wastewater anaerobism desulfurizer and techniques for technical field
Background technique handles the industrial wastewater containing high concentration sulfate using anaerobic bio-treated method, for example pharmacy is given up
Water, food wastewater, dyeing waste water etc. are a kind of relatively effective processing techniques.The main quilt of sulfate in Anaerobic biotreatment method
Sulfate reducing bacteria is reduced to hydrogen sulfide and removes.But sulfate reducing bacteria and methanogen in single-phase anaerobic reactor
Between can to substrate occur competitive relation.Sulfate reducing bacteria is in competition H2It is dominant with when acetic acid in dynamics and thermodynamically
Gesture, the energy discharged is more than methanogen, and reduzate hydrogen sulfide also can generate inhibiting effect, shadow to methanogen
Ring the amount and quality of final methane phase.
Two-phase anaerobic reactor can then remove sulfate and methane phase process carries out separation spatially, so that big portion
Divide sulfate mutually to be removed in acidification, reduces the influence to methanogen in methanogenic phase.However, acidification phase in addition to
Individual strains such as Desulfotomaculum and Desulfomonas can be used glucose as directly except electron donor, other are big
Part of sulfuric acid salt reducing bacteria can only utilize H2And the small molecule volatiles fatty acid such as acetic acid, propionic acid, lactic acid is as electron donor.Root
According to Thermodynamic Law, the electron donor that sulfate reducing bacteria utilizes at first is hydrogen, but hydrogen pipeline exists between microbial species
Acidification, which is compared in short hydraulic detention time, causes hydrogen partial pressure to increase, so that reactor is acidified, influences the removal effect of sulfate.
