in order to solve the problems of the prior art, technical scheme provided by the invention is: biogas air-flotation type anaerobic reactor, comprise anaerobic biological reactor body, in described anaerobic biological reactor body, be distributed with successively from bottom to up water inlet pipe and the water distributor of waste water, sludge bulking bed district, triphase separator, primary water rising pipe, it is characterized in that, it above the intrinsic triphase separator of anaerobic biological reactor, is anaerobism air supporting reaction zone, described anaerobism air supporting reaction zone is provided with out biogas pipe and return line extends to this external connection one dissolved air water preparation system of anaerobic biological reactor, dissolved air water preparation system connects the bubble reliever of triphase separator top through a dissolved air water water inlet pipe, on described bubble reliever, be provided with an air supporting protective guard.
preferably, also connect a chemical feed pipe in described anaerobism air supporting reaction zone.
preferably, the bubble of described air supporting protective guard outlet top is provided with tubular scum board, and described scum board top seal, bottom are open.Scum board is separated anaerobism air supporting reaction zone and disengaging zone, has effectively improved reaction efficiency and separation efficiency.
preferably, described air supporting protective guard top is disengaging zone, is provided with a transmission rig and connects the scum silica frost scraper plate driving.
preferably, described primary water rising pipe is located at disengaging zone.
the biogas that the present invention adopts anaerobic reactor to produce is made dissolved air water by dissolved air water preparation system together with anaerobic effluent partial reflux, is then incorporated into triphase separator top in anaerobic reactor and discharges.The material containing in the waste water such as oil-polluted water, difficult degradation suspended wastewater discharging in small bubbles and the anaerobic reactor forming adheres to, make its density be less than water and rise, air supporting is to reactor surface, remove air supporting scum silica frost by scraping scum silica frost equipment, clear water enters into subsequent disposal, reaches the object of wipe oil and hard-degraded substance.
the advantage of biogas air-flotation type anaerobic reactor of the present invention is:
1. the present invention adopts the biogas producing in anaerobic reactor system, make dissolved air water by dissolved air water preparation system and return anaerobic reactor, carry out air supporting processing, by anaerobism, cohesion, air supporting, skimming, precipitate, scrape mud and become one, COD removal effect strengthens 50%, and facility investment reduces 30%.
the advantages such as biogas air-flotation type anaerobic reactor of the present invention is simple in structure, floor space is little, it is very little to drop into, a little repair, power consumption is low, running cost is low, operational administrative is simple.
