Along with the quickening of process of industrialization, high concentrated organic wastewater is processed the research focus that more and more becomes sewage treatment area.

UASB as the most conventional be also the Anaerobic Methods in Treating of effective high concentrated organic wastewater simultaneously, there is the technological merit of self uniqueness, UASB reactor is made up of bottom suspension anaerobic sludge layer, solid-liquid-gas three-phase separator and collection chamber. The anaerobic sludge layer of bottom is most crucial processing section, formed by the anaerobic sludge with good settling property and cohesion performance, sewage through thus layer upwards fully contact with suspension anaerobic sludge, realize organic anaerobic reaction overall process in sewage, produce biogas, form three kinds of phases of solid, liquid, gas simultaneously and mix mud layer, bubble contacts, merges in uphill process, changes from small to big, and sludge blanket has been played to the effect of pneumatic stirring, meanwhile, promote to mix mud layer rising and enter three phase separator. In the time that mixing mud layer runs into dividing plate, ascending current is folded to shunting, and biogas passes through water layer and enters collection chamber, collecting methane, enters settling zone, mud-water separation after muddy water mixed solution stream is folded to, mud condenses because waterpower changes, and forms granule sludge, anaerobism mud layer bottom again sinking back.

Internal-circulation anaerobic reactor (internalcirculationreaction, IC) is Dutch PAQUES company in 20th century the mid-80 on the basis of UASB reactor, succeed in developing the 3rd generation ultra high efficiency anaerobic reactor. By 1988, the IC reactor of the 1st productivity scale was thrown people's operation in Holland in the world, and up to the present, the production waste that is successfully applied to the industries such as Beer Brewage, papermaking, food processing, citric acid is administered. But still have the following disadvantages: (1) needs three phase separator reasonable in design and must cultivate well behaved granule sludge, the current domestic employing of three phase separator be horizontal sedimentation tank theory, its separating effect is unsatisfactory, causes part mud to run off with water outlet; (2) complex structure of reactor, water distribution inequality, muddy water mixes not bery even, is prone to the phenomenons such as local short stream, channel and dead angle.

As preferably, on the weir wall of downflow weir, have multiple V-arrangement overfalls, overflow water outlet collects through water leg, and is provided with apopore and is connected with outlet pipe.

As preferably, system control box is controlled water intake velocity, stirring intensity, oxidation-reduction potential value, pH value.

This utility model has following beneficial effect:

In the utility model, sewage, mud, biogas three form large circulation inside and outside guide shell, expand the contact interface of sewage and mud, and utilize energy dissipator to break up and stir the whirlpool forming, effectively destroy short stream and the dead angle of inhalant region, influent concentration in simultaneous buffering tank body, compensator interior body region concentration difference is more stable with the reaction environment of safeguards system entirety. This anaerobic reactor water conservancy stirs, and water inlet pipe mouth is difficult for stopping up, and has solved the short flow phenomenon of inhalant region and reaction zone, easily forms granule sludge, not only good sewage processing effect, and increased the generation of biogas.

The utility model utilizes water-seal principle that gas, liquid, solid three phase separation process substep is carried out, in gas-liquid separation zone, advanced promoting the circulation of qi and liquid-solid two-phase separates, the rising bubble increasing gradually separates with mud, sewage, bubble floating enters biogas chamber to liquid level, solid-liquid two-phase enters solid-liquid displacement zone and carries out separating of liquid phase and solid phase again subsequently, realizes efficient three phase separation. The utility model does not relate to complicated three phase separator structure.

The utility model is applicable to high organic concentration, high suspended matter wastewater treatment.
