Abstract
The utility model relates to a double-layer soluble cyclone flow enhanced internal-circulation-type anaerobic reactor. The anaerobic reactor mainly comprises a sewage pump, an ejector, a water distributor, a reactor tank body, a reflux pipe, a lifting pipe, a three-phase separator, a gas-liquid separator and a gas buffering tank, wherein marsh gas in the buffering tank seriously hits against sewage at a throat pipe of the ejector, so that big gas bubbles are dispersed into a plurality of extremely small gas bubbles which are mixed with the sewage so as to form soluble gas; the soluble gas enters the water distributor and then is sprayed out at a high speed along the tangential direction of the inner wall of the tank body, and two strands of cyclone flows can be formed in a spraying manner respectively through four spraying nozzles on the upper surface and the lower surface of the water distributor. Thus, granule sludge can be effectively driven to perform cyclic motions under double functions of the cyclone flows and the gas stripping. Therefore, the mixing and mass transfer conditions of microorganisms and substrates are fully improved. The anaerobic reactor is particularly suitable for biochemical reactions of reactors with large diameters under the existence of high-concentration anaerobic bacteria and sludge so as to accelerate the sewage treatment, thereby obtaining the high purification efficiency of organic matters.
