Abstract

The invention relates to a high-load composite anaerobic reactor for treating high-suspension solid materials, and belongs to the technical fields of environmental protection and biomass energy sources. The anaerobic reactor comprises a circulating pump 2, a water distributing device 3, an anaerobic reactor body, an external circulating pipe (pot) 5, a top discharge opening 9, a sludge-water separator 10, and a sludge reflux pump 11, wherein the anaerobic reactor body is divided into a granule sludge bed region 4, a buffer region 6, a flocculent sludge bed region 7 and a gas collecting chamber 8 from bottom to top according to liquid flow speed difference and sludge characteristics. The anaerobic reactor is characterized in that the anaerobic reactor is the high-load composite anaerobic reactor, three separators are not arranged in the reactor, but the sludge-water separator separated from the anaerobic reactor is designed. The high-load composite anaerobic reactor disclosed by the invention realizes the purpose that when one anaerobic reactor is used, multifunctional requirements for anaerobic digestion, being plugging free, being maintenance free, simple structure, small occupied space, low construction cost, high inefficiency and the like of high suspension solid organic waste water, organic serosity and sludge can be met.

Description

technical field [0001] The invention relates to a high-load composite anaerobic reactor for treating high-suspended solid materials, which include high-suspended solid organic wastewater, organic slurry, and sludge, etc., and produce valuable biogas, belonging to Environmental protection and biomass energy technology. Background technique [0002] The anaerobic treatment of high suspended solids organic wastewater, organic slurry and sludge to generate economically valuable biogas is one of the key technologies in the fields of environmental protection and biomass energy in recent years. The anaerobic reactor has also experienced the first-generation anaerobic digestion process represented by anaerobic digestion reactor (CSTR) and anaerobic contact process to the upflow anaerobic sludge bed (UASB) reactor, etc. The second-generation anaerobic digestion process, and then to the development process of the third-generation anaerobic reactor represented by anaerobic granular sl...
