Example Embodiment

[0010] In order to further understand the content, features, and effects of the present invention, the following embodiments are exemplified, and are described in detail below with the accompanying drawings. It should be noted that this embodiment is descriptive and not restrictive, and the protection scope of the present invention cannot be limited thereby.

[0011] A baffled anaerobic reactor includes a primary fermentation chamber 1 and a secondary fermentation chamber 6. The top of the primary fermentation chamber and the secondary fermentation chamber are both provided with an outlet weir, and the interior of the primary fermentation chamber and the secondary fermentation chamber are also Three separators 3 are provided, the first-level fermentation chamber is arranged on the left and right sides of the second-level fermentation chamber, and the top of the first-level fermentation chamber is provided with a baffle pipe 7 connecting the first-level fermentation chamber and the...

Abstract

The invention discloses a baffling type anaerobic reactor which comprises primary fermenting chambers and a secondary fermenting chamber. The tops of the primary fermenting chambers and the secondaryfermenting chamber are each provided with an effluent weir, three-term separators are arranged inside the primary fermenting chambers and the secondary fermenting chamber, the primary fermenting chambers are arranged at the left and right sides of the secondary fermenting chamber, and the tops of the primary fermenting chambers are provided with the primary fermenting chamber effluent weirs and baffling tubes arranged at the bottom of the secondary fermenting chamber. The fermenting chambers are matched with the baffling tubes to be communicated with the secondary fermenting chamber, the problems that a traditional UASB tank is poor in dwarf digestion, the tank is high and likely to tilt, and the basic processing cost is high are solved, the existing digestion rate can be effectively increased, blockage caused by excessive suspensions of the three-term separators can be effectively avoided, and therefore the digestibility and the gas producing rate are increased by 10-20%.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a baffled anaerobic reactor. Background technique [0002] In sewage treatment engineering, UASB is the most advanced and most used anaerobic digester in the world. Although the digester has all the advantages, there are also some shortcomings and defects: 1. The tank body must have a large height-to-diameter ratio to have high digestibility and good water quality. 2. Due to the high tank body and the three-phase separator The shielding area is small, and the sewage with more suspended solids is easy to block the three-phase separator. 3. The rising flow rate of suspended solids is too fast to be completely degraded. 4. Due to the high foundation of the tank body, special treatment is required, and the cost of basic treatment is high. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies o...
